采用自编的双重非线性壳体有限元程序ＤＮＳＦＥＭ，分析了四边简支板和箱形截面钢短柱的滞回性能，得到了箱形截面钢短柱的翼缘板在强震条件下的宽厚比限值。
The double nonlinear shell finite element program DNSFEM was used to analyze the hysteretic behavior of four-legged simply supported and box-section steel short columns. The flange plate with box-section steel short columns was obtained under strong earthquake conditions Aspect ratio.
