Abstract:Interactive behavior between steel and concrete of a composite grid in the multifunctional training gymnasium of Zhenjiang Sports and Exhibition Center was investigated, and parameter analysis of the influence of concrete slab thickness was conducted to determine the economical range of slab thickness. Relationship between slab thickness and its natural frequency and deflection was researched. The results show that the natural frequency increases and deflection decreases obviously with the combination of concrete slab, but the natural frequency and deflection dont change linearly with its thickness. When the thickness reaches a limit, as weight increases, its natural frequency will decrease and the deflection will increase. Design of connection joints between steel grid and concrete slab was also presented, which could be reference for similar structures.
Keywords:composite grid structure; structure analysis; economical slab thickness; joint design; finite element method
