利用能力谱法对结构地震损伤评估简化方法

A simplified approach for seismic damage assessment based on capacity spectrum method

利用推覆(push-over)分析下的钢筋混凝土结构(构件)力-变形曲线计算结构(构件)的损伤指数,并将该法和能力谱方法结合,建立了一种简单实用的结构损伤评估方法.最后,将算例结果与时程分析法结果进行了对比,验证了该法的有效性.

The force-deformation curve of a reinforced concrete structure (member) with push-over analysis is used to compute its damage index. Thus, a simplified and practical method is established for seismic damage assessment in combination with capacity spectrum method. Finally, the presented approach is compared with the results using time-history analysis, and the effectiveness of this approach is verified with the help of numerical examples.
