型钢桁架混凝土剪力墙的非线性有限元分析

Nonlinear Finite Element Analysis of Steel Truss Reinforced Concrete Shear Walls

利用有限元分析软件ANSYS进行了型钢桁架混凝土中高剪力墙和低矮剪力墙的实体有限元分析,得到了型钢桁架混凝土剪力墙在顶部水平荷载单向加载作用下墙体的变形性能,裂缝出现、发展、分布形态,试件破坏的形态,水平荷载-位移骨架曲线,以及试件开裂荷载、极限荷载、初始刚度、屈服刚度等力学指标。结果表明,有限元模型分析结果与试验结果吻合很好,可为此类构件的受力性能分析提供一种有效手段。

Using the finite element analysis software ANSYS, authors analyzed the reinforced concrete mid-rise and low-rise shear wall embedded with shape steel, and got the wall deformation, as well as the mechanics indexes, such as deformation properties, cracks＇ appearance, development and distribution shapes, the specimen＇s damaging patterns, the horizontal load and deformation skeleton curves, the specimen＇s cracking load, ultimate load and initial stiffness and yielding stiffness and so on. The results show that an effective method to perform the mechanical property analysis on this kind of structural components which are in good agreement with the test results is provided.
