Abstract : in this paper , the generalized variational principle of ela stic and plastic problem with finite displacement is derived by means of semi - in verse method 文摘:利用半反推法,导出了弹塑性有限变形率形式的广义变分原理
However , the analyses of suspension bridge structures are still preferred by finite displacement analysis based on 2d ( two - dimensional ) or spatial skeleton approximate models 但大跨度悬索桥的分析至今还局限于用平面或空间骨架近似模型。
Combining the all - function fem software and the stress analysis of suspension bridge , this paper presents a numerical method based on the finite displacement theory for model building and calculating the inner force of suspension bridges , which meets the demands of engineering construction 本文以有限位移理论为基础,将现今通用有限元分析软件与悬索桥内力分析结合,探寻一套悬索桥有限元建模、计算的数值方法,以满足工程建设要求。
Abstract : the paper analyses damaging causes for fixed support of chongqing beibei chaoyang suspension bridge in high temperature in august 1992 . it put forward the idea for changing fixed support into finite displacement supper support based on site and analyses for structural intemal force . it is practical for engineering 文摘:分析重庆北碚朝阳吊桥在1992年8月高温时,使固定支座破坏的原因,在现场调查和结构内力分析基础上,提出了将固定支座改为有限位移橡胶垫板支座方案,实践证明是可行的
