FEM Performance of Beam-Column Joint under Cyclic Loading with Column Inclination at Joint Portion

Abstract

Outside non-ductile reinforced concrete (RC) beam-column connections are the primary subject of this article's analysis of their cyclic behaviour. This study utilizes experimental data and complex finite element simulations to probe the effect of angle inclination on the link. During the course of the experiment, both standard RC beam-column junction specimens and specimens with an angled column at the joint were tested. The samples were detailed for seismic activity. Physical test findings were contrasted with those obtained from computer-generated FEM simulations of similar specimens. In this research, we use the ANSYS software to perform in-depth 3D non-linear finite element (FE) simulations of beam-column junctions made of reinforced concrete (RC) at a range of inclinations. Beam-column specimens are subjected to cyclic loading in reverse with carefully calibrated amplitudes so that we can study how these parameters respond to repeated loading cycles. Finite element analysis results for energy dissipation and stiffness versus displacement are quite similar to experimental data. With its excellent ductile behaviour, ferrocement can be used as a hybrid reinforcing solution to improve the seismic performance of RC beam-column junctions. Analytical analyses supported the experimental research using finite element models developed with ANSYS software. The results show that the hysteresis simulation works well for both un-strengthened and ferrocement-strengthened specimens, proving its worth in practice.
