Seismic behavior evaluation of exterior beam-column joints with headed or hooked bars using nonlinear finite element analysis
S. Rajagopal, S. Prabavathy and Thomas H.-K. Kang

 
Abstract
    This paper studies the response of seismic behavior of reinforced concrete exterior beam-column joints under reversal loading with different anchorages and joint core details. The joint core was detailed without much confinement (group-I) and/or with proposed X-cross bars in the core (group-II). The beam longitudinal reinforcement\'s anchorages were designed as per ACI 352 (headed bars), ACI 318 (conventional 90o bent hooks) and IS 456 (90o bent hooks with extended tails). The nonlinear finite element analysis response of the beam-column joints was studied, along with initial and progressive cracks up to failure. The experimental and
