Performance Evaluation of Geopolymer Concrete Beam-Column Joints Using Finite Element Methods
The beam-column joints are the most critical zones in a reinforced concrete building. They are subjected to forces in all directions during earthquakes, and their behaviour has a significant influence on the structure. Thus, highly ductile materials are required for the design of beam-column joints. Geopolymer concrete is environmentally friendly and contributes to sustainable development. As it attains higher compressive and tensile strengths and increases the durability of structures, it can be an effective substitute to OPC. The use of Finite Element Analysis (FEA) to analyse various structural components is gaining widespread importance nowadays. The aim of this paper is to predict the behaviour of GGBS-dolomite geopolymer concrete exterior beam-column joints using ANSYS. Limited experimental studies have been done and further behaviour is studied using Numerical Methods. For this purpose, constitutive relationships are developed from experimental investigations. The displacements, stresses, strains and forces at any point can be determined under different loading conditions. The deflection characteristics, first crack load and ultimate load of beam-column joints are determined. Non-linear finite element analysis is carried out in several load steps taking care of the force and displacement convergence criteria to study the specimen’s behaviour from first crack load to ultimate load.
