Abstract

Mass irregular structures have stories with effective mass more than 150% of effective mass of adjacent storey. Seismic response of mass irregular structures are assessed by consideration of SMRF structures with 4, 6 and 8 stories, which mass irregularity is applied separately by 1.4 and 2 times mass changes in top and two intermediate stories. Seismic response is achieved by applying Incremental Dynamic Analysis. Mean annual frequency and probability of exceedance in 50 years of performance levels are evaluated by applying PBEE framework. Finally understood which mass irregular structures response is related to location and number of stories with mass changes. Also, 150% limitation of mass change for definition of mass irregularity need more
study.
