Retrofitting Seismically Designed Exterior Beam-Column Joints under Lateral Monotonic Loading: A Numerical Analysis Based on Experimental Testing

This research paper presents an experimental and numerical study on the behavior of reinforced concrete (RC) in exterior beamcolumn joints designed for seismic conditions. Three laboratory specimens were prepared and tested to evaluate their load-bearing capacity and study the joint behavior under a constant axial load and a gradually increasing peak monotonic load until failure. The experimental results demonstrated convergence among the …
