摘要
本文选取剪跨比和弯扭比这两个影响平截面假定成立的主要参量,在截面层次上以截面应变误差分析作为平截面假定成立的定量判定依据,构件层次上以两种模型得出的柱顶侧向位移误差作为依据,对处于弹性阶段的L形柱平截面假定的适用性进行了探讨,得出了不同受力情况下平截面假定适用的最小剪跨比。
Span ratio and crankle ratio are selected in this paper, which influence the applicability of plane-section assumption in the analysis of L-shaped RC columns. According to the error analysis of strain of the section level and displacement on the member level, the range on the plane-section assumption in the elasticity analysis of L-shaped RC columns is studied. The minimal span ratio in the range of the plane-section assumption in the elasticity analy- sis of L-shaped RC columns with different loading cases is presented.
