프리캠버 형성을 위한 7.5m 장스팬 Deep Deck 처짐실험

Slim floor systems with Deep Deck are often used to reduction of story height. The span is increased in order to maximize the profitability efficiency. However, when used the Deep Deck to 6m or more spans, the deflection caused by the construction load produces the usability problems. In order to solve this problem, it is necessary to install surport. This is because increasing the construction period and cost, reduces economic efficiency.In this study, installation of strands to 7.5m Deep Deck. When the tension on the strands, upward deflection is to occur and to minimize the downward deflection,. Thus, the experiment was carried out by applying the strand on Deep Deck.
