摘要
针对天津某大跨椭球形展厅双向钢拱结构和钢-混凝土组合结构2种方案,对比、分析了两种方案的受力性能、刚度特性、经济指标、碳排放等。结果表明,采用钢-混凝土组合结构进行大跨设计时,可保证与双向钢拱结构相当的受力性能,但刚度、经济指标、碳排放量明显优于双向钢拱结构,是此建筑更适合的选择。
Aiming at the two design schemes of the two-way steel arch structure and the steel-concrete composite structure for a large span ellipsoid exhibition in Tianjin, the paper compares and analyzes their mechanical behavior, stiffness characteristic, cost-efficiency and carbon emission, etc.. The results show that the steel-concrete composite structure used for large span building can gain the mechanical behavior similar to the two-way steel arch structure, but its stiffness characteristic, cost-efficiency and carbon emission are better than that of the two-way steel arch structure, so it is more suitable for the building.
