Abstract: Increasing popularity of using fibres in concrete has brought questions about their usability in segmental tunnel linings as an alternative to the conventional lining. Prior studies have already revealed that the replacement of conventional steel reinforcement is possible with steel fibres. However, the usability of macro-synthetic fibres (MSFs) as reinforcements in precast tunnel segments is...
Abstract: New procedures for the design of precast segmental lining tunnels have been developed in recent years. The use of glass fiber reinforced polymer (GFRP) bars instead of conventional steel bars is increasing in precast segments. Besides, macro-synthetic fibers are also used as a replacement for traditional steel bars. It is possible to find design guidelines for the design of precast segments...
