Improvement of Seismic Performance of Beam-Column Joint Using Non-conventional Reinforcement Detailing
The beam-column joint is the crucial zone in a reinforced moment-resisting frame. In the present study, the performance of the beam-column joint region has been strengthened by incorporating novel reinforcement detailing. Tests are conducted for different specimens with extra cross-bars provided in addition to the conventional reinforcement detailing present in the beam-column (BC) specimens under a cyclic actuator of the capacity of 100 kN. The parameters involved in the study are applied load, deflection, degradation in the stiffness and drift angle, and energy dissipation in the beam-column joints. The specimens were also modeled and numerically analyzed using ANSYS-v14 software. Static analysis procedure has been used to determine the key parameters like displacement, stress, strain, and forces in structural components due to the applied loads. Control specimens were prepared using conventional reinforcement detailing and with normal concrete of M25 grade of concrete as it is commonly used for low-rise building constructions. Four different specimens were prepared with extra cross reinforcement in the joint region in addition to conventional and code-based reinforcement detailing present in the specimen. Results indicate substantial improvement in the strength and deformation capacity of the specimens with the inclusion of extra cross-reinforcement in the joint region.
