A Study on Seismic Analysis of Beam –Column Joint at Seismic Zone III

Beam-column joints are critical components in reinforced concrete structures, particularly vulnerable to seismic forces. This study investigates the seismic behavior of beam-column joints through comprehensive analysis and numerical simulations. The research focuses on evaluating the performance of various types of joints under seismic loading conditions. Nonlinear static and dynamic analyses are employed to assess factors influencing joint response, including detailing, reinforcement configurations, and material properties. Key parameters such as shear stress distribution, concrete confinement effects, and bond-slip behavior are examined to understand the seismic vulnerability of these joints. Performance metrics such as ductility, energy dissipation, and failure modes are analyzed to enhance structural design practices. The findings contribute insights into improving the seismic resilience of beam-column joints, providing practical recommendations for optimizing their design and detailing to mitigate potential vulnerabilities and ensure structural safety.
