摘　　要：提出并推导了钢筋混凝土梁剪压区剪切模量的简化折减系数,提出了非线性剪切变形的简化计算方法,采用三分段杆单元模型可对钢筋混凝土筒体结构裙深梁进行非线性分析,最后提供了两个算例,并与试验结果比较,表明方法的合理性。The simplified reduction factor of shear modulus in the shear-compression zone of reinforced concrete beam was put forward and derived in the paper, and the simplified calculation method of nonlinear shear deformation was also brought forward. Nonlinear analysis of the spandrel deep beams reinforced concrete tube structure＇s can be carried out based on the three-fragment-line-element model. Finally, two examples were calculated and compared with test results, which shows that the presented method is reasonable.
