Abstract EN
Several retrofitting methods for reinforced concrete (RC) beam-column joints in old buildings without seismic details were developed.
Four half-scale RC exterior beam-column joints were fabricated and tested under cyclic loading simulating earthquake excitation.
The control specimen was designed to fail in joint shear.
Two practical retrofitting strategies were applied to the control specimen which consider the architectural characteristic in real buildings, including steel jacketing and haunch retrofit solution.
The structural performance of the test specimens was investigated in terms of various factors including damage and failure, load-drift relationship, ductility, dissipated energy, and strain profiles of longitudinal reinforcement.
Experimental results confirmed that the proposed retrofit methods were shown to enhance the seismic capacity of the joints in terms of the strength, deformation capacity, and energy dissipation capacity while the shear deformation in the panel zone significantly reduced in comparison with the control specimen.
