摘 要: 提出一种新的板壳单元,建立以结点位移为未知量的平衡方程组,组装得到的整体刚度矩阵为稀疏带状矩阵.与常规试载法相比,所需存储容量小,计算速度快.该方法已在实际工程中得到了应用,并取得令人满意的结果. A new type of shell element is presented to form an equilibrium equation with unknown node - displacements. The equation is a sparse and banded matrix requiring less computer storage and computing time in comparison with the traditional trial load method, and has been applied to analyze the stresses of Xiaowan arch dam and the result has been proved sat-isfactoryly in practice.
