Profiled steel plate-concrete composite floor slab is a new type of composite structure, which is increasingly used in high-rise buildings with large span structures because it can make full use of the excellent characteristics of steel and concrete, and has broad development prospects. Due to the excellent properties of profiled steel plate-concrete composite floor slabs, it has attracted extensive attention in recent years, and experts and scholars in China have also carried out a lot of research on its stress and deformation.

In this paper, combined with the tower engineering, the profiled steel plate used in the construction is designed, especially the flexural bearing capacity and deflection of the section in the construction stage, and the flexural bearing capacity, oblique section bearing capacity, deflection and natural frequency of the profiled steel plate-concrete composite floor slab are also checked to ensure that the profiled steel plate used in the project meets the application requirements.

Compared with ordinary reinforced concrete floor slabs, profiled steel plate-concrete composite floor slabs have the following advantages: short construction period; Small dead weight, saving materials; increase the seismic performance of the structure; Efficient use of space for the floor structure. Compared with the traditional wood formwork, the probability of fire is reduced during the construction of the profiled steel plate-concrete composite floor slab.
