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
最后，运用ansys通用有限元程序的beam189单元，引入初弯曲和残余应力的影响，用考虑几何和材料双重非线性的有限元求解格式求得箱形柱在不同轴力和弯矩比例作用下的弹塑性极限承载力，通过对十几个不同截面尺寸构件在不同长细比下的承载力计算，发现在轴力p远大于弯矩m时，构件将是平面外失稳控制，而当轴力p远小于弯矩m时，构件则以平面内失稳为主。
