摘要
应用最小势能原理中的有限元分析法,选择单元位移函数,并计算单元的应变能,对有竖向挠度和剪切变形的梁的单元刚度矩阵进行了推导,从而为实际计算应用提供了方便。
In this paper, it uses finite-element method of minimum potential energy principle to deduce specific stiffness matrix of girder through selecting displacement function of element and calculating strain energy, which have vertical flexibility and shearing deformation, to simplify actual calculation.
