Abstract
Fibre reinforced concrete (FRC) is increasingly used in tunnel segmental linings constructed with tunnel boring machines. Several codes include the FRC as a structural material and specific guidelines cover the design of FRC precast segmental linings. All of these consider the traditional limit state format, applying partial safety factors to the loads (¿L) and material strengths (¿M). Often, the ¿M applied to the residual tensile strength of FRC is assumed the same as for concrete in compres...
