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。
The corrugated arch shell structure of the color profiled steel plate (hereinafter referred to as the color plate) is prone to flexural buckling under the half-span partial load, and its ultimate bearing capacity is low. In order to improve the ultimate bearing capacity of this kind of structure under the semi-span partial load, the author proposes a kind of oblique-pull type color plate wave arch shell structure. Through the finite element internal force and stability analysis of the new type of oblique-pull structure, the longitudinal effective range of the diagonal pull rod is studied. The theoretical calculation results are given with engineering examples.
