Correlation of the results of the standard beam and EFNARC panel test
Abstract: Fibre Reinforced Concrete (FRC) is widely accepted in the tunnelling industry for use such as shotcrete, cast-in-situ linings or Tunnel Boring Machine (TBM) concrete linings. To calculate an FRC structure the generally accepted method is to measure the parameters of the FRC using the standard 3 point beam test, measuring the load, deflection and/or crack mouth opening displacement (CMOD)....

Design Aspects of Fibre Reinforced Shotcrete Linings based on Experimental Test Results
Abstract: The design of fbre reinforced shotcrete (FRS) linings for tunnels or mines is commonly based on the well-known and widely recognised Q-System or Barton charts. This performance based design approach accesses the results of experimental tests, carried out on panel specimens according to existing standards or guidelines. This is different to the general methodology to access and determine the...

Full-round numerical analysis of traditional steel bar and macro synthetic fibre reinforced concrete segments for the...
Abstract: The fibre reinforced concrete (FRC) in question is a short fibre composite, where the matrix is a quasi-brittle material: concrete, and the fibres are made of different materials (e.g. steel, polypropylene, etc.) with different shapes (e.g. round, oval, etc.), random but uniformly distributed, relatively short fibres. The synthetic fibers started to spread in the industry in the last decades,...
