摘要
彩色压型钢板(以下简称彩板)波形拱壳结构在半跨偏载作用下容易发生折曲屈曲破坏,其极限承载力较低。为了提高这种结构在半跨偏载作用下的极限承载力,作者提出了一种斜拉式彩板波形拱壳结构。通过对这种新型斜拉式结构进行有限元内力和稳定分析,重点研究了斜拉杆的纵向有效影响范围,并结合工程实例给出了理论计算结果。
TIs paper Presents the theoretical and experimental investigation of an arch roof structure wb corrugated thin-walled section, which is strengthened by adding tensile ho or tensile cables. It is found from numerical studies that the ultimate load-carrying capacity of the structure wb tensile bars or tensile cables is higher than that without tensile ho or tensile cables by nearly 100% ill the case of a uniformly distributed load on half span. The Iongitudinal spacing of the tensile bars or tensile cables along the structure is determined by finite element method. A numerical computation is completed in the case of an ed roof structure with span of 36 m.
