摘　　要：针对某大跨度混凝土楼盖的设计问题,提出了两种楼盖结构布置方案,方案一为钢筋混凝土楼盖结构;方案二为预应力混凝土楼盖结构。经计算分析,并对两种设计方案抗震性能、梁裂缝和挠度、柱配筋及结构材料用量与造价进行了对比。对比结果表明:预应力混凝土楼盖结构的受力更加合理,且建造成本相对较低。According to the structural design of large-span concrete floor,the author puts forward two feasible plans for the floor structure scheme.The first scheme is the ordinary reinforced concrete floor structure;the second scheme is the prestressed concrete floor structure.According to the results of structural analysis,the seismic performance,beam crack and deflection,column reinforcement and structural material dosage and cost of the two design schemes were compared.The comparison results show that the force of the prestressed concrete floor structure is more reasonable for the design of the large span concrete floor.And the construction cost is relatively low.
