摘要
对大跨度结构(l>60m)来说,材料用量多,不仅是一种浪费,对结构的竖向抗震也极为不利.优秀的大跨度结构必须采用空间结构.梁式结构体系(桁架是格构式梁)不宜在大跨度结构中采用.根据我国的技术经济政策,即技术先进、安全适用、经济合理、确保质量,本文提出衡量大跨度空间结构优劣的五个指标,可供建筑和结构设计人员参考.
For longspan structures(l>60m),consuming too many materials is not only a kind of waste, but also harmful to the structural vertical earthquake resistance. Spatial structures must be adopted in the design of excellent longspan structures. Beamtype structures should not be used in longspan structures because of their inferior mechanical behavior. According to the policies of technology and economy in China, that is to be advanced in technology,safe,applicable,rational,economical and with good quality,this paper presents five indexes for the evaluation of longspan spatial structures, which can offer a good reference to both architects and structural engineers.
