Page 2 of 11 ESR-1056

3.2.1 General: Anchors described in this report areassigned allowable tension and shear loads for designsbased on allowable stress design (working stress design).Use of the anchors to resist vibratory and moving loads, suchas those produced by reciprocating engines, cranes andvehicles, is beyond the scope of this report.

3.2.2 Design of Anchors in Normal-weight Concrete:Allowable tension and shear loads for installation in normal-weight concrete are noted in Tables 3 through 6. Spacing andedge distance requirements are noted in Tables 1 through 6.Allowable load reduction factors noted in Table 2 areapplicable only to the allowable loads shown in Tables 3 and4.

For installations in normal-weight concrete, anchors arerecognized to resist dead-, live-, wind-, and earthquake-loadapplications. Allowable loads may be increased by 331/3

percent when using the alternate basic load combinations inaccordance with Section 1605.3.2 of the IBC or Section1612.3.2 of the UBC, for wind or earthquake loadingconditions. Alternatively, the load combinations in IBC Section1605.3.2 may be multiplied by a factor of 0.75.

Allowable loads for anchors installed in normal-weightconcrete subjected to combined shear and tension forcesshall be determined by the following equation:

where:

3.2.3 Design of Anchors Installed in the Top or Bottomof Structural Sand-lightweight Concrete Filled Metal-deckAssemblies: Allowable tension and shear loads, and spacingand edge distance requirements, for anchors installed in thetop or bottom of structural sand-lightweight concrete filledmetal-deck assemblies are noted in Table 7. Refer to Figure2 for required assembly details.

Anchors installed in the top of structural sand-lightweightconcrete and metal-deck assemblies may resist wind orearthquake loads. Allowable tension and shear loads may beincreased by 331/3 percent when using the alternate basicload combinations in accordance with Section 1605.3.2 of theIBC or Section 1612.3.2 of the UBC, for wind or earthquakeloading conditions. Alternatively, the load combinations in IBCSection 1605.3.2 may be multiplied by a factor of 0.75.

Anchors installed in the bottom of structural sand-lightweight concrete and metal-deck assemblies may resistwind or earthquake loads:

Allowable tension loads for bottom deck installations maybe increased by 331/3 percent when using the alternate basicload combinations in accordance with Section 1605.3.2 of theIBC or Section 1612.3.2 of the UBC, for wind or earthquakeloading conditions. Alternatively, the load combinations in IBCSection 1605.3.2 may be multiplied by a factor of 0.75.

Allowable shear loads for bottom deck installations shall notbe increased when using the alternate basic loadcombinations in accordance with Section 1605.3.2 of the IBCor Section 1612.3.2 of the UBC, for wind or earthquakeloading conditions.

Allowable loads for anchors installed into the top or bottomof structural sand-lightweight concrete filled metal-deck

3.2.4 Design of Anchors Installed in Fully Grouted CMUMasonry Walls: Allowable tension and shear loads foranchors installed in the face of fully grouted CMU masonrywalls are noted in Table 8A for structures complying with theIBC or IRC, and Table 8B for structures complying with theUBC. The allowable tension and shear loads are for anchorsinstalled in the grouted cells, the center web of CMU units,and horizontal mortared bed joints of fully grouted CMUmasonry wall construction. Allowable loads for anchorsinstalled in the vertical head joint or the end flanges of theCMU units are outside the scope of this report. Edge and enddistances, and spacing requirements for anchors installed inthe face of fully grouted CMU masonry walls, as shown inFigure 3, are noted in Tables 8A and 8B. Allowable loadreduction factors for anchors installed at reduced edge andend distances, and reduced spacing, are noted in Tables 9and 10.

Allowable tension and shear loads for 1/2-inch and 5/8-inch(12.7 mm and 15.9 mm) anchors installed in the top of fullygrouted concrete masonry walls (CMU grouted cores andCMU webs), are noted in Table 11A for anchors installed instructures complying with the IBC or IRC, and Table 11B foranchors installed in structures complying with the UBC.

When using the alternate basic load combinations in IBCSection 1605.3.2 or UBC Section 1612.3.2 that include windor earthquake loads, the allowable shear and tension loadsfor anchors installed in the face and the top in fully groutedCMU masonry walls may be increased by 331/3 percent.Alternatively, the load combinations in IBC Section 1605.3.2may be multiplied by a factor of 0.75.

Allowable loads for anchors installed in the face of fullygrouted CMU masonry walls subjected to combined shearand tension forces shall be determined by the followingequation:

4.0 INSTALLATION

4.1 General:

Titen HD screw anchors shall be installed by drilling a pilothole into the substrate using a handheld electro-pneumaticrotary hammer drill with a carbide-tipped drill bit conformingto ANSI B212.15-1994. The pilot hole shall have the samediameter as the nominal diameter of the anchor. The hole isdrilled to the specified embedment depth plus 1/2 inch (12.7mm). Dust and debris in the hole shall be removed by using

Page 3 of 11 ESR-1056

oil-free compressed air. The Titen HD screw anchor shall beinstalled into the hole to the required embedment using asocket wrench or powered impact wrench.

4.1.1 Anchors Installed in Fully Grouted CMU MasonryWalls: Anchors installed in the face of fully grouted CMU wallconstruction shall be limited to the face shell of the CMU unit(center web and grouted cores) and the horizontal mortaredbed joints, as indicated by the shaded areas in Figure 3.Anchors installed in a T-joint, the mortared head joint, or theend webs of a CMU unit, as indicated in the non-shadedareas in Figure 3, are outside the scope of this report.

For anchors installed in the top of fully grouted concretemasonry walls (CMU grouted cores and CMU webs), anchorlocation shall comply with the minimum edge and enddistances noted in Tables 11A and 11B and shown in Figure4. Anchors installed in the mortared head joint are outside thescope of this report

4.2 Installation with Special Inspection (WhenRequired):

Continuous special inspection shall be provided whenrequired by the tables in this evaluation report. Specialinspection under the IBC and IRC shall conform to IBCSection 1704; under the UBC, special inspection shall be inaccordance with UBC Section 1701.

For fasteners installed with special inspection, the followingitems, as applicable, shall be inspected: fastener type anddimensions; concrete type and concrete compressivestrength (for anchors installed in concrete); masonry unit typeand compliance with ASTM C 90; grout and mortarcompressive strengths, and (when required) masonry prismcompressive strength; drill bit size and compliance with ANSIB212.15-1994; and fastener embedment, spacing, and edge(and end) distances. The special inspector shall inspect andverify that anchor installation complies with this evaluationreport and Simpson Strong-Tie Company’s publishedinstallation instructions.

5.0 CONDITIONS OF USE

The Titen HD Screw Anchors described in this report complywith, or are suitable alternatives to what is specified in, thecodes listed in Section 1.0 of this report, subject to thefollowing conditions:

5.1 Anchors are identified and installed in accordance withthis report and the manufacturer’s published installationinstructions.

5.2 Anchors installed in normal-weight concrete to resistdead, live, wind and earthquake load applications shallbe in accordance with Section 3.2.2.

5.3 Anchors installed into the top or bottom of structuralsand-lightweight concrete filled metal-deck assembliesto resist dead, live, wind and earthquake loadapplications shall be in accordance with Section 3.2.3.

5.4 Anchors installed in the face or the top of fully groutedCMU masonry walls to resist dead, live, wind, andearthquake load applications shall be in accordancewith Section 3.2.4.

5.5 Since an ICC-ES acceptance criteria for evaluating datato determine the performance of anchors subjected tofatigue or shock loading is unavailable at this time, theuse of these anchors under these conditions is beyondthe scope of this report.

5.6 Anchors are not permitted for use in conjunction withfire-resistive construction. Exceptions would be:

• Anchors resist wind or seismic loading only.
