Abstract

The collapse assessment of reinforced concrete (RC) structures is critical for evaluating their seismic capacity. In the past, the incremental dynamic analysis (IDA) method was used to assess the collapse. However, despite its accuracy, engineers avoid the IDA method because it is time-consuming. In this study, the authors used the method based on capacity spectrum method (CSM), which is more practical, to calculate the collapse limit and evaluate the seismic capacity of RC buildings. Finally, the authors compared the collapse limits evaluated by the CSM and IDA methods using observed and artificial ground motions. The results of both methods were in good agreement. In addition, it was found that the shape of the response spectrum affected the accuracy.
