剪力墙多垂直杆单元模型的改进及应用
|
摘要
对目前多垂直杆单元模型考虑剪切变形的三种方法进行了探讨和对比,提出了一种更为合理的刚度矩阵形式。结合钢筋混凝土拉压滞变模型和剪切滞变模型,可对剪力墙进行非线性分析。最后,提供了一个算例,并与试验结果比较,表明该模型具有较好的计算精度。
Three methods for calculating shear deformation in the multi-vertical-truss-element model are discussed in detail and a comparison is made. A more reasonable derivation process of the element stiffness matrix is put forward. Combined with hysteretic axial model and hysteretic shear model, nonlinear analysis of shear wall is performed. An example is calculated and compared with test results, which shows that the model offers results with good accuracy.
