【摘要】 利用变分原理求解T形截面短肢剪力墙的剪力滞系数和构件变形,讨论不同几何参数和荷载形式对剪力滞效应及变形的影响。用有限元法对翼缘板的纵向应力分布情况进行分析,并与初等梁理论及变分原理的计算结果进行比较,揭示了剪力滞效应对构件侧移刚度的影响程度。更多还原

【Abstract】 The shear-lag coefficient and deformation of T-shaped short-leg shear wall are solved based on variation principle,various parameters and loading forms which may impact the shear-lag are discussed.The distribution of longitudinal stress in the flange is analyzed using FEA method.The deformation and stress according to primary beam theory,variation principle and FEA method are compared,and their impact on the stiffness of the short-leg shear wall is discussed.更多还原
