including Supplement 2 (June 2008).AISI S 214 and S230 references have been updated by a tentative interim amendment (TIA). See page 1.

This comment updates the references to the AISI documents. All supplements are complete andavailable to the public.Supplement No. 2 to the , 2007

edition, includes the following updates and improvements: Included all the changes and updates provided in Supplement No. 1 to the

, 2007 Edition. Supplement 1 to AISI S100,, 2007 Edition, modifies Section F1.1, Load and

Resistance Factor Design and Limit States Design, to recognize that the behavior and probability of failure for acomposite interior partition wall stud differs from the direct load bearing system. Additionally, a reference to SupplementNo. 1 of AISI S213, , is included. TheSupplement also has included errata to the North American Specification. Added new Section B2.5, Uniformly Compressed Elements Restrained by Intermittent Connections. Unified country specific provisions, C2, Tension Members, and the section has moved from Appendices A and B to

the main body of the . Moved the simplified provisions for determine distortional buckling strength of C- or Zsection beams and columns to

the . Revised Sections D1.1, D1.2, D3 and D3.2 to clarify certain terminologies. Consolidated whole Chapter E, Connections and Joints. Additionally, flare groove weld provisions were revised; and

the interaction check of combined shear and tension of arc spot weld was added. Expanded the geometric and material limitations of pre-qualified columns and beams for using the safety and

resistance factors defined in Sections 1.2.1 and 1.2.2, respectivelyChanges made in Supplement 1 to AISI S213,

, 2007 Edition include the following: Rd values in Table A4-1 for diagonal strap braced (concentric) walls were adjusted to match the values approved by

the Canadian National Committee on Earthquake Engineering (CANCEE) for inclusion in the National Building Code ofCanada (NBCC) seismic provisions. Language in C1.1 was modified to clarify when design must comply with the special seismic requirements. The existing provisions on setbacks in Section C2, which the Committee felt should be limited to prescriptive

methods with defined limits of applicability, were replaced with a requirement deemed to be more appropriate for adesign standard. Adjustments were made to Table C2.1-3 for 0.027” steel sheet, one side, based on testing at the University of North

Texas (Yu, 2007). Designation thickness for stud, track and blocking associated with the existing tabulated values wasincreased from 33 mils (min.) to 43 mils (min.). New values were added for designation thickness for stud, track andblocking equal to 33 mils (min.).


Report on Comments – June 2011 NFPA 5000 Equation C2.1-1 for determining the design deflection of a blocked wood structural panel or sheet steel shear wall

was consolidated for SI and Metric units. The word “countersunk” was deleted and commentary added to clarify provisions for tapping screws to attach wood

structural panel sheathing in Section C2.2.2. Language in C3.3.2 was modified to clarify when the uplift anchorage and boundary chords must comply with the

special seismic requirements. Equation D2.1-1 for determining the design deflection of a blocked wood structural panel diaphragm was

consolidated for SI and Metric units.Note: Supporting material is available for review at NFPA Headquarters.

5000-75aConfirm and update all references to ASCE 7-10.

The 2010 edition of ASCE 7 has undergone a major update from the 2005 edition. Not only has thewind load chapter (Chapter 6) been expanded to cover Chapters 26 through 31, but the seismic maps have beenupdated and the associated terminology has been changed. Each reference to ASCE 7 in NFPA 5000 needs to beevaluated for accuracy and updated, if necessary.Note: Supporting material is available for review at NFPA Headquarters.



_______________________________________________________________________________________________Bonnie E. Manley, American Iron and Steel Institute / Rep. Steel Joist Institute

5000-21Revise 2.3.32 as follows:

Steel Joist Institute, 1173B London Links Drive, Forest, VA 245513127 Mr. Joe WhiteAvenue, Myrtle Beach, SC 29577 6760.SJI CJ, 20062010.SJI JG, 20052010

2005.SJI K, 2010.SJI LH/DLH.

20052010.2005.

This comment editorially corrects the SJI references to reflect the actual document titles and updatesthe document editions to 2010. Major changes to the new editions of the SJI standard specifications include thefollowing:· Most significant is the extension of the DLH joist range from maximums of 72” deep

and 144 feet long to maximums of 120” deep and 240 feet long. In conjunction with the increased range, the standardcamber for spans over 100 feet has been reduced and the LH/DLH Load Tables have been converted from a Clearspanto Span basis. An alternate “load/load” method of specifying longspan joists has been introduced. Changes were alsomade with regard to Joist Substitutes and Top Chord Extensions.· Substantial changes were made to the criteria for the spacing of bridging rows and the design of bridging.

The changes make the criteria more cohesive between K-Series and LH-Series joists.· A number of changes were made relative to bearing seat and end anchorage conditions —

primarily incremental criteria rather than one standard for all LH/DLH joists due to the broad range. In addition, designresponsibilities are better defined and additional options for masonry bearing conditions are permitted.· Several design criteria or checks that were already being done but had not been shown in the SPEC

are now included, such as node shear, girder top chord transverse bending, and weld design criteria. Based on SJIresearch, new criteria for crimped end angle webs have been applied.· The Code of Standard Practice is updated with more discussion of the options available

when specifying joists for non-uniform loads.Several other minor changes and editorial/clarification changes are being finalized. Specifically, SJI is in the process of

receiving Public Review and Canvass Committee reviews and ballots for their standards. They anticipate having asecond public review later this fall and plan on completing the standards in the 4th Quarter of 2010.

5000-37Revise definition to read as follows:

3.3.46.3* Thermal Barrier. A material that limits the average temperature rise of an unexposed surface to not morethan 250°F (139°C) for a specified fire exposure complying with the standard time–temperature curve of NFPA 251,Standard Methods of Tests of Fire Resistance of Building Construction and Materials. A material, product, or assemblythat prevents or delays ignition of an unexposed surface by limiting the temperature rise and by acting as a flameexposure barrier for a 15-minute time period.A.3.3.46.3 Thermal Barrier. Finish ratings, as published in the UL Fire Resistance Directory, are one way of determiningthermal barrier. A test method developed in order to assess whether a material, product, or assembly constitutes athermal barrier (NFPA 275) requires thermal barriers to meet both a test for fire resistance (which limits temperature riseon the unexposed side) and for reaction-to-fire (intended to prevent or delay ignition of the material on the unexposedside). The reaction to fire test can be NFPA 286, FM 4880, UL 1040 or UL 1715.

With the development of NFPA 275 the existing definition of thermal barrier is no longer correctbecause thermal barriers both limit the temperature rise and act as a flame exposure barrier, to delay or prevent ignition.The definition and the proposed annex note have been amended to clarify this. This makes the definition more generic.For information: thermal barrier is referred to in NFPA 5000 in the following locations: 26.2.3.6.1 (where it applies more

generically than to foam plastic), 37.4.4 (where it applies to MCMs; NFPA 275 applies also to MCMs), 48.3.3 (where itapplies to foam plastics), 48.4.1.3 (where it applies to foam plastics), 48.4.1.8.3 (which refers back to 48.3.3) and 48.4.3(where it applies to foam plastics).The technical committee should consider whether the revised definition of thermal barrier applies to section 26.2.3.6.1.

The commenter believes it does.In view of the TCC comment and the fact that the committee on Fire Protection Features did not see the action of thecommittee on Structures, Construction, and Materials, this comment is directed at both committees; they acted onproposals 5000-36 and 5000-37 respectively.

5000-68bReject proposal 5000-68b.

This proposal introduces a proprietary concept that is not appropriate for a code or standard because itis not related to the performance of the material. Different methods exist or could be developed to manufacturefire-retardant-treated wood (FRTW) and they may or may not involve the pressure process. The issue is whether FRTWdoes or does not perform as required: flame spread index no larger than 25, no significant progressive combustion andno flame spread beyond 12.5 ft.This proposal also introduces a requirement (that the material must be listed and labeled) which should not be in adefinition but should be in the body of the document. The NFPA Manual of Style does not allow requirements indefinitions. I agree that FRTW should be listed and labeled but the definition should not state this requirement; therequirement should be in a section in the body of NFPA 5000.

Structural tests and inspections for steel materials, fabrication, and erection shall be asrequired by the following:(1) Structural steel construction shall comply with AISC 360 and AISC 341, as applicableTable 40.3.10(a).(2) Cold-formed steel light-frame construction shall comply with Table 40.3.10(a)(b).(3) Other steel construction shall comply with Table 40.3.10(b)

****Insert Table 40.3.10(b) and Table 40.3.10(a) Here****

The recently completed 2010 edition of ANSI/AISC 360,, incorporates a new Chapter N, which addresses comprehensive quality control and quality

assurance requirements for all structural steel construction. These requirements are similar in nature to those that wereincorporated into the 2005 edition of AISC 341, Appendix Q. AISC 360-10, Chapter N provisions provide the foundationfor the quality control and quality assurance requirements for general structural steel construction, with AISC 341-10,Chapter I (previously contained in AISC 341-05, Appendix Q) extending specific requirements to high-seismicapplications.The present Section 40.3.10 addresses all forms of steel construction. The majority of the requirements in Table

40.3.10(a) pertain to structural steel construction. However, there are a few items that are applicable to “steelconstruction other than structural steel”, which are not covered by AISC 360. This comment keeps those particularrequirements while deleting the specific quality assurance requirements for structural steel. For structural steel, a directreference is made in Section 40.3.10 to the more detailed requirements of AISC 360 and AISC 341.Specifically, topics currently in Table 40.3.10(a) that are covered in AISC 360, Chapter N are as follows: Table 40.3.10(a), Fabricator Inspection: AISC 360, Section N (General) Table 40.3.10(a), Materials: AISC 360, Section N5.2 Table 40.3.10(a), Anchor Rods: AISC 360, Section N5.7 Table 40.3.10(a), Bolting: AISC 360, Section N5.6 Table 40.3.10(a), Welding: AISC 360, Section N5.4 Table 40.3.10(a), Shear Connectors: AISC 360, Section N6 Table 40.3.10(a), Structural framing, bracing, details and assemblies: AISC 360, Section N5.7Please note, both AISC 360-10 and AISC 341-10 are complete and summaries of the major changes have been

included with the public comment on Proposal 5000-9.In the 2003 and 2006 editions of NFPA 5000, this table specifically referenced

“light frame cold-formed steel”. However, the charging text in both editions called out “cold-formed steel”. In an attemptto have the text coordinate with the table, “light frame” was deleted from the table in the 2009 edition of NFPA 5000.However, this was not the correct solution; since there are cold-formed steel components addressed in Table 40.3.10(a)– i.e. metal decking. This comment adds “light frame” back into the table and corrects the charging language to reflectthe true scope of the table.

Since the structural steel items have been removed from Table 40.3.10(a), it has beenrecast as applicable to “other steel construction” and moved after the cold-formed steel light-frame construction table.Additionally, the steel joist entry was clarified to apply in field settings only.

Part I of this comment editorially tightens up Section 44.5 by deleting the repetition of the scope ofANSI MH16.1. It also adds language which clarifies that racks can be made from either cold-formed steel or hot-rolledsteel. Finally, to coordinate the 2008 edition of the standard with ASCE 7-10, it is necessary to redirect users to the newASCE 7-10 maps, which are referenced in NFPA 5000, Section 35.10.3.

American Iron and Steel Institute, 1401 Connecticut Avenue, Suite 705, Washington, DC20036.AISI S110, ,

2007, including Supplement 1 (2009).This comment introduces a reference to AISI S110,

which is based upon research conducted by Drs. Uang andSato at UCSD (2007). Specifically, the standard focuses on providing design provisions for a newly defined seismicforce resisting system entitled “Cold-formed Steel – Special Bolted Moment Frame” or CFS-SBMFs. This type of systemis expected to experience substantial inelastic deformation during significant seismic events. It is intended that most ofthe inelastic deformation will take place at the bolted connections, due to slip and bearing. In order to develop thedesignated mechanism, requirements based on the capacity design principles are provided for the design of the beams,columns and associated connections. Additionally, AISI S110 has specific requirements for the application of qualityassurance and quality control procedures.This system has been vetted through the BSSC process and is included in Part I of the 2009 NEHRP Provisions.

Additionally, it has been adopted in the 2010 edition of ASCE 7. ASCE 7-10 has set the Response ModificationCoefficient, R, at 3.5. Cyclic testing has shown that CFS-SBMFs have very large ductility capacity and significanthardening. This justifies the use of a value of 3.5 for the R-factor. The derivation of the deflection amplification factor,Cd, can be found in the AISI S110 Commentary, Section D1.3. Furthermore, a capacity design procedure has beenprovided in Section D1.5 of AISI S110 Commentary so that the designer can explicitly calculate the seismic load effectwith overstrength, Emh,. at the design story drift level. Alternatively, a conservative system overstrength factor, Ωo, is also

provided to be compatible with the conventional approach to compute Emh in ASCE 7. Finally the height limitation of 35feet for all SDCs is based on practical use only and not from any limits on the CFS-SBMF system strength.Modifications to AISI S110 (2007 edition), which were presented in the original proposal in Section 44.6.4, were

developed primarily in the BSSC’s NEHRP process and adopted by ASCE 7 in Chapter 14, which is not adopted inNFPA 5000. However, the modifications to AISI S110-07 no longer need to be adopted in NFPA 5000; last year, theAISI committee responsible for AISI S110 issued a supplement which adopts all of the ASCE 7, Chapter 14modifications.

Note: This comment was developed by the proponent as a member of NFPA’s Building CodeDevelopment Committee (BCDC) with the committee's endorsement.These provisions have been accepted by the NFPA 1 TC as ROP 1-81. We have submitted the text in this comment to

NFPA 5000 because it would be useful to have this information in the building code for new construction. It is intendedthat the provisions be extracted from one document to the other. Proposed section 51.7.2.2.4.3 Item 2 has been shownwith strikeout because the NFPA 1 Technical Committee has deleted it in their committee action. Since the provisionsare related to “green construction”, we believe the Comment is germane to ROP 5000-268.The following is the substantiation from the ROP 1-81:Many buildings are being retrofitted – or built – with photovoltaic (PV) systems. Photovoltaic systems present unique

life & safety hazards to building occupants and firefighters. These electrical systems carry voltages up to 600 v (DC) andcurrents up to 8 amps in residential systems, and there is no way to isolate the power at the modules in the daytimehours. Because of the lifethreatening voltages and current, these systems, not prevalent until recently, pose significantrisks to people on the roofs of these buildings – particularly firefighters, who conduct dangerous ventilation (and other)procedures during fire operations. Photovoltaic system installations should take into consideration the tactics employedby the fire service by providing safe roof access and means for identification of the presence of a PV system. Theseprovisions are intended to address firefighter safety during fire operations.This proposal is modeled after guidelines established by the California State Fire Marshal, entitled Solar Photovoltaic

Installation Guidelines, April 22, 2008, and particularly an ordinance under review by the City of Monterey. TheGuidelines are available on-line at http://www.osfm.fire.ca.gov/pdf/reports/solarphotovoltaicguideline.pdf.The main difference between the guidelines from the California State Fire Marshal and the suggested Monterey

ordinance is that the California guidelines require a three foot setback from the ridge, and a three foot setback from eveto ridge on full hip roof, even when the opposing hip is unobstructed. Whereas, the proposed Monterey ordinancereduces this to 18" (which is supported by many in California) including the requirement for hipped roofs, this reduced


Report on Comments – June 2011 NFPA 5000requirement is in practice in San Francisco.The proposal provides three basic safety measures: it establishes markings on photovoltaic system components to

alert responding firefighters to the dangers of the system, it provides access and pathways within solar module arraysfor roof ventilation and other firefighting duties during fire operations, and it provides other safety measures forfirefighters and others.Drawings similar to those at the end of the California State Fire Marshal Guidelines may be useful to readers of these

code provisions as Annex material. Consideration should be give to including them, with the appropriate 18 inchdimensions noted in this proposal (which differ from those 3 foot dimensions in the Guidelines.)

703-5Accept the proposal as written in the Report on Proposals.

The TCC proposal criticizes the action of the committee as limiting the NFPA document to a uniqueprocess and is based on the negative statement to 5000-69. The substantiation statement clearly outlines the reasonfor the proposal. It was thoroughly discussed during the BLD-BLC committee meeting. This is a definition. Therequirement for pressure treatment is consistent with other standards; notably the 2006 and 2009 edition of theInternational Building Code.

The definition from the 2009 is shown below:Fire-retardant-treated wood. Pressure-treated (emphasis added) lumber and plywood that exhibit reduced

surface-burning characteristics and resist propagation of fire.There are no products currently in the marketplace nor are any products anticipated to be in the marketplace that are

produced by "other means during manufacture". That may be where the confusion arises. Until recently the phrase wasopen to interpretation. It has been clarified in Section 2303.2.2 of the 2009 edition of the

2303.2.2 Other means during manufacture. For wood products produced by other means during manufacture, thetreatment shall be an integral part of the manufacturing process of the wood product. The treatment shall providepermanent protection to all surfaces of the wood product.

The negative voter needs to identify what other "manufacturing processes" he has identified. One thought is it may bea coating or paint. NFPA 5000 is clear in Section 10.3.1.3 that for new construction they can not be used to reduceflame spread.




703-5Reject proposal 703-5.

This proposal introduces a proprietary concept that is not appropriate for a code or standard because itis not related to the performance of the material. Different methods exist or could be developed to manufacturefire-retardant-treated wood (FRTW) and they may or may not involve the pressure process. The issue is whether FRTWdoes or does not perform as required: flame spread index no larger than 25, no significant progressive combustion andno flame spread beyond 12.5 ft.

This proposal also introduces a requirement (that the material must be listed and labeled) which should not be in adefinition but should be in the body of the document. The NFPA Manual of Style does not allow requirements indefinitions. I agree that FRTW should be listed and labeled but the definition should not state this requirement; therequirement should be in a section in the body of NFPA 703.

In fact, section 4.5 already includes the requirement that these materials must be listed and labeled.The rejection of proposal 703-5 should not affect the continued acceptance of proposal 703-4, which contains needed

editorial changes.

703-11Add text to read as follows:

A.3.3.2 Wood or wood products with topically applied materials or chemicals are not “fire-retardant treated wood”.Fire-retardant treated wood is required to be “pressure treated”. The treatment becomes an integral part of the wood.Pressure treatment is done in closed vessels under pressures not less than 50 pounds per square inch gauge (psig)(345 kPa). (International Building Code, Section 2303.2.1). Because topically applied material is usually done to onlyone side it is only tested on one side. The treatment for fire-retardant treated wood is required to be symmetrical.Pressure treatment insures that it is.

The proposed revision will further clarify the manufacture and testing differences in the two products.

703-11Add text to read as follows:

A.3.3.2 Wood or wood products with topically applied materials or chemicals are not “fire-retardant treated wood”.Fire-retardant treated wood is required to be “pressure treated” or “other means during manufacture”. In both instancesthe treatment becomes an integral part of the wood. Pressure treatment is done in closed vessels under pressures notless than 50 pounds per square inch gauge (psig) (345 kPa). (International Building Code, Section 2303.2.1). For woodproducts produced by “other means during manufacture”, the treatment is a fundamental part of the manufacturingprocess of the wood product. The treatment must provide permanent protection to all surfaces of the wood product.(International Building Code, Section 2303.2.2.) Because topically applied material is usually done to only one side it isonly tested on one side. The treatment for fire-retardant treated wood is required to be symmetrical. Pressuretreatment insures that it is. For wood products produced by other means during manufacture all sides of the woodproduct shall be tested in accordance with and produce the results required in Section 3.3.2. Only the front and backfaces of wood structural panels need to be tested. (International Building Code, Section 2303.2.3.)

The proposed revision will further clarify the manufacture and testing differences in the two products.
