混凝土框架结构强柱弱梁实现机制研究分析

The strong column weak beam implementation mechanism analysis of the concrete frame strcture

地震后资料显示,框架结构多为"强梁弱柱"破坏,即框架柱破坏严重,框架梁震害较轻。针对该问题,本文以一实际工程为例,应用静力非线性分析方法分析框架结构在地震作用下的破坏机制,并讨论增大柱弯矩增大系数及柱截面积对混凝土框架结构破坏机制的影响。

According to the information after the earthquake,the damages of most frame structure are weak column strong beam.This paper takes a practical for example,Analyzes the failure mechanism of the frame structure under earthquake using static nonlinear analysis,and discuss the influence of concrete frame structure failure mechanism that changing steel strength grade,and the moment magnifying factors at column ends.
