柱面索拉网壳是一种混合形式的单层网壳,常用于玻璃采光顶支承结构.本文讨论了这种结构的静力特性,比较了在满跨荷载作用下单层柱面索拉网壳和普通柱面网壳的位移及钢杆件应力.然后计算了各种参数(钢杆件截面、索截面、索初始预应力、长跨比、矢跨比)对柱面索拉网壳结构静力特性的影响.计算结果表明:单层柱面索拉网壳的静力特性优于单层柱面网壳;单层柱面索拉网壳的位移随着钢杆件截面和索截面的增大而减小;一定的初始预应力对索拉网壳的静力特性影响很大;随着矢跨比增大,柱面网壳的位移先增大后减小;结构的位移和钢杆件应力随长跨比的增大而增大.
Cylindrical Sora shelled is a hybrid form of single-layer reticulated shell, commonly used in glass lighting overhead support structure.This paper discusses the static characteristics of this structure, compared with the full-span load single-layer cylindrical thimble The displacement of reticulated shell and ordinary cylindrical reticulated shell and the stress of steel bar were calculated.And then various parameters (steel bar section, cable section, cable initial prestress, long-span ratio, The results show that the static characteristics of single-layer cylindrical SRS are better than that of single-layer cylindrical reticulated shells. The displacement of single-layer cylindrical SRS varies with the cross-section of steel members and As the ratio of sag to span increases, the displacement of cylindrical reticulated shell first increases and then decreases. The structure of the Displacement and steel member stress increases with the span ratio increases.
