摘要
索托结构是一种新型大跨结构形式,利用拉索与主体结构之间设置的传力机构,使得斜拉索中的水平力不再作用于主体结构.因此其受力较斜拉结构更加合理而具有广泛的应用前途.它是一种既不同于斜拉结构,也不同于悬索结构的一种新型的拉索结构形式.它已经应用于一些大跨度房屋建筑工程中.本文介绍了在北京市芦城体校曲棍球馆工程中采用这种新型结构形式的具体做法、计算方法和工程体会.
The cable-held structure is a new form of long-span structures.By the use of the contact nodes between cable and main truss frame,the horizontal component of cable force is no longer applied on the main truss frame.Therefore the internal force of cable-held structure is more reasonable than that of the cable-stayed ones.The cable-held structure has broad applications.It is different from cable-stayed structure and the suspension structure.It has been applied to a number of long-span engineering.This article introduces the construction,calculation method,and some experience on Beijing Lucheng physical training school project.
