| Abstract: | This paper focuses on the numerical analysis of cast-in-situ reinforced concrete hollow rectangular-zone slab,which is simply supported at four edges subjected to vertical uniform load.The ultimate load and the collapse 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. |
