Seismic fragility assessment for moment-resisting concrete frame with setback under repeated earthquakes
https://orcid.org/0000-0002-0712-0705
Abstract This research study was carried out to analyse the seismic behaviour of ten types of six-storey moment-resisting concrete frames, which were one regular frame and nine setback frames with different building configurations. In this analysis, the setback buildings were mainly studied because they have become increasingly popular in modern multi-storey building construction due to their functional and aesthetic architecture. Incremental dynamics analysis (IDA) was performed on these frames under three sets of repeated ground motion records. Based on the IDA curve, life safety (LS) performance level was considered as the main guideline to develop the fragility curves. The maximum inter-storey drift percentages at each storey level, for all frames and location of plastic hinges for each frame, were clearly determined through IDA. From the fragility curve results, the probability of reaching or exceeding the life safety performance state was determined. The regular frame showed the lowest probability as compared to other frames. Therefore, it is known that the building configuration of frames affects the building’s seismic performance, and thus it should be considered in the building’s seismic design.
