摘要
空间管桁架作为一种新型的空间结构体系,具有刚度大、用钢量小、施工方便、经济环保性能优等特点,广泛应用于大型输变电站、体育馆、车站等大跨空间结构中。通过对管桁架结构布置、稳定性和抗震性能的分析,讨论结构外观体型布置对大跨度结构内力及变形的影响,为同类结构设计提供参考和借鉴。
As a new spatial structure system,the structure of the spatial tube truss has the features of great rigidity,small in amount of steel,convenient for constructing,economical and environmental in performance and therefore it is widely used in substations,stadiums and railway stations. Based on an analysis of the structural arrangement,stability and seismic performance the tube truss,this paper discusses the effects of the outer structural arrangement on the internal forces and deformations of the large-span structure in a bid to provide useful reference for the design of similar structures.
