Finite element model of reinforced concrete interior beamcolumn joints subjected to cyclic loading

Abstract

This paper presents the finite elements of beam-column joints subjected to cyclic loads. This study aims to numerically obtain the beam-column joints' capacity without shear reinforcement in the joints. The variable used in the specimen is the beam's longitudinal reinforcement ratio. While the analytical study was carried out using ATENA 2D software, a computer program based on the non-linear finite element method. In this analytical study, the beam-column joints are loaded cyclically to obtain the envelope curve of the hysterical response. The results of this numerical analysis are then compared with the test results. The comparison results show that the model used in ATENA 2D can approach the test results well. In addition, the crack pattern obtained from the analysis shows a pattern close to the test results.
