钢筋混凝土框架-剪力墙抗震性能研究

A Study on Earthquake-Resistant Behavior of R. C. Frame-Walls

本文运用矩阵位移方法,经对三榀框架-剪力墙进行弹塑性电算分析及与有关试验比较,说明框剪结构屈服后,剪力墙卸载,框架变形加大,最大剪力层转移,层间剪力明显增加。如不考虑这一影响,将会偏小估计框架的荷载效应。

By the method of matrix displacement and compared with the test results, an elastic-plastic analysis of three R.C. frame shear wall models has been presented. It is shownthat after the yielding of frame-walls, shear wall will transfer some load to frame, andthe frame displacements will be increased. At the same time, the frame floor on whichthe maximum of shear act will be shifted, and the shear acting on frame will be in-creased distinctly. It is pointed out that if the influence mentioned were ignored, theload effect of the frame would be underestimated.
