| 摘 要： | 在试验研究的基础上,运用有限元分析程序ANSYS对钢筋混凝土无洞叠合墙体进行非线性分析。通过建立合理的力学模型,模拟分析了叠合墙体的裂缝开展与分布、承载能力、破坏模式等方面的特点和规律,并与试验结果进行对比验证。有限元值与试验值吻合较好,说明本研究在进行有限元分析时所选择的计算模型、材料本构关系、破坏准则等较为合理的,可以应用于叠合剪力墙的进一步分析研究,弥补试验研究的局限性。剪式支架能使钢筋混凝土叠合剪力墙的预制部分与现浇混凝土形成整体,共同工作,承受外部荷载。

| Abstract: | Based upon the experimental studies,nonlinear finite element analysis on composite reinforced concrete shear wall without opening by using finite element software ANSYS was comprehensively studied.Based on the reasonable mechanics models and methodologies,the seismic behavior was researched for the wall structure on the horizontal loading test.The crack expansion,failure mode were discussed.The prefabricated parts and the cast-in-situ concrete parts of the composite reinforced concrete shear walls could work together in coordination very well under loading. |
