根据震后结构破坏状态反演地面运动参数研究

STUDY ON INVERSE OF THE GROUND MOTION PARAMETERS ACCORDING TO THE POSTEARTHQUAKE DESTRUCTION STATE OF STRUCTURE

摘要:

提出了一种根据地震后的结构所呈现的破坏状态,运用结构破坏反演技术来确定地面运动参数的新方法。以钢筋混凝土框架结构为例,在对地震作用引入一些基本假定后,建立了根据震后结构破坏状态反演地面运动参数的数学模型;并进一步提出了一种前行步步比对法,给出了若干算例。结果表明该方法是可行的。最后还提出了进一步研究要解决的若干问题。

Abstract:

A new method of determining ground motion parameters according to the destruction state of structure after earthquake, which using the inverse technology, is raised. The mathematical model of inversing ground motion parameters for reinforced frame is found with introducing some assumptions about earthquake effect. One method that was called Forward Step-by-step Comparison is raised. At last three examples are given in this paper,and some questions for further studing are put forward.
