Special Seismic Certification is ( )Also Known As (AKA)

• Seismic Certification of Nonstructural Components (IBC 2009 Section 1708.4 and the CBC 2010(Section 1708A.4)

• Special Certification for Designated Seismic System(ASCE 7-05 Section 13.2.2)

Codes and Standards RelationshipCodes and Standards Relationship

What is Designated Seismic System?What is Designated Seismic System?

• Any Component or System with Importance F t (I ) i G t th 1 0 i ll dFactor (Ip) is Greater than 1.0 is called Designated Seismic System (CBC 2010 Section 1702A))

10

Nonstructural Component Importance Factor

• Component Importance (Ip) is either 1.0 or 1.5 (ASCE 7-05 Section 13.1.3)

• Component Importance (Ip) is 1.5 if:– Component is required to function for life-safety– Component contain hazardous materials

C t i i ti l f iliti d it f il– Components is in essential facilities and its failure could impair the continued operation of the facility

11

Intent of Building CodeIntent of Building Code

• Provide reasonable assurance of seismic performance that will:

1 Avoid serious injury and life loss1. Avoid serious injury and life loss,2. Avoid loss of function in critical

facilities,3. Minimize structural and nonstructural

repair costs where practical to do so.

Seismic Performance of Nonstructural Components

• Damage to nonstructural components can result g pin:– Significant economic losses

• For a product line with multiple products analysis is tooFor a product line with multiple products analysis is too time consuming. Active and Energized components must be qualified by test or experience data.

• Analyzing a custom 40-units HVAC product line will be similar to designing 40-hospital buildings.

• Same HVAC product line can be qualified by just two shake table test.shake table test.

• Shake Table test is not a destructive test, hence tested nit ma be installed and sedunit may be installed and used

OSHPD Special Seismic Certification Preapproval (OSP)

• OSP requirements of a product line withOSP requirements of a product line with similar structural configuration:

– Testing of at least two units (typically the smallest & largest units) andsmallest & largest units), and

V ifi ti f i il iti f i t l t d it– Verification of similarities for interpolated units (CBC 2010 Section 1708A.4).

37

Special Seismic Certification By a Single Test

– A single product is certified• NOT a product line with more than one product with

variations; andvariations; and,

– Manufacturing process is ISO 9001 certified

38

OSP Requirements (Continued)OSP Requirements (Continued)

• OSHPD strongly recommends:– The Owner and his California licensed

structural engineer meet and review the proposed test plan with OSHPD prior to any testing to ensure that there will be no issues with the OSP approval when submitted.

Statutory OSHPD Review Requirements

§129680. Hospitals housing patients less able to protect themselves; Legislative Intent

(a) It is the intent of the Legislature that hospital buildings that house patients who have less than the capacity of normally healthy persons to protect themselves, and that must be reasonably capable of providing services to the public after a disaster, shall be designed

d t t d t i t i f ti l th f t d b th kand constructed to resist, insofar as practical, the forces generated by earthquakes,

gravity, and winds. In order to accomplish this purpose, the office shall propose

proper building standards for earthquake resistance based upon current knowledge, and

id i d d t i f th d iprovide an independent review of the design and construction of hospital buildings.

Regulatory OSHPD Approval Requirements

1601A 3 Enforcement Agency Approval In addition to requirements of California Code

CBC 2010

1601A.3 Enforcement Agency Approval. In addition to requirements of California Code

of Regulations (C.C.R.) Title 24, Parts 1 & 2, any aspect of project design, construction, quality assurance, or quality control programs for which this code requires approval by the designthis code requires approval by the design professional, are also subject to approval by the enforcement agency.

41

Is Third Party Review Subject to OSHPD Review and Approval?

• YesYes

R i d b St t t• Required by Statute

• Required by the CBC 2010 Section 1601A.3

42

Can the Analysis be Bookended Similar to Testing?

• NoNo• Analysis is only good for the unit analyzed

– limited variations and/or grouping may be acceptablelimited variations and/or grouping may be acceptable– i.e. analysis of the smallest and largest buildings

(under OSHPD jurisdiction) can’t be used for itti ll OSHPD b ildi ( f i t t lpermitting all OSHPD buildings (of a given structural

configuration).– However testing of a few connections to verify anHowever, testing of a few connections to verify an

analysis methodology can justify all connections of similar configurations

43

What Rp Can be Used for Special Seismic Certification?

• Rp = 1.0 & Ip= 1.5 for Special Seismic Certification by Analysis (Attachments design can use Rp in ASCE 7), Si F ti lit ’t b V ifi d b A l iSince Functionality can’t be Verified by Analysis

• Rp/Ip = 1.0 for Special Seismic Certification by Shake p p p yTable Test. Both Structural Integrity and Functionality shall be maintained after shake table testtable test.

44

Why is Rp based on the AC-156 Requirements?

• ASCE 7-05 does not provide R values for specialASCE 7 05 does not provide Rp values for special seismic certification of active electrical and mechanical equipment, since it does not provide analysis as an option for special certification of active mechanical and p pelectrical equipment.

• ICC-ES AC 156 requires Rp/Ip = 1 for Shake Table Test.q p p– Require Post-Test Structural Integrity for Ip = 1– Require Post-Test Structural Integrity and Functionality for Ip

= 1.5

• Critical equipment and components should remain essentially elastic for post-earthquake functionality

45

Can the Active Mechanical & Electrical E i t t OSP b l i l ?Equipment get an OSP by analysis alone?

• NoNo

• Active and energized components must be certified by shake table testing or experience data.

• ONLY connecting elements, attachments, d t b j tifi d b tiand supports can be justified by supporting

analysis for active and energized components

46

Does the Design need to comply with the CBC 2010 for OSP?

• YesYes

• All components shall be designed in accordance with the CBC requirementswith the CBC requirements– Both demand and capacity shall be based on the CBC

and referenced material standards.• Stability and local affects shall be part of the design y p g

as required by the code.• The CBC does not permit 1/3rd allowable stress

increase for most materials, including steel and gconcrete.

Progress in OSHPD Special Seismic Certification Preapproval (OSP)

• More than seventy Special Seismic CertificationMore than seventy Special Seismic Certification Pre-Approvals to date (OSP Program started in July, 09).

10,000 Equipment

• Currently processing on average more than three (3) new OSP’s per week

• Most Categories have Multiple Pre-approvals

49

Options When No Equipment with Special Seismic Certification is Available

• Differ the Special Seismic Certification and Require the Manufacturer to Provide the CertificationCertification – Certification must be complete prior to installation.

• Emergency Waiver – OSHPD may waive the requirements for emergency replacements

50

Does HVAC Unit for CT Scanner Room Require

• Yes

Special Seismic Certification for the CBC 2007?

Yes• The CBC 2007 Section 1708A.5 require special seismic certification of

all equipment with importance factor (Ip) of 1.5.

• The CBC 2010 will require CT Scanners to have special seismic certification (Every Manufacturer of CT scanners are expected to have qualified scanners by July, 2010)

• If CT Scanners are out of service, that room can be converted to another service following earthquake provided all support equipment are functional All rooms may become essential after an earthquakeare functional. All rooms may become essential after an earthquake.

• Loss of equipment such as acid filled UPS batteries may create a hazardous materials situation, which may affect other functions in the hospitalhospital.
