ABSTRACT
The seismic diagnosis of an existing building, subjected to strong repetitive earthquakes specific for Romanian locations is performed based on its nonlinear behavior. The objective of this study is to evaluate if the modeling and analysis techniques are adequate to predict the inelastic behavior of damaged buildings exposed to consecutive strong earthquakes. The evaluation is based on nonlinear time-history analysis. A 10-story reinforced-concrete (R-C) frame, specific for tall buildings located in Romania, designed to fulfill the Romanian seismic requirements is chosen as case study for simulations using IDARC2D. Several nonlinear analyses have been performed for a scenario of earthquakes. The results highlight the diagnosis-based seismic nonlinear behavior of the structure under repetitive seismic events.
