Abstract:The use of fibres as the main reinforcement for concrete pipes is recognized as an attractive alternative to steel bars, especially for smaller diameters. Nevertheless, the use of
fibre reinforcement has not been consolidated yet. The lack of more reliable procedures for systematic quality control of the steel-fibre-reinforced concrete pipes is one of the reasons for
that condition. In addition, there are no reliable technical data to support durability evaluation. A numerical simulation of the pipe crushing test can be used, with the goal of reducing this
lack of knowledge. This paper presents a new solution based on a numerical simulation of steel-fibre-reinforced concrete pipes using constitutive equations derived from Barcelona
tests. An experimental campaign was carried out to confirm the suitability of both the model and the constitutive equation to simulate the pipe response subjected to crushing test. This is
an important tool to support evaluations of the ultimate limit state and serviceability limit state of fibre-reinforced concrete (FRC) precast elements. This is of particular relevance when the new concepts of the fib Model Code for Concrete Structures 2010 are taken into account.
