7 Drivers of Change Earthquake Lessons Learned 7

8 Special Seismic Certification is Also Known As (AKA) Seismic Certification of Nonstructural Components (IBC 2009 Section and the CBC 2010 Section 1708A.4) Special Certification for Designated Seismic System (ASCE 7-05 Section ) 8

9 Codes and Standards Relationship 9

10 What is Designated Seismic System? Any Component or System with Importance Factor (I p )i is Greater than 1.0 is called Designated Seismic System (CBC 2010 Section 1702A) 10

11 Nonstructural Component Importance Factor Component Importance (I p ) is either 1.0 or 1.5 (ASCE 7-05 Section ) Component Importance (I p ) is 1.5 if: Component is required to function for life-safety Component contain hazardous materials Components is in essential facilities and its failure could impair the continued operation of the facility 11

12 Intent of Building Code Provide reasonable assurance of seismic performance that will: 1. 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. 12

13 Statutory Mandate for OSHPD HOSPITAL FACILITIES SEISMIC SAFETY ACT 1983 (HSSA 83) Hospital buildings that house patients who have less than the capacity of normally healthy persons to protect themselves must be reasonably capable of providing services to the public after a disaster 13

14 Seismic Performance of Nonstructural Components Damage to nonstructural components can result in: Significant economic losses Cost of building contents exceeds building cost Temporary partial/total loss of operation/functionality Injuries and Loss of Life Past Emphasis: Life Safety and Position Retention only Present Focus: Maintaining Functionality 14

15 Special Certification for Designated Seismic Systems Section of ASCE 7-05 Special Certification is required for Designated Seismic Systems assigned to Seismic i Design Categories C through F as follows: Active mechanical and electrical equipment that are required to function following the Design Earthquake Components containing hazardous contents 15

16 Seismic Certification of Nonstructural Components CBC 2010 Section 1708A.4: The registered design professional shall state the applicable seismic certification requirements for nonstructural components and designated seismic systems on the construction documents. CONT D 16

17 CBC 2010 Section 1708A.4 Seismic Certification of Nonstructural t Components The manufacturer of each designated seismic system components subject to the provisions of ASCE 7 Section shall test or analyze the component and its mounting system or anchorage and submit a certificate of compliance for review and acceptance by the registered design professional responsible for the design of the designated seismic system and for approval by the building official. CONT D 17

18 CBC 2010 Section 1708A.4 Certification shall be based on: An actual test on a shake table, Seismic Certification of Nonstructural Components By three-dimensional shock tests, By an analytical method using dynamic characteristics and forces, By the use of experience data (i.e., historical data demonstrating acceptable seismic performance), or By more rigorous analysis providing for equivalent safety. 18

19 Seismic Certification by Analysis 19

20 Seismic Certification by Analysis Seismic Certification of Tanks by Analysis Using ASME BPVC Tanks (without vibration isolators) designed by: 1. A registered design professional in accordance with ASME Boiler and Pressure Vessel Code, 2007 (BPVC 2007); and, 2. Satisfying the force and displacement requirements of Sections and of ASCE 7-05 having an importance factor, I = 1.5; and, 3. Reviewed and approved by OSHPD Shall be considered to satisfy the Special Seismic Certification requirements on the basis of ASCE 7-05 Section

21 Seismic Certification by Analysis Seismic Certification of Tanks by Analysis Using ASCE 7-05 Chapter 15 Tanks Classified as Nonbuilding Structures in ASCE 7-05 shall be considered to satisfy Special Seismic Certification requirements if all of the following conditions are satisfied: 1. Tank design is in accordance ASCE 7-05 Chapter 15 with R = 0 = C d = 1, and 2. Attachments and Supports are designed in accordance with ASCE 7-05 Chapter 15 with R, 0, and C d values provided therein, and 3. Tank design is reviewed and approved by OSHPD. 21

22 Seismic Certification by Analysis For 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 is not a destructive test, hence tested unit may be installed and used 22

23 ASCE/SEI 7-05 Referenced Seismic Qualification Testing Protocol 23

24 AC-156 Seismic Qualification by Shake Table Testing of Nonstructural Components Companion Document to 2009 IBC/ASCE 7-05 Acceptance Criteria published by ICC Evaluation Services First published in 2000, latest version 2007 Provides testing protocol and test spectra definition iti Test Spectra is tied directly to F p force equation Acceptance Criteria tied to I p factor. For I p = 1.5, Equipment to remain functional following the test 24

29 Seismic Certification by Experience Requirements for Qualification by Experience Data (for OSHPD) Characterization of experience motions as measured by instruments t Verification of post-earthquake Functionality and Structural Integrity Equipment must be of equal or better construction Project seismic demand must be less than Certification basis Requires maintenance of data base for continuous evaluation of the performance of installed equipment experiencing new earthquake 29

30 HOSPITAL FACILITIES SEISMIC SAFETY ACT 1983 (HSSA 83) Hospitals housing patients less able to protect themselves; Legislative intent 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. In order to accomplish this purpose, the office shall propose proper building standards for earthquake resistance based upon current knowledge 30

34 CBC 2010, Section 1708A.4 Components Exempt from Special Seismic Certification: 1. Equipment and components installed in nonconforming buildings unless the equipment or component provides a service/system or utility to conforming buildings, or building is designated as SPC 3 or higher. 1. Equipment and components weighing not more than 20lbs. supported directly on structures (and not mounted on other equipment or components) with supports and attachments in accordance with a SCE 7 Chapter 13 as modified by Section 1615A. 34

35 CBC 2010, Section 1708A.4 Special Seismic Certification for OSHPD 2 and 3 Buildings: Special Seismic Certification is required for Designated Seismic System (components with importance factor equal to 1.5). Typical components that require special seismic certification in OSHPD 2 & 3 buildings include: Emergency generators Automatic transfer switches Smoke control fans Medical gas systems Fire alarm panels 35

36 CBC 2010 Section 1708A.4/ASCE 7-05 Section : 2 Special Seismic i Certification Special Seismic Certification for Designated Seismic System, ASCE/SEI 7-05 Section and CBC 2010 Section 1708A.4 Analysis Testing Experience Data ASCE/SEI7-05 Sections 13.3, 13.4, 13.5, & 13.6 ASCE/SEI 7-05 Section ASCE/SEI 7-05 Section Project Specific Submittal to OSHPD OSHPD Special Seismic Certification Preapproval (OSP) 36

37 OSHPD Special Seismic Certification Preapproval (OSP) OSP requirements of a product line with similar structural configuration: Testing of at least two units (typically the smallest & largest units), and Verification of similarities il iti for interpolated t units (CBC 2010 Section 1708A.4). 37

38 Special Seismic Certification By a Single Test One dynamic test is Acceptable when: A single product is certified NOT a product line with more than one product with variations; and, Manufacturing process is ISO 9001 certified 38

39 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. 39

40 Statutory OSHPD Review Requirements 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 and constructed t 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 provide an independent d review of the design and construction of hospital buildings. 40

41 Regulatory OSHPD Approval Requirements CBC A.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 design professional, are also subject to approval by the enforcement agency. 41

42 Is Third Party Review Subject to OSHPD Review and Approval? Yes Required by Statutet t Required by the CBC 2010 Section 1601A.3 42

43 No Can the Analysis be Bookended Similar to Testing? Analysis is only good for the unit analyzed limited variations and/or grouping may be acceptable i.e. analysis of the smallest and largest buildings (under OSHPD jurisdiction) can t be used for permitting all OSHPD buildings (of a given structural t configuration). However, testing of a few connections to verify an analysis methodology can justify all connections of similar configurations 43

44 What R p Can be Used for Special Seismic Certification? R p = 1.0 & I p = 1.5 for Special Seismic Certification by Analysis (Attachments design can use R p in ASCE 7), Since Functionality can t be Verified by Analysis R p/i p = 1.0 for Special Seismic Certification by Shake Table Test. Both Structural Integrity and Functionality shall be maintained after shake table test. 44

45 Why is R p based on the AC-156 Requirements? ASCE 7-05 does not provide R p 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 electrical equipment. ICC-ES AC 156 requires R p/i p = 1 for Shake Table Test. 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

46 Can the Active Mechanical & Electrical Equipment get an OSP by analysis alone? No Active and energized components must be certified by shake table testing or experience data. ONLY connecting elements, attachments, and supports can be justified by supporting analysis for active and energized components 46

47 Does the Design need to comply with the CBC 2010 for OSP? Yes All components shall be designed in accordance with 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 as required by the code. The CBC does not permit 1/3 rd allowable stress increase for most materials, including steel and concrete. 47

48 OSHPD Special Seismic Certification Preapproval (OSP) at OSHPD Website OSHPD Special Seismic Certification Preapproval (OSP) Requirements and Application form is available at: List of Equipment and Components with OSHPD Special Seismic Certification Preapproval (OSP) is available at: Approval/special_seismic_cert_pre-approval.html 48

49 Progress in OSHPD Special Seismic Certification Preapproval (OSP) More 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

50 Options When No Equipment with Special Seismic Certification is Available Differ the Special Seismic Certification and Require the Manufacturer to Provide the Certification Certification must be complete prior to installation. Emergency Waiver OSHPD may waive the requirements for emergency replacements 50

51 Yes Does HVAC Unit for CT Scanner Room Require Special Seismic Certification for the CBC 2007? The CBC 2007 Section 1708A.5 require special seismic certification of all equipment with importance factor (I p ) 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 earthquake. Loss of equipment such as acid filled UPS batteries may create a hazardous materials situation, which may affect other functions in the hospital. 51
