【摘要】 以全焊接钢结构梁柱节点为研究对象,利用ABAQUS平台自编热源子程序DFLUX,基于顺序耦合法对残余应力场分布情况进行动态模拟,通过残余应力基础上的拟静力分析结果与试验结果的对比分析,表明焊接模拟的必要性和对拟静力分析结果的影响。更多还原

【Abstract】 In this paper,a steel beam-column connection of full welding is chosen as the research object,the heat source subroutine on AB AQUS platform is edited by the author,the distributions of residual stress field is simulated dynamically.Through the comparison between the results of quasi-static analysis and the experimental results,the necessary of the welding simulation and the influence of the quasi-static analysis results can be indicated.更多还原
