| 摘 要： | 对钢框架内嵌竖缝剪力墙结构进行研究，考虑混凝土材料非线性的影响，通过非线性有限元程序，分析钢框架内嵌竖缝剪力墙结构在水平荷载作用下的力学性能．结果表明：竖缝剪力墙在加载过程中，首先在竖缝附近发生开裂，主要分布在缝间墙上，并以细小裂缝为主，这是由于竖缝剪力墙承担了自身开裂膨胀而产生的约束轴力．从竖缝剪力墙的应力和裂缝分布图可以得出，剪力墙的变形主要是以弯曲变形为主，缝间墙的变形类似于壁柱．在加载过程中，竖缝剪力墙刚度下降缓慢，利于与钢框架共同工作，适合在抗震区使用．

| Abstract: | Aimed at the behavior of steel frame-reinforced concrete infill slit walled system,the material nonlinear behavior of concrete was considered,and steel frame-reinforced concrete infill slit walled system was analyzed by FEA.It was found that the cracks occurred around the silts in the loading process.For wall bears the constrained axial force which is generated by expansion of concrete,a lot of small cracks were distributed in wall.From the stress and crake figure of silts-wall,the deformation of shear wall... |
