摘　　要：由于楼盖在建筑物中所占面积大,重量以及土建造价在总建筑物中所占的比例都较高,因此降低楼盖的造价和自重,减少楼盖结构高度对整个建筑物来说是至关重要的。采用不同结构形式的楼盖,不仅直接影响到结构的受力与变形,而且还对工程造价、施工、工期以及建筑隔声、隔热、室内采光和建筑效果等都会产生影响。文章计算了四种楼盖体系在不同跨度、不同荷载作用下的材料用量及造价,并对这四种楼盖结构体系进行综合经济分析,供设计人员在前期设计时参考。Since the floor constitutes a main part of the area in the building and its weight and the construction cost are also in a large proportion to the total building, it is very important for the whole building to reduce the construction cost, weight and height of floor structure. Adopting different types o ffloor structure will not only have a direct effect on the stress and deformation of the structure, but also affect the cost, construction process, time limit for the project, sound or heat insulation, indoor lighting and architectural effect. This paper has calculated the material consumption under different loads and different spans and construction cost of four types of floor systems, and made a comprehensive economic analysis o fthem, which provides a reference for designers in the preliminary designing stage.
