Comparative research on method to calculate overall stability of full - web type axially compressed member 钢结构实腹式轴压构件整体稳定性计算方法的比较研究
In active code for design of steel structures , axially compressed members are calculated not as torsional - flexural buckling but as flexural buckling with equivalent slenderness ratio , residual stress and initial geometry imperfection are also taken into account as flexural buckling 我国现行钢结构设计规范( gb50017 )采用换算长细比的方法将弯扭失稳等效为弯曲失稳,其残余应力和初始几何缺陷均按弯曲失稳考虑。
Then according to the compare and analysis of simulative results , theory calculation and testing data , the feasibility of simulating the axis compressed member is verified by the finite element method . it can be extended to the finite element simulation of the member under eccentricity compression 通过对计算结果与理论计算值、实验测试数据的比较分析,验证了应用有限元法模拟轴心受压构件的可行性,并将其推广到偏心受压构件的有限元模拟中。
