철선의 방향에 따른 중공 데크플레이트의 부착특성

초록

The void deck plate has a structure in which a void body is inserted into a deck plate, and the inner cover thickness is different because the shape of the void body buried along the direction of the steel wire located in the two-directional slab is different. Previous studies have confirmed that the bond stress decreases when the inner cover thickness is less than 2.5d . Therefore direct pull-out test was carried out to determine the bond characteristics of the void deck plate by setting the direction of the steel wire as a variable. As a result, it was confirmed that the maximum bond stress was affected by the inner cover thickness and the embedded length when comparing with the direction of the steel wire.
