Generic Methodology to Establish Model Building Code Compliance Acceptance Criteria for Qualification of OFC's by Shake Table Test

Abstract eng:
Structural engineers address the seismic resilience of facilities essential for post earthquake recovery on a site specific design basis. Manufacturers of Operational and Functional Components (OFC’s, also referred to as nonstructural building components) cannot economically afford to consider seismic resilience of their equipment on a site specific basis at a price the market is willing to bear. Therefore manufacturers pursue a cost effective qualification process which envelopes a wide variety of product configurations to meet or exceed the seismic requirements for the maximum geographic area possible. Typically the design professional relies on an accepted model building code to insure a minimum level of earthquake performance. For the latest generation of model codes (similar to the USA FEMA NEHRP Provisions, National Earthquake Hazards Reduction Program) the trend is to improve and more directly address the prescriptive requirements for OFC’s. While it is now possible for a modern model building code to better state seismic requirements for OFC’s, they cannot communicate the intent behind these requirements because of their prescriptive nature. Therefore an acceptance criteria created by those who established the referenced model code foundation is essential to guide manufactures on how establish a qualification by test program for OFC’s to insure consistency in compliance. This paper details a generic methodology to create an acceptance criteria for OFC’s based on lessons learned from the creation of the first such acceptance criteria for the NEHRP influenced USA model building codes, ICC ES AC156.
