摘要
应用有限元对格栅刚架框的斜撑杆的不同布局及其扭转刚度进行了分析计算 ,并对部分模型进行了实验。结果表明 ,斜撑杆的布局形式对结构的抗扭性能有明显的影响 ,合理的布局不仅明显提高了结构的抗扭刚度 ,也降低了其扭转工况下的应力水平。
The different layouts of slant beams in hollow box girder framework and their torsion stiffness are calculated with the finite element method in this paper.Some of the real models are also tested correspondingly.Both analytical and experimental results indicate that the layout of slant beams has significant influence of the structural torsion behavior and some of the layouts can cleavly improve the structural torsion strength.
