摘要
采用非线性有限单元法,利用ANSYS程序分析钢管压弯构件的极限承载力。在此基础上,分析初始缺陷、长细比及两端作用不等弯矩等因素对该类构件稳定承载力的影响。
In this paper, the ultimate load of tube beam-columns was analyzed by the methods of nonlinear finite element and ANSYS program. The influences of initial imperfection, slenderness ratio and unequal end moment on the stability capacity of tube beam-columns are investigated by using the results of nonlinear finite element analysis.
