摘　　要：以T形短肢剪力墙为例,考虑剪切滞后的影响,提出异形截面肢多垂直杆模型。利用变分法推导出空间单元刚度矩阵。针对实际中的弯剪变形相关,对刚度矩阵进行了修正,并进行了地震荷载的动力反应分析。通过比较修正前与修正后的计算结果,表明经过修正后的刚度矩阵使短肢剪力墙结构的性能更符合实际情况。Considering the effective influence of shear-lag, special-section multi-component model was put forward in this paper for example T-shaped short-leg shear wall. The spatial stiffness matrix of element was derived from variational principle, which was corrected because of the flexure-shear deformation correlation. From the computed result, it can be found that performance of short-leg shear wall structure with corrected matrix is realistic.
