Experimental Study on the Long Span Precast Decks

프리캐스트 장지간 바닥판의 정적 및 피로실험

Transverse prestressing of bridge decks is an attractive concept with substantial benefits in both economy and crack control in slabs. To evaluate the necessary information for the prestressed long span bridge slab design, a series of static and fatigue tests were peformed. It is shown that the minimum thickness recommendation in Korean Highway Bridge Design Code is too conservative.
