摘要:

针对现行的结构抗震设计规范没有考虑双震中地震动对结构性能的影响问题,引入同时反映位移超越及能量耗散影响的双参数损伤模型进行结构损伤评估,可以更好地反映结构构件在不同类型地震动作用下的损伤发展规律.比较4种构件的双参数损伤模型,并对其中一种模型进行改进.对汶川地震中一典型的9层框架结构进行三维非线性地震响应分析,研究结构损伤规律.分析结果表明,结构主要的损伤积累发生在第一次主震中.结合现行抗震设计规范,提出一种直接基于目标损伤指标的结构抗震设计方法,通过一简单算例验证了该方法对大震作用下结构抗震设计的适用性.

Abstract:

The obvious dual-epicenter was not considered in the present seismic design code. An appropriate damage model should take both the damage caused by dissipated energy and displacement overpass into consideration in order to evaluate the progress of structural damage. Four damage models were described, and one of which was improved. Comparisons of the damage models were made in three-dimensional nonlinear dynamic analysis of a 9-storey reinforced concrete structure subjected to a real Wenchuan earthquake excitation. Results showed that damage in the structural members increased mainly in the first shock. A performance-based approach based on target damage index was proposed and verified in conjunction with present seismic design method for high level earthquake.
