Abstract
The choice of input ground motion in the evaluation of the seismic response is a complicated task. The ground motion parameters need to be determined by the scope of the analysis and the potential damage of new or existing buildings. This work presents nonlinear dynamic analyses on reinforced concrete frame widely present in China. Input ground motions contain uncertainty and variability comes from both natural recordings and modified ones. Magnitude scaling and spectrum matching are used in this study. Nonlinear dynamic analyses of reinforced concrete buildings simulated by SeismoStruct and OpenSEES are carried out to evaluate the seismic response. Findings from the investigation indicate that spectrum matching is generally stable and shows good performance in response prediction.
