Deep-Deck usually used in long span structure for its larger section properties. but Deep-Deck has difficulties when the span is over 9m because of deflection. Deflection makes workers anxiety and Structural problems. So, Preload is used to the Deep Deck To control the the deflection of the deep deck which has 9m over. In this study, The Preloaded deep deck which has 9m was evaluated by Experments. Result of experiments, preloade and camber have proportional relation
