摘要:In view of the problems existing in the beam-column joint of prefabricated concrete frame structure, a new hook-type joint is proposed in this paper. The quasi-static tests were repeatedly performed on full-scale models, using combined joints with different concrete strength and steel bar types. The failure pattern, carrying capacity, hysteresis loop and energy dissipation ability of the new hook-type joints were analyzed. The results show that the failure process of hook-type joint has five stages; they are initial crack, thorough crack, beam yield, limit, and failure. The hook-type joints have good working performance, good recovery characteristics and strong strength and stiffness, but the energy dissipation ability is weak.
