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,導出了彈塑性有限變形率形式的廣義變分原理
However , the analyses of suspension bridge structures are still preferred by finite displacement analysis based on 2d ( two - dimensional ) or spatial skeleton approximate models 但大跨度懸索橋的分析至今還局限于用平面或空間骨架近似模型。
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 本文以有限位移理論為基礎,將現(xiàn)今通用有限元分析軟件與懸索橋內(nèi)力分析結合,探尋一套懸索橋有限元建模、計算的數(shù)值方法,以滿足工程建設要求。
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:分析重慶北碚朝陽吊橋在1992年8月高溫時,使固定支座破壞的原因,在現(xiàn)場調(diào)查和結構內(nèi)力分析基礎上,提出了將固定支座改為有限位移橡膠墊板支座方案,實踐證明是可行的
