摘要: 点支式玻璃幕墙柔性支承体系是一种新型的支承体系, 因其具有通透性好、轻盈美观和施工灵活等特点得到广泛应用。由于需要考虑预应力和几何非线性大变形的影响, 这给柔性支承体系的设计增加了难度。结合北京土城电话局单层索网幕墙和鱼腹式自平衡采光顶的设计, 对该类复杂柔性支承体系的设计计算过程进行介绍, 并对诸如幕墙结构的承载性能、荷载计算工况和过载保护装置设计等问题进行了详细说明。

Abstract: Flexible support system for point-supporting glass curtain wall is a new kind of system. It has been widely used for its fine transparence, light weight and flexible construction etc. Because of the influence of prestress and large deformation, there are many difficulties in the design of cable nets. Combined with the design of single-layer cable net and fish-bellied self-balance cable truss of Tucheng Telephone Exchange of Beijing, this paper gives the introduction to the design of flexible support system. This paper also discusses some important gists such as the carrying capacity of the flexible support system, the load cases for calculation and the protection equipment for over loading.
