FORMATIONS AND SPATIAL WORKING MECHANISM OF SPATIAL CABLE-STRUT-SUPPORTED RIGID STRUCTURE

摘要

To fully understand the formations and working mechanism of cable-strut-supported rigid structure and extend its application, the representative compositions of cable-strut-supported shell structure of Anhui University gymnasium, cable-strut-supported radiating planar truss structure of Beijing University gymnasium and cable-strut-supported parallel spatial truss structure of Quanzhou gymnasium are introduced in this paper. Based on the analyses of static properties of the gymnasiums, spatial working mechanism of cable-strut-supported rigid structure and the properties of this type of structural system are analyzed. Analysis results show that based on the working mechanism of cable-strutsupported rigid structure, different kinds of layout of cable-strut system can be adopted, whole cablestrut-supported shell structure is much better than the partial one. Combining rigid structure and cablestrut system is a good way to minimize thrust force of support and to maintain stiffness of the whole structure.
