Abstract

This paper describes a theoretical study of forty eight (48) Reinforced Concrete RC beam column joints, which generally classified as interior, exterior and corner joints. The most main parameters, which may influence the behavior of beam-column joint, transverse reinforcement, lateral shear reinforcement, longitudinal reinforcement, joint area, column axial load, concrete compressive strength, end boundary conditions …etc. In this research FEA (finite element analysis) using ABAQUS\CAE commercial software will be developed to build a detailed model to predict the nonlinear behavior of beam-column joint under seismic loadings. The ABAQUS\CAE 6.7 solution is a practical way to implement the nonlinear dynamic earthquake analysis for the finite element model. Our study is focusing with joints where statically lateral load was applied and gradually increased maintaining constant axial load at the top of the column equal to 0.15 (AcFc). Several linear variable horizontal displacement transducers were mounted , the net story drift, bond stress, axial shear stresses and strains as well as energy absorption for using different grades of concrete C250, C400, C600 and C1200 are evaluated and discussed to illustrate the behaviour of the studied joints under the case study of loadings.
