Despite the deck plate used as composite slab or slab form is a light gage steel, it has a good section performance and it is not necessary to provide supports on slab form in mild and small span to ensure a field working space, safety, and efficient workability. To solve this problem structurally, the cross section maybe made to the shape of the closed cross section by installing the cap plate on top of the deck plate to overcome the instability of an open cross section and to suppress the central variants by increasing the stiffness of the section. In this study, the structural capacity of the self drilling screw connection between the deep deck and the reinforced cap plate was evaluated by experimental variables such as screw arrangement method, screw numbers, screws pitch, and screws head plate thickness.

Recently, the economy in using steel deck is achieved due to constructing ability and speeding. Normally, spans less than 5m can be without propping, in excess of 5m will propping. An innovative deep deck system with cap plate is proposed intend to eliminate propping, and its method are evaluated the stiffness and strength by flexural test as construction loading. The performances of the proposed deck system are examined so as to verify its actual applicability. Consequently, this innovative capped deck is seen to offer improved a flexural strength and a compressive buckling stability in floor construction.

Power actuated fasteners in sort of mechanical methods have appeared to be an alternative to metallurgical methods in the connection of a structural steel member and a thin steel plate. Power actuated fasteners can be driven by power actuated tools or by pneumatically driven tools. Mechanical methods have appeared to be an alterative to metallurgical methods in the connection of a shear connector on composite beam. Also, This method can improve the problems of the welding(the labor-intensive and security of weld quality). We will consider a shear connectors using mechanical connection method instantaneously installed in a steel beam using the explosive power of gunpower. The shear tests on shear connectors, which is X-HVB80 shear connector(Hilti corporation), WT(Wide Type) shear connector, PBT(Perfor-Bond Type) shear connector, and IT(Inclined Type) shear connector, are carried to evaluate structural behavior of shear connectors. Also, this research supplies the fundamental data to the design criterion of this mechanical method by clarifying the influence of the mechanical method on the shear connectors' property.
