Deck plates are used to maintain traffic in the construction field such as underground road and subway construction etc. To support the traffic load, a lot of steel is needed for this by temporary structure. In order to reduce the amount of steel used and to obtain the optimized structural performance of deck plate, a new type of deck plate is proposed and tested. Finite element analysis of the developed deck plate(HY-DECK) using the ABAQUS was performed to verify the structural safety, and deck plate with of 3000 × 2000 × 6t cross-section was proved the optimal. In addition, end reinforcement from the end of deck to 200mm spans to center of the deck was proved very effective for the stress distribution. Deck plate developed are tested to verify the structural safety using the static structural testing system up to failure. The testing results shows structural safety margin are enough. From comparative verification in this study, it is confirmed that the proposed deck plate having multiple stress distribution mechanism have structural effectiveness and economical for field use.
