The possibility of substituting the traditional steel reinforcement with fiberglass bars in precast segmental lining tunnels is investigated herein. The use of fiberglass reinforcement in tunnel segments allows several advantages, mainly related to durability aspects or when provisional lining is forecast. Furthermore, this 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 fiberglass reinforced concrete with respect to traditional steel reinforced concrete. Furthermore, peculiar aspects of the design procedure for the proposed solution are remarked and discussed.

Abstract
The possibility of substituting the traditional steel reinforcement with fiberglass bars in precast segmental lining tunnels is investigated herein. The use of fiberglass reinforcement in tunnel segments allows several advantages, mainly related to durability aspects or when provisional lining is forecast. Furthermore, this 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 fiberglass reinforced concrete with respect to traditional steel reinforced concrete. Furthermore, peculiar aspects of the design procedure for the proposed solution are remarked and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
