地下室顶板结构多种方案的经济性分析

The Economic Analysis of Multi-schemes Toward the Structure of Basement Roof

对地下室顶板井字梁布置方案、十字梁布置方案、无梁楼盖方案、加腋梁板方案等四种布置方案进行经济性比较分析,综合考虑造价、施工因素、结构性能等因素,认为地下室顶板采用无梁楼盖方案和加腋梁板方案相比较于传统的主次梁结构布置方案具有更加广泛的应用前景。

In this paper,four schemes toward the structure of base roof are put forward such as the cross beam,rood beam,girderless floor system,and haunched beam.After the comparison between the influence of economy,construction,and structure performance etc,it draws a conclusion that the girderless floor system and haunched beam are better than the traditional beam-slab structure when applied in the basement roof.
