• Introduction• Current Conditions• Background / History• Standards• Enforcement• Best Practice• Certification• Q&A Discussion

Sep 15, 2014

Current Conditions

• In a Round Table Discussion with OSHPD Director onApril 22, 2014 we learned:– The Majority of Work in Progress at OSHPD are Projects

with Construction Value < $ 200,000– Only a Couple of Large Projects under Construction

• Sutter: CPMC San Francisco• Kaiser: San Diego• Stanford: Palo Alto

– Marked Decline in Work Volumes Attributed to:• General Economic Conditions• Healthcare Reform• Seismic Compliance Delays

Background / History

Sep 15, 2014

What about the “Black Box”?


Sep 15, 2014

1976 UBC

(k) Essential Facilities. Essential facilities are those structures orbuildings which must be safe and usable for emergency purposes afteran earthquake in order to preserve the health and safety of the generalpublic. Such facilities shall include …

…The design and detailing of equipment which must remainin place and be functional following a majorearthquake shall be based upon the requirements of Section 2312(g) [Lateral Force on Elements of Structures] and Table No. 23-J.

Good idea but doesanyone really care?


Sep 15, 2014

2000 IBC1708.5 Mechanical and electrical equipment. Eachmanufacturer of designated seismic system components shalltest or analyze the component and its mounting system oranchorage and shall submit a certificate of compliance… Theevidence of compliance shall be by actual test on a shaketable, by three-dimensional shock tests, by an analyticalmethod using dynamic characteristics and forces, by theuse of experience data (i.e., historical data demonstratingacceptable seismic performance), or by a more rigorousanalysis providing for equivalent safety.

Maybe we do care?

Drivers of Change - Earthquake Lessons Learned


Sep 15, 2014

2006 IBC / 2007 CBC1708.5 Seismic qualification of mechanical and electrical equipment.The registered design professional in responsible charge shall state theapplicable seismic qualification requirements for designated seismicsystems on the construction documents…

…Qualification shall be by an actual test on a shake table, by three-dimensional shock tests, by an analytical method using dynamiccharacteristics and forces, by the use of experience data (i.e.,historical data demonstrating acceptable seismic performance) or bya more rigorous analysis providing for equivalent safety.

Yes, we care. So nowwhat?

Codes and Standards

Sep 15, 2014

What Changed?

• IBC vs CBC: Some Noteworthy Difference inRequirements for SSC.

• Enforcement has been the Source of PERCEIVEDCHANGE.

• On January 1, 2008 OSHPD began to enforce therequirement for SSC as prescribed in the 2007 CBC.

• Even today, many jurisdictions still do not enforce thispart of the building code.

Enforcement

Sep 15, 2014

• Validate the Structural Integrity andFunctionality of the Equipment.

• Validate the Seismic Anchorage andRestraint of the Equipment

Best Practice

Sep 15, 2014

Gather the Critical Information

• Essential Site / Building Information

• Essential “Building Systems / EquipmentComponents” Information

Best Practice

Sep 15, 2014

Essential “Site / Building” Information

• Site Class• Spectral Accelerations• Risk (Occupancy) Category• Seismic Design Category• Permanent or Temporary Installation• General Structural System• Support Compatibility• Installation Location in the Building

Best Practice

Sep 15, 2014

Risk (Occupancy) Category

• Essential Buildings: IV– I-2 Occupancies (Hospitals)– Fire, Rescue ambulance, Police Stations– Designated Earthquake Shelters, Emergency Preparedness,

communications and operations centers.– Structures Containing Toxic Materials– Aviation Control Towers, Buildings having National Defense

Functions– Water Storage and Pump Structures for Fire Suppression

Best Practice

Sep 15, 2014

Essential “Building Systems / Equipment Components”

• Component Importance Factor• Designated Seismic Systems• Amplification Factor ap• Response Modification Factor Rp• Exemptions to design requirements of ASCE 7-10,

Chapter 13• Manufacturer Special Seismic Certification• Manufacturer OSHPD Pre-Approvals (Voluntary

Programs)• Manufacturer Product Data Information (Cut Sheets)

Best Practice

Sep 15, 2014

• Manufacturer’s Certification by Analysis, ShakeTable Testing or Experience Data. (NOTSpecial Seismic Certification)

• Manufacturer Installation Drawings• Support Conditions (Flexible / Rigid, Floor,

Overhead, Wall Mounted)• Specialty Support Documentation (Vibration

Isolation)

Essential “Building Systems / Equipment Components”Best Practice

Sep 15, 2014

Designated Seismic Systems• The seismic force-resisting system and those

architectural, electrical, and mechanical systemsor their components that require design inaccordance with ASCE 7-10, Chapter 13 and forwhich the component Importance Factor isgreater than 1.0.

• Equipment that is part of the Designated SeismicSystem must remain Operable following anEarthquake

Best Practice

Sep 15, 2014

Component Importance Factor (Ip)

• All components shall be assigned an Ip value.

• Ip = 1.0 except where…– The component is required to function for life-safety

purposes. (Fire Alarm and Fire Sprinkler Systems). Ip=1.5– The component contains hazardous materials. (Fuel

Tanks etc). Ip=1.5– The component is in or attached to an Risk Category IV

Structure. Ip=1.5

Best Practice

Sep 15, 2014

Certification Methods

• Project Specific Special Seismic Certification andSeismic Restraint Calculations.• Applicable to the Site and Project Conditions

Only.

• Pre-Approved Special Seismic Certification(OSHPD OSP Program) and Anchorage (OPMProgram• Applicable to Multiple Sites where Site

Conditions and Product Construction areAcceptable

Sep 15, 2014

Site / Project Specific Certification

• The Design Professionals of Record for theproject are responsible to VALIDATE theapplication of a Special Seismic Certificationfor their specific project. Must includespecific information from shake table testing.

• The Design Professionals of Record areresponsible to VALIDATE EquipmentAnchorage
