| 摘 要： | 根据具有剪切破坏特征的异型柱的试验现象，本文提出一种抗剪全过程分析计算模型。在该模型中，将异型柱的总变形分为剪切变形和弯曲变形两部分，并分别采用软化桁架模型和截面网格模型进行计算。将计算得到的剪切变形和弯曲变形叠加即为构件的总变形，而软化桁架模型分析结果给出构件抗剪强度及剪切应力变化过程，由此得到构件的荷载-位移全过程曲线。计算结果和试验结果的对比符合良好。

| Abstract: | According to the experimental phenomena of special-shaped section columns failed with shear, in this paper a model is presented to compute the loading-deformation full course curve. In this model, the total deformation is divided into shearing deformation and bending deformation, which are computed using the softened truss model and the sectional fiber model respectively. Satisfactory agreement between computational and experimental results shows the effectiveness of the proposed model. |
