| 摘 要： | 采用空间纤维模型作为宏观分析工具,提出了一个考虑刚度退化、强度退化和捏拢效应等特征的剪切力-变形滞回模型,对采用3种不同端部约束的剪力墙模型进行了反复加载非线性模拟分析,取得了与试验结果吻合的计算结果,证明所采用的计算方法能有效地模拟剪力墙构件在不同端部约束条件下的抗震性能和破坏机理.然后利用该分析方法对一系列不同端部约束形式剪力墙进行分析比较,来进一步探求端部约束对剪力墙抗震性能的影响规律. |
| 关 键 词： | 剪力墙 纤维模型 抗震性能 剪切滞回模型 滞回曲线 |

| Abstract: | The space fiber model is used as a macro analysis tool and a shear force-deformation hysteresis model considering stiffness degradation and strength deterioration and pinching behavior is presented.The shear wall models with three different boundary restraints under reversed lateral loads are analyzed using this model;and the calculated results are verified to be in close agreement with the experimental ones;and it proves that the presented method can produce an efficient measure to analyze the seismic behavior and the failure mechanism of the shear wall with different boundary restraints. Then a series of shear walls with different boundary restraints are analyzed and compared by using this method so as to search for the further rule that the different boundary restraints influence the seismic behavior of the shear wall. |
| Keywords: | shear wall fiber model seismic behavior shear hysteresis model hysteresis curve |
