| 摘 要： | 通过空间有限元分析，对影响其力学性能的高跨比、宽跨比、钢腹板的波纹形状及其板厚等几何参数进行了敏感性研究。结果表明，减小高跨比和宽跨比、增大波形钢板的折叠角度、增加水平面板宽度以及增大钢腹板厚度可以改善结构在偏载作用时的受力性能。

| Abstract: | With the finite element method, several geometrical parameters influencing its mechanical performances were analyzed. These parameters include the ratio of height and span, the ratio of width and span, corrugation configuration of steel web and the thickness of steel web. The results show that decreasing the ratio of height and span, the ratio of width and span, the configuration angle, horizontal panel width and the thickness of steel webs can improve its mechanical performances under eccentric loading. 2 tabs, 9 figs, 8 refs. |
