Regularisation methods for modelling flexural dominant lightly reinforced concrete walls

•Develop reliable regularisation approaches that can be implemented into fibre models to simulate the cracking and reinforcement fracture response for lightly reinforced concrete walls.•Methods for regularisation of both the reinforcement and concrete material properties using a fracture energy method were proposed to minimise the effect of element size on the strain localisation during nonlinear analysis of lightly reinforced concrete walls.•The local strain validation highlighted the post-processing of model outputs required to achieve objective simulation results.
