砼剪力墙作为一种有效的抗侧力构件 ,成功地应用于各种抗震结构。但剪力墙侧向刚度较大 ,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性有限元程序 ,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
Concrete shear wall as an effective anti-side force components, successfully applied to a variety of seismic structures. However, the lateral stiffness of the shear wall is relatively large and the earthquakes subjected to the earthquake are also large in magnitude. Therefore, they are often damaged under strong earthquakes. The author uses the nonlinear finite element program of reinforced concrete to calculate and analyze the damaged concrete shear wall. The calculation model takes into account the bond-slip between rebar and concrete, arbitrary repeated loading process, concrete cracking and crack closure, and crack width simulation. Finally, the test results were compared
