摘要
通过对四边简支拼装棚模现浇混凝土空心楼盖在竖向均布荷载作用下的破坏模型的数值分析,研究了矩形区格空心楼盖的变形模式,得出了此类楼盖的极限承载力,并分析了此类楼盖与普通实心双向板和密肋楼盖的区别。同时与试验数据作对照,研究了此类楼盖数值分析的可行性,并给出了实际的工程建议。
This paper focuses on the numerical analysis of cast-in-situ reinforced concrete hollow rectangular-zone slab, timate load and the co which is simply supported at four edges subjected to vertical uniform load. The ulllapse mechanism are determined through the research, and the difference on this slab, solid slab and ribbed slab are obtained. The feasibility of numerical analysis is studied, and the suggestions of design and construction details are also given.
