Abstract

In reinforced concrete structures, connections between members are often critical for the performance in the ultimate limit state. The most common approach to provide force transfer across the connection is to overlap reinforcement bars to form a lap splice. Here, looped reinforcement laps subjected to tension were studied using a three-dimensional nonlinear finite element approach. For the constitutive model of concrete, a damage- plasticity approach was used. In this model, the input for the tensile response is given in the form of a stress versus crack-opening curve, which, for the case of concrete with fibres, is adjusted to consider the bridging effect of fibres. The influence of lap length and fibres on the mechanical response was investigated. The numerical results show that fibres significantly increase the strength and ductility of lap splices.
