Abstract

This research investigates the efficiency of the Self-centering steel braced frame equipped with replaceable yielding fuses and post-tensioning cables subjected to Far-field records and Near-field pulse-like ground motions. For this purpose, engineering seismic demand parameters for tewelve Self-centering steel braced frames under Far-field ground motions are compared with those for Near-field ground motions. The braced frames are different from seismic frame type, seismic site location, and the number of stories. The Self-centering braced frames are designed using a limit-state design procedure and are simulated in OpenSees software. NonliNear dynamic time-history analyses are conducted under design earthquake, DBE, level and maximum considerable earthquake, MCE, level. Findings demonstrate that the Self-centering steel braced frames are capable of mitigating seismic damage under both Near-field pulse-like and Far-field ground motions, which are provided by features such as rocking behavior, re-centering action, and directing damage ability.
