Abstract:To investigate the damage assessment of the high-rise RC building structures under earthquake, a method of vulnerability curves based seismic damage assessment was used, establishing the damage index which was based on the maximum inter-story drift ratios. The vulnerability curves of mega-frame structures were constructed by incremental dynamic analysis for its damage assessment. It is demonstrated that the used method of damage assessment for mega-frame structures is simple in calculation as well as effective in evaluating the damage extent for different seismic intensity indices, and could provide reference for estimating seismic fragility analysis and rehabilitation after earthquake.
Keywords:mega-frame structures; seismic damage assessment; incremental dynamic analysis; the maximum inter-story drift ratio; vulnerability curve
