- Abstract:
- Based on tests of three specimens under low cycle reversed loading，the failure pattern，hysteretic loops，stiffness degradation and energy dissipation capacity of connections between concretefilled steel tubular columns and prestressed concrete beams were studied. The results show that prestress almost has no influence on the failure pattern of specimen, and all specimens are subjected to bending failure at beam end. When the lower part of beam is in tension, prestress makes stiffness degradation accelerate, and energy dissipation capacity is reduced. When the upper part of beam is in tension, the ultimate bearing capacity, stiffness degradation, ductility and energy dissipation capacity of prestressed specimens is better than that of nonprestressed specimens.
