FINITE ELEMENT ANALYSIS ON BUCKLING OF ARCH BY THE DEGENERATED 3-D CURVED BEAM ELEMENTS

摘要

摘要: 在三维块体等参元及１６结点相对位移板壳元的基础上，引入梁的基本假定，考虑几何非线性，构造出三维退化曲梁单元，计算了梁、拱线弹性屈曲临界荷载．

Abstract: Based on 3-D iso-parametric element and the plate shell element of relative displacement and combined with beam assumption, we proposed the degenerated 3 dimensional curved beam element with geometrical nonlinearity, which can be used for analysis of critical load of linear elastic buckling of beam and arch.
