The paper is based on an arcuated built - up system bridge - zhongshan no. one bridge to be built in guangzhou, adopts the large universal finite element programme ansys, takes spatial action among members into account, establishes a three - dimension finite element model, and discusses the following several aspects : firstly, when three - dimensional finite model of a complicated bridge is founded, a beam - lattice method is a kind of applied and effective spatial analysis method, which is used to analyze superstructures of a bridge
本文以廣州市中山一橋為背景，採用大型通用有限元程序ansys ，考慮構件間的空間相互作用，建立了三維的有限元模型，重點對以下幾個方面進行深入探討：首先，在對復雜的橋梁結構進行三維的有限元模型建立時，梁格法是分析橋樑上部結構比較實用而且有效的空間分析方法。 -
The effect of different sizes of sections, modes and values of residual stresses are studied. through the analysis, the conclusion is arrived at that the universal slenderness ratio should be used to better correlate the stability of box section beams with the member length instead of the out - of - plane slenderness, and the stability coefficient is taken to be 1. 0 for practical used box girder. then, the elastic critical loads of box section beam - columns are obtained based on the gjelsvik theory, and the relationship between axis force p and moment m is given
最後，運用ansys通用有限元程序的beam189單元，引入初彎曲和殘余應力的影響，用考慮幾何和材料雙重非線性的有限元求解格式求得箱形柱在不同軸力和彎矩比例作用下的彈塑性極限承載力，通過對十幾個不同截面尺寸構件在不同長細比下的承載力計算，發現在軸力p遠大於彎矩m時，構件將是平面外失穩控制，而當軸力p遠小於彎矩m時，構件則以平面內失穩為主。
