Recently, for the decreasing of work term and the convenience of construction work, the steel wire-integrated deck plate has been widely used in the construction sites. Most of all, owing to its good stiffness and economic consideration, the steel-wire-integrated deck plate system has become very popular in recent years. Upper bar, lower bar and lattice bar of the steel-wire-integarated deck plate work as upper chord, lower chord and diagonal chord of truss respectively. Lattice bar is easy to buckle and effective buckling length is increased when the thickness of lattice bar is small. Therefore, tests have been conducted on 15 specimens with several experiment variables to evaluate the structural safety of the proposed deck plate system during the construction step. The test results show that in case of the steel wire-integrated deck plate with 6 mm lattice bar, it effectively deals with the shear force on the end, therefore considerably strong.
