点式建筑幕墙

点式结构建筑幕墙是我国近几年新的建筑结构形式，该结构形式匠幕墙所承受的各种荷载和作用，以点连接形式传到中间的结构，再由中间结构传到主体结构。介绍了玻璃幕墙，石材幕墙、铝板幕墙和不锈钢幕墙的分类，产柱横梁的正交杆系设计计算方法；根据点式幕墙在我国的应用情况，重点讨论了预应力悬索结构设计计算和不同风荷载下幕墙结构受力的特征。

Point type building currtain wall

The point type structure building curtain wall is a newly developed building structure mode recent years. The structure mode curtain wall is that each load and action borne by this curtain wall are transferred to the middle structure via point connection mode, then to the main structure. This paper introduces arrangement of glass curtain wall, stone curtain wall, aluminium sheet curtain wall and stainless steel curtain wall under categories, and the design calculation way for orthogonal rod system of column and cross beam. In accordance with application of the point type curtain wall in China, this paper focuses discussion on design calculation of prestressed suspended cable structure system and stressing characteristics of curtain wall structure under different wind loads.
