| 摘 要： | 柱面索拉网壳是一种新型的玻璃采光顶支撑结构。讨论这种结构的动力特性,比较单层柱面索拉网壳和单层柱面网壳的自振频率及其相应振型。通过计算,分析长跨比、矢跨比、索截面、索初始预应力、钢杆件截面对柱面索拉网壳动力特性的影响。计算结果显示:单层柱面索拉网壳的动力特性优于单层柱面网壳;单层柱面索拉网壳的自振频率随着钢杆件及索截面的增大而增大,随长跨比的增大而减小。索的初始张拉力对索拉网壳的动力特性影响很大。

| Abstract: | Single-layered cylindrical cable-beam shell is a new support structure of glass roofs, this article discussed the dynamic properties of this structure, and self-vibration frequency and its corresponding mode shapes. Single-layered cylindrical cable-beam shell and the single-layered cylindrical shell were compared. Then this article calculated long-span ratio, rise-span ratio, cable cross-section, prestress of cables, section areas of steel bars which impact dynamic characteristics of cable-beam shells. The ... |
