薄壁箱梁的约束扭转分析

On the Constrained Torsion of the Thin Wall Girder with Box-shape Cross Section

采用文 [1 ]建立的三维退化梁单元并结合三维退化板单元 ,分析了薄壁矩形箱梁的约束扭转问题。文中的计算方法结果表明 :该方法引入的几何假设少 ,力学概念清晰 ,计算省时省力 。

With the 3-d deteriorated girder and pla te elements presented in[1],the paper analyses the constrained torsion of th e thin wall girder with box- shape cross section.Being the less geometric hypothesis and simple conceptual,th e method shows the high efficiency and good precision.
