A Study on the Structural Characteristic of Strengthened Bridge Deck Specimens Using External Bonded Plate

Plate로 전면보강된 교량 상판의 거동특성에 관한 연구

Punching shear in concrete slabs is a serious problem in certain structural systems, such as flat slab. In this study, mechanical improvement between specimens which are unstrengthened and strengthened with steel plate and fiber panel is experimentally investigated. The strengthened bridge deck specimens had increment of strength and broke down with punching shear failure. Strengthening ratio should be considered to restraint punching failure.
