Numerical results were performed taking into account non-linear behaviour of rebar and deformation of concrete with further cracking. A comparative analysis between obtained experimental results and calculated ones was performed and their well-enough matches were shown. Prediction of reinforced concrete structures behavior using finite element method was performed. © 2022 The Authors. Published by ELSEVIER B.V.

Introduction According to the best practice, a lot of scientific papers are devoted to model the behaviour of reinforced concrete structures using the finite element method (FEM) (Arduini et al. (1997), Brena et al. (2003), Kachlakev et al. (2001), Murali et al. (2011), Ritchie et al. (1991)). It is well known that experimental methods are the most reliable approaches to study the behaviour of structural elements. However, they are labour-intensive, long-term and require significant material costs. So, numerical simulation of the constructions behaviour can significantly reduce effort in 1st Virtual International Conference “In service Damage of Materials: Diagnostics and Prediction” Prediction of reinforced concrete structures behavior using finite element method O.
