| 摘 要： | 根据短肢剪力墙结构的受力和变形特点，对多竖直杆模型进行了改进，建立了截面位移模型，摒弃了杆模型平截面假定的限制，有效地考虑了剪滞效应和翼缘的影响。利用变分原理导出了T形短肢剪力墙的空间单元刚度矩阵，研制了弹塑性时程分析程序，并输入三种不同的地震动进行了算例分析，计算结果表明，短肢剪力墙结构抗震性能较好，适合于在地震区推广使用。

| Abstract: | According to mechanical properties and deformation feature of short-leg shear wall, multi-component model is improved by introducing the cross section displacement function which considers the effect of shear-lag and flange plate, and thus it is free of the restriction of plane cross section assumption. Space stiffness matrix is derived by variational principle and program of elastoplastic time-histroy analysis is developed. Finally, an example is calculated by inputting three kinds of earthquake waves. The results show that short-leg shear wall is possessed of relatively good earthquake resistance performance. So it is worthy of using in earthquake zones. |
