摘要
The possibility of substituting the traditional steel reinforcement with Glass Fiber Reinforced Polymer (GFRP) bars in precast segmental lining tunnels is investigated herein. The use of this kind of reinforcement in tunnel segments allows several advantages mainly related to durability aspects or when provisional lining is forecast. Furthermore, GFRP reinforcement can be used when dielectric joints are necessary. In the presented research, full-scale bending tests have been performed on precast segments in order to compare the structural performance of GFRP reinforced concrete with respect to traditional steel reinforced concrete. Furthermore, peculiar aspects of the design procedure for the proposed solution are remarked and discussed. (C) 2016 Elsevier Ltd. All rights reserved.
