A Comparative Study of the Traditional Performance and the Incremental Dynamic Analysis Approaches ( IDA)
Abstract eng: In this study, the applicability of different load patterns in traditional pushover for seismic response assessment is investigated. At first Cornel UPSHA approach is used for estimating response spectra with probability of exceedance PE=10% and a time histories compatible with those of estimated response spectra were determined to be used in IDA method. Following this, three steel MRF frames (3, 9 and 15-story) according to IBC-ASD have been selected and designed, then the frames loaded under different load patterns (inverted triangular, uniform and first mode-based) that is frequently used in traditional pushover analysis methods. The outputs of the structural analysis, in the forms of, story shear versus story drift ratios of upper, middle and lower portions of structural heights were depicted and compared with those of IDA method and standard error of selected frames were calculated.
