| 摘 要： | 钢筋混凝土剪力墙的边缘约束情况是影响其抗震性能的重要因素,对于无边缘约束构件的既有剪力墙结构进行开洞改造,为验证改造后的结构的抗震性能,本文分别依据原有结构和现行规范设计、制作了10片开洞前、后的剪力墙模型,通过对其进行低周往复荷载试验,验证剪力墙开洞对结构抗震性能的影响,并验证了改造后的结构仅需进行简单的构造加固即可达到安全性能要求。

| Abstract: | The boundary element has an important influence on the seismic behavior of shear walls.In order to verify the seismic behavior of existing shear wall structures without boundary elements after retrofit,10 piece of shear walls with different opening cases designed by new and old codes were made and tested under the reversed cyclic quasi-static loading.The influence of the opening cases on the seismic behavior of shear walls is verified,and the safety of the retrofitted structure with simple constructional strengthening is proved. |
