基于能力谱的高架车站地震易损性分析

地震易损性分析是一种评估震害损失的方法。采用Pushover能力谱分析法对高架车站结构进行抗震性能研究，考察了层间位移角和塑性铰的出现机制，得到了易损性曲线和易损性矩阵。结果表明，高架车站结构实例在各级地震作用下主要发生轻微损坏或较小概率的中等程度损坏，层间位移角符合性能设计要求。分析所用的方法简易可行，结果可供参考。

Analysis on Seismic Vulnerability of Elevated Stations Based on Capacity Spectrum

The analysis of seismic vulnerability is a method for assessing seismic damage. The seismic performance of elevated station structures is studied by using the Pushover capacity spectral analysis method. The emergence mechanisms of inter-story displacement angle and plastic hinge are studied to obtain the vulnerability curve and vulnerability matrix. The results show that the elevated station structure example suffers mainly minor damage or a small probability of moderate damage under all levels of seismic action, and that the inter-story displacement angles meet the performance design requirements. The method used is simple and feasible, and the results are available for reference.
