Performance Based Seismic Qualification of Large-Class Building Equipment: An Implementation Perspective

Abstract

This paper examines three aspects of nonstructural seismic qualification that become enablers for implementation of performance-based seismic design (PBSD) principles. These include: (1) identification of a nonstructural “large-class” category to address qualification of physically massive and costly equipment platforms, (2) establishment of a systems design framework for earthquake demand allocation at the subsystem level, and (3) introduction of subsystem testing techniques to qualify large-class equipment platforms by testing at the subassembly level. The fundamental premise prescribed in this paper is that implementation of PBSD approaches must be considered during foundation research investigations. Without consideration of the implementation aspect, PBSD will risk rejection by industry. The natural evolution of nonstructural earthquake protection likely points to PBSD, however understanding how to implement PBSD procedures is critical for eventual industry acceptance.
