| 摘 要： | 通过分析指出了拱式转换层板厚对结构受力性能的影响.结果表明,上、下弦杆的最大弯距和最大剪力随着上层转换层板厚的增大而增大；随着下层转换层板厚的增大,上弦杆的最大弯距和最大剪力明显增大,而下弦杆的最大弯距和最大剪力不断减小；随着上、下层转换层板厚的增大,斜腹杆的最大轴力不断增加；竖腹杆的最大轴力随着上层转换层板厚的增大而增加,随着下层转换层板厚的增大而减小.

| Abstract: | The influence of plate thickness of arch transfer floor on structure behavior is analyzed.Results show that the maximum bending moment and shearing force of spandrel chord can increase with increase of upper plate thickness.With the enlargement of lower plate thickness,the maximum bending moment and shearing force of upper chord increase obviously,whereas lower one changes smaller.The maximal axial force of diagonal web member changes greater with increase of upper and lower transfer floor thickness.The maximal axial force of vertical web member shows accordance increase with thickness of upper transfer floor.However,it presents a decrease with increase of lower floor. |
