Recent increases in the use of Deep Deck, and the study was carried out much of the Deep Deck in the country. Research is the most studies on the behavior of the composite slab after the concrete is cured. However, the large stress is generated in the work load(150kgf/m2) at the time of pouring concrete. The Deep Deck does not satisfy the provisions of deflection during construction when applied to more than 6.0m span. In this study, installed a strand or reinforcing bar at the bottom of the Deep Deck. The pressing force of tension on the strand and rebar was carried out an experiment to produce an upward deflection of the Deep Deck. The loading experiment was carried out and the pressing force the UTM load.
