Abstract

There are considerable debates in the technical literature regarding to effect of earthquake duration on damages in the structures. If duration of strong-motion is important, care must be taken that in design and evaluation of structures should be used records with suitable duration. In this study, time-history analysis has been done on an 8-story steel moment frame building using 49 accelerograms with different duration. Primary effect of earthquake spectral amplitude is homogenized by scaling and adjustment of records using wavelets so that they have good match to target smooth response spectrum of Iran seismic code. Comparing correlation between duration and different damage measures reveal that although duration has no important effect on maximum response measures, checking other measures show that structural damages may increases subjected to longer duration earthquake.

Keywords : accelerogram, scaling, earthquake duration, time-history analysis, damage measures
