| 摘 要： | 求解了承受双向偏心荷载任意开口薄壁截面的弹性平衡方程,获得此类柱适用于任何边界条件的弹性解析解。应用有限元法发展了任意开口薄壁截面柱在双向偏心荷载下的弹性理论,并编制了模拟计算程序,对有限元弹性解和弹性解析解进行了比较,理论计算和实验结果吻合较好。

| Abstract: | The exact solution of the biaxially loaded elastic column with any
open-section is obtained, which is applicable for any combination of boundary condi-
hons, and the elastoplastic theory of the biaxially loaded column with open cross-section
is developed with Finite Element Method, on which a computer program is made to cal-
culate the ultimate load-carrying capacity of the column, and the computer program is
checked by comparing the elastic exact solution with the finite element. The tested results
are compared with the calculated one, and it is found that the comparison is in reasona-
ble agreement, especially for the maximum load-carrying capacity. |
