A Framework for the Quantification of Non-Structural Seismic Performance Factors

With the advancement of performance-based earthquake engineering (PBEE), the seismic performance of non-structural elements (NSEs) has gained special relevance. The harmonization of the performance of NSEs and of the seismic force-resisting system (SFRS) in a building is fundamental to the PBEE concept. To provide a consistent level of performance for force-based designed SFRSs, the FEMA P695 Methodology provides an objective framework. No equivalent procedure currently exists for NSEs. This paper develops a framework to quantify seismic performance factors for NSEs. An illustrative case study example is presented for the calibration of the behaviour factor for suspended piping seismic restraint installations.
