Abstract: To realize the industrialized lateral resistant system in steel structure,the low cyclic loading test was carried out for steel frames with infill prefabricated reinforce-concrete shear walls( SFPCW).  The crack development in infill walls and deformation performance of SFPCW were investigated,and the force transfer mechanism, failure mode, hysteretic behavior, stiffness degradation, deformation and ductility, and energy dissipation of composite structure were analyzed too. Test results show that the concrete crushing in infill wall was the main failure pattem and the failure mode was ductile failure. Within the whole loading period, low cyclic fatigue of shear connectors(U shapebars)  didn't occur, and the performance of the specimens, including post-peak strength degradation, ductility behavior, deformation capacity, and energy dissipation, were significantly improved. During the whole test, the steel and concrete components work integrally. And the SFPCW have good seisnuc performances and could be widely used in seisnuc areas.
