摘　　要：结合工程实例,以某大型超市楼盖为研究对象,利用有限元软件YJK进行结构分析与设计,通过比较薄壁箱体现浇混凝土空心楼盖和现浇混凝土实心楼板两种楼盖体系在荷载、跨度等相同参数条件下的经济指标,提出薄壁箱体现浇混凝土空心楼盖体系的适用范围。通过对两种楼盖结构体系在相同条件下的混凝土和钢筋用量的分析比较中可以得出:只要结构的跨度大于9m,无论所受活荷载大小,薄壁箱体现浇混凝土空心楼盖结构体系均会具有更好的经济性能,且其经济性会随着结构跨度和荷载的增加而更加明显。Combining with the project example,a large supermarket floor is taken as the object of research, and the finite element software YJK is used to simulate and analyze. The applicable scope of cast-in-situ concrete hollow floor with thin-wall core box is proposed by comparing economic indicators of the cast-in-situ concrete hollow floor with thin- wall core box and cast-in-situ concrete solid slab under the same parameters such as load and span. Based on comparative analysis of the amount of concrete and steel of the two floor structure system under the same conditions, it can be concluded that when the structural span is more than 9m, no matter what size of the live load, the cast- in-situ concrete hollow floor with thin-wall core box will have better economic performance, and this kind of economic growth will be more apparent with the increase of structural span and load.
