- Abstract
Prefabricated concrete structure has the advantages of being constructed fast, high quality, energy conservation, good seismic performance and environmental protection, etc. It is the developing direction of the future buildings. It's one of the important research content of prefabricated concrete structure to study the prefabricated components, o f which precast floor is the most important one. At present, steel truss composite slab is adopted in most of the structures. Its integrity performance is good, but it has the shortcomings like the dosage of steel, the slab being very thick and so on. Therefore, a new type of laminated slab with shear keys is put forward, of which the shear keys is used to replace the steel truss to make sure the integrity of laminated slab. It can reduce the steel dosage and make the slab thin, which will save the cost of the whole building. In order to make it clear how the shear keys work in the laminated slab, the shear distribution of the shear keys along the X direction and along the Y direction of laminated slab is analyzed. The results show that: along the X direction and along the Y direction, the shear at the outermost lines changes with no obvious regularity compared with the inner three ones and its value is negative or positive; from the second to the fourth lines, the shear changes in some regularity; the shear keys can connect the precast layer and cast-in-place layer of the laminated slab well.
