In order to prevent the slippage between the floor deck and the reinforced concrete, studs are needed in both ends of floor deck, the studs should be placed on the end base of deck sheet and go through the concave part of the board to be eventually welded together with the edge of the steel girder.
Reinforcing steel bars are needed for the composit slabs under any of the following circumstances
1.To provide additional tensile steel bard for the reserve of loading capacity to the composite slabs.
2.Continuous steel bars provided for the continuous composite
3.Steel bars laid in the area of centralized load/surrounding holes
4.Tensile steel bars provided for the improvement of fire-resistant.
