| 摘 要： | 本文建立了压弯构件在各种受荷失稳模式下极限荷载分析的统一模型并编制了相应的数值计算程序。在每种失稳模式下都和有关实验结果(包括本文作者实验结果)进行了比较,证实了本文程序的极好的可靠性。利用本文程序进行了计算机模拟系列计算,分析了初始缺陷对压弯构件(尤其是对双向偏压构件)极限荷载的影响特性。

| Abstract: | A general model for the ultimate carrying capacity analysis of beam-columns has been established, and its numerical procedure has been programed in this paper. The theoretically calculated values of each buckling mode are compared with the experimental results to verify the validity of this program. With the help of this program, detail discussions of the effects of initiai deflection and residual stress on the behanior of beam-columns, especially on the biaxially loaded beam-columns, have been conducted. |
