The Research Of Key Problems Of Big Spatial Floor

Recently,with the development of the economic and the improvement of the living level,more and more factory,gymnasium,showplace have appeared . This means that the spatial structure is more and more used in our life,it is gaining a rapid development .At the same time,Composite structure has longer foreground which is used for overcoming the disadvantage of steel & concrete and utilizing their respective strongpoint . The composite of steel beam and reinforced concrete deck slab has been used and researched . But the research for composite structure of steel lattice grid and concrete slab is not enough .On the other hand,connector is one of key factors for ensuring that steel lattice grid and concrete slab can work together . Stud is used more abroad than other connectors . It is researched by entity finite element .Combine with the idiographic project Nan-tong Olympic Stadium,the writer will do some research and analysis in the key problems,such as:(1)The influence of considering slab working for structure rigidity;(2)The influence of eccentricity of slab;(3)Structure optimization on idiographic project Nan-tong Olympic Stadium;(4)The research of reasonable distributing of stud in concrete .In the end,feasibility advice for structural design is taken by analysis and research for the idiographic project Nan-tong Olympic Stadium .
