受损剪力墙的非线性分析

砼剪力墙一种有效的抗偶力构件，成功地应用于各种抗震结构。但剪力侧向刚 大，地震时所承受的地震作用也较大，因此，在强地震作用下时常受损。本文作者采用钢筋砼非线笥有限元程序，对受损砼剪力墙进行了计算分析。计算模型考虑了钢筋和砼之间粘结－滑移，任意反复加载过程，砼开裂和裂缝闭合，裂缝宽度模拟。最后与试验结果进行了对比分析。

Nonlinearanalysis of damaged concrete shear walls

Concrete shear walls have been used successfully in many seismic structures for last thirty years to meet the resistance to lateral forces.As the concrete shear walls are more rigid in lateral than other members in a structures,they are assigned more lateral forces and usually damaged in earthquakes.The damaged concrete shear walls are calculated and analyzed by reinforced concrete nonlinear finite element program in this paper.The bond between steel and concrete,random and cyclic loads procedure,concrete cracking and cracks closing are considered in the program model.Also the experimental results are compared in this paper.
