In this study, a new Lattice integrated Rib-Type Deck Plate system is proposed to enhance the flexural stiffness and strength. This system integrated a rib-type corrugated deck with a steel wire lattice designed for short spans, which is placed on top of the corrugated deck. To validate the flexural performance of the proposed system, experimental programs were conducted for both the construction stage and the composite stage. Construction stage test results showed that all specimens exhibited deflections less than 13mm under the construction load, satisfying the maximum deflection limit of 19mm. Composite stage test results indicated that increasing the amount of tension and compression reinforcement led to improvements in initial stiffness, yield strength, and maximum strength. Furthermore, specimens with reinforcement in the compression zone demonstrated superior ductility. The flexural strength of all tested specimens was confirmed to be safely evaluated by the flexural strength equation specified in the Korea Design Standard.
