Abstract
To realize the industrialized lateral resistant system in steel structure, a low cyclic loading tests is carried out for steel frames with infill prefabricated reinforce-concrete shear walls (solid wall). The crack developed in infill walls and deformation performances of specimen are investigated. And the force transfer mechanism, failure mode, hysteretic behavior, stiffness degradation deformation and ductility and energy dissipation of composite structure are analyzed too. Test results show that the concrete crushing in infill wall is the main failure paten and the failure mode is ductile failure. Within the whole loading period, low cyclic fatigue of shear connectors (U sharp bars) doesn’t occur. The performance of the specimens including post peak strength degradation, ductility behaviors and energy dissipation, are significantly improved. In the whole test the steel and concrete components work integrally. And the specimen has good seismic performances and can be widely used in seismic areas.
