摘要
本文基于连续化模型,将框筒视为边缘加筋的平面应力平板组合结构,巧妙地变换框筒顶部的自由端边界条件,通过求解双调和方程得到了方形简体结构的弹性力学精确解,其主要工作是采用力法思想将框筒变为单块板的平面应力问题,再求出其级数形式的解.文中给出的级数解收敛快,能正确反映剪力滞效应和角柱效应,通过比较表明,以往的能量变分和有限条解均与之基本吻合,且本文解给出了更明显的剪力滞效应.
In this paper, the shear-lag effect of the tall frame-shear wall structures is studied with the plane stress theory. The methods and the results given in this paper are very useful to engineers and designers.
