Abstract:
Fiber reinforced plastic (FRP) is a new structural material in the civil engineering field. Paper describes the mechanical properties of prestressed concrete (PC) beams reinforced with FRP as external cables instead of ordinary steel tendons. PC beams using FRP show almost the same mechanical behavior (such as load-displacement characteristics and cable condition) as that of ordinary steel tendons. An analysis procedure is shown to provide a fairly accurate strength prediction of such PC beams at the ultimate state. The external cable system using FRP can be applied to actual PC structures. 222-493
