Abstract:Combined with the engineering practice of substation, and considering the convenience of construction, a new type of new prefabricated partial steel reinforced concrete(SRC) frame joints was designed. Behaviors of the full-scale model of the new prefabricated joints under low cyclic loading were studied including failure modes, hysteretic characteristics, skeleton curves, ductility and energy dissipation capacity, and the results were compared with those of the cast-in-place joints and general prefabricated joint. The results show that the new prefabricated joints have good ductility, energy dissipation capacity and bearing capacity. The new prefabricated joints are feasible for assembly structures.
Keywords:prefabricated frame; partial steel reinforced concrete(SRC); quasi-static test; seismic performance; joint core
