多层滞后框架结构变形能力的抗震可靠性分析

Earthquake Resistant Reliability of Deformation Capacity for Multistorey Yielding Frames (Based On Bar--storey Model)

本文提出了基于层间-杆系模型的多层滞后框架结构,在强烈地震干扰下,结构构件和结构体系变形能力抗震可靠性的计算方法。克服了目前习用的基于层间剪切模型的抗震可靠性计算方法中,不能进行结构构件变形能力可靠性分析,以发现结构中的薄弱环节,结构体系变形能力可靠性计算比较粗糙,近似性大的缺点。

This paper presents a method calculating the earthquake resistant reliability of deformation capacity for multistorey yielding frames based on the bar-storey model. The reliability of deformation capacity for structural members may be calculated by the method, which can not be calculated by method based on shear-storey model. We can find out the weak part of the structures with the help of the calculating results.
