Abstract |
In recent, the investigations related to the FRP(Fiber Reinforced Polymers) have been increased due to their superior material and mechanical properties such as environmental resistance, high specific strength and stiffness. Considering these advantages, the FRP tube may be proper for strut on the PSC box girder bridge that can maximize the efficiency of cross section and are effective on economics and aesthetics of bridges. In this research, the specimen tests of the FRP tube and compression tests of the concrete member enclosed with the FRP were performed in order to evaluate the suitability of the FRP tubes, which are applied to the PSC box girder bridge with strut. The specific strength of concrete and the energy absorbing capacity as well as ductility were increased according to the experimental results, and it was found that FRP tubes have sufficient safety as strut member
