Title: Structural response of beam-column joint made of fiber reinforced concrete (FRC) using ANSYS FEA simulation

Description:

Beam-column joints are crucial in reinforced concrete and steel structures, which transfer load from beams to columns and vice versa. They are essential to withstand various types of loads, such as lateral, gravity, and seismic loads. The material of the beam-column joint determines the joint's ability to withstand and transfer loads between beams and columns. The stronger material would enhance its strength and overall load-bearing capacity and vice versa. Current research aims to evaluate the structural response of beam-column joints made of Fiber Reinforced Concrete (FRC's) using ANSYS FEA simulation package. The effect of fiber concentration, i.e., 0.3%, 0.6%, and 0.9%, on the strength of the beam-column joint is evaluated based on structural evaluation parameters. The other objective is to evaluate the effect of graphene fiber (the aspect ratio is 1:1, although up to 1.5 is typically acceptable) on improving the strength of the beam-column joint. Comparative studies are conducted, and materials are evaluated based on stiffness, ductility and energy dissipation. The graphene-reinforced concrete demonstrates less stiffness degradation with increased strain. This indicates that the incorporation of graphene improves the stiffness retention capacity of the concrete. The hysteresis loop of graphene-reinforced concrete is broader, signifying enhanced ductility. This indicates that the material can sustain greater deformations without failure, essential for seismic performance. The 0% FRC has minimal ductility, characterized by a notable reduction in stress upon first loading. The 0.3% and 0.6% FRC show improved ductility, with higher stress levels maintained over larger strains. The 0.9% FRC demonstrates the highest ductility, maintaining higher stress over the full strain range, indicating it can undergo larger deformations without failure. The stiffness degradation is less pronounced in higher FRC concentrations.
