Abstract：
The traditional architectural structures a lot of concrete is the scene of casting, not only the pollution of the environment, making noise, but also increased the labor intensity, and at the same time, to guarantee the quality of the project. This article through to the structural type for composite beams with dense rib of the floor of the engineering example, the author introduces a method first prestressed concrete composite type flexural members of the calculation principle and structure of the building in the application. From the implementation of the project ultimately situation, this kind of composite beams with application of multi-ribbed slab structure system has low cost, high beam, span, construction speed is quick, seismic performance is good, and so on various advantage.
