结构在地震作用下的损伤评估方法

Damage Assessment Techniques for the Structure under the Seismic Motion

建筑结构应该能够承受一定地震运动的作用,同时也应该允许其产生一定的损伤.对于结构在地震作用下的损伤评估有多种的方法.本文将分别对从累积损伤方面、变形方面、变形和累积损伤的总和方面、刚度退化方面得到的损伤模型的特点进行评述.

The structure must be survived in a certain seismic motion , there are several methods to predict the state of damage of the structure after the seismic. The purpose of this paper is to review the concept which have been used in damage prediction , four types of techniques have been considered. One is based on the cumulative damage , the other is about the degradation of the stiff of the structure , the next is based on the maximum deformation and cumulative damage, the last is based on the maximum deformation, A number of available damage index are discussed for their applicability in seismic damage evaluation.
