Abstract

The possibility of substituting traditional steel reinforcement with glass fiber-reinforced polymer (GFRP) bars in precast concrete tunnel segmental linings is investigated. The use of GFRP reinforcement in concrete tunnel segments results in several advantages mainly related to durability enhancement or when a temporary lining is required. Full-scale bending tests were performed on concrete segments reinforced with GFRP and steel bars in order to compare their structural performance. The results show the effectiveness of the proposed GFRP solution for this type of application. Additionally, a case study is developed presenting provisions for safety checks on GFRPreinforced tunnel segments.
