The use of structural fibre as replacement of the traditional reinforcement in precast concrete segmental linings is a widespread practice. As a matter of fact, more than forty examples of application in tunnels and vertical shafts can be cited. The success of using fibres in this structural elements lies in the mechanical improvements (reduction of the crack width, increasing of the toughness, among others) as well as in economic reasons (reduction of the labour force as well as of the production periods, increasing the efficiency, among others) that could be achieved.
In this sense, the main goals of this scientific contribution consist of, on the one hand, presenting and analysing some of the more relevant applications of fibre reinforced precast concrete segmental linings existing up to date and, on the other hand, presenting a numeral strategy to optimize the reinforcement in this sort of elements as well as its application to recent real examples already constructed or under construction in the metropolitan area of Barcelona.
