초록

Deep Deck plate is suitable to long span structures because it has larger flexural rigidity than other shape deck plate. but Deflection is critically proportional to span length than other factors. and large deflection makes works anxiety and possibility of structural problems high after casting concrete. to overcome these problems, Preload is introduced to control the deflection of deep deck plate that ha s long span. So in this study, residual strength of preloaded deep deck plate is evaluated by FEM analysis method. for this study 4 analysis models is used and have each preload. Target preload for analysis models is when deck plate cambered to 30mm. 0.0, 0.8, 1.0, 1.2, times of target preload are applied to each analysis models. In result of analysis, Preload influence residual strength of deck plate. And much preload degrade strength of deck plate.
