Review on Mechanical Performance of Concrete Laminated Slabs

Prefabricated structures meet the requirements of industrialized construction production and are increasingly used in the field of construction. Among them, the laminated slab is widely used in practical projects as a new type of component. In prefabricated buildings, the laminated slab can not only significantly increase the prefabrication rate, but also has the advantages of good integrity, saving templates, flat bottom surface, and efficient construction. Applied to a variety of prefabricated structural systems. This article summarizes the mechanical performance of concrete laminated slabs by using the literature survey method, and elaborates in detail on the indirect lap joint performance of concrete laminated slabs and additional reinforcement at the wall or beam support, the shear performance of concrete laminated slabs, and the overall performance of laminated slabs And the research status of the seismic performance of different joints of the composite structure, and the development trend of the concrete composite structure prospects.
