Finite element modelling of RC beam-to-column joint

Résumé

In this paper, a Finite Element Model (FEM) of Reinforced Concrete (RC) beam-to-column joint is investigated. The validation of the FE model is base to the experimental results, which are part of an experimental campaign lead up at the University of Salerno. The FEM study is developed and analyzed using Abaqus software. The analytical investigation is carried out through an extended comparative parametric study and is focused on the quantitative influence of certain simplified modelling assumptions and several critical modelling parameters on the response of the system. Great attention is given to define the material response, especially the reinforced concrete. The constitutive laws of concrete, both in compression and in tension, are modelled based on the results of laboratory tests and well-known literature references. The specimen is calibrated according to a monotonic loading, as a preliminary stage before running cyclic analyses. The results of the calibrated numerical model are reported in terms of load-displacement curve and plasticity.
