框架结构中填充墙平面内外地震作用效应
|
摘要
框架填充墙结构中填充墙的地震破坏甚至倒塌是需要深入研究的问题,本文首先介绍了能考虑平面内和平面外相互作用的改进填充墙模型,能判断框架填充墙结构中填充墙的破坏状态,以及填充墙与框架之间的相互作用;然后,基于Open Sees有限元软件,进行罕遇地震作用下空框架和框架填充墙两有限元模型的三维非线性数值模拟,对比分析两者塑性铰区域纵筋应变、层间位移以及加速度峰值反应的差异,进而深入研究了填充墙在框架填充墙结构中的作用及原因分析。
The seismic damage even to be collapsed to the infilled walls in RC frame infilled wall structure is the key issue that needs to be studied in detail. In this paper,firstly,the improved infilled wall model,which can consider the interaction between in-plane and out-of-plane( IP-OOP) is introduced,in which the damage state of infilled walls as well as the interaction between RC frame and infilled walls can be judged. Secondly,based on the finite element software Open Sees,the 3D nonlinear numerical simulation of two finite element models i. e.-RC frame without infilled walls and RC frame with infilled walls,are performed under rare earthquake,then,differences of both plastic hinge zone's steel strain,drift and acceleration response are analyzed and compared. Finally,the infilled walls effects in RC frame infilled wall structure and reason analysis are studied in detail.
