Özet
This study investigates the performance of the Instantaneous Power (IP(T-1)) intensity measure (IM) for predicting the structural collapse of structures under near-fault pulse-like ground motions. The efficiency and sufficiency of vector IM consisting of elastic spectral acceleration at the fundamental period of the structure (Sa(T-1)) and IP(T-1) are compared with those obtained using Sa(T-1), average spectral acceleration (Sa(avg)), and spectral shape-based vector IMs. A proportional reduction in error, which quantifies to what extent the other ground-motion parameter eliminates the error in the collapse capacity prediction relative to IM of interest, is used to assess the sufficiency. Our findings reveal that [Sa(T-1), IP(T-1)] yields better collapse capacity prediction compared to all IMs considered and is found to be sufficient with respect to most of the seismological parameters, duration-related IMs, pulse period, and scale factor.
