During the past twenty years, the studies in jointed precast connections were much less than those in emulation monolithic one. The pseudodynamic tests of two jointed precast concrete frame structures including one frame with one floor and double spans, and another frame with one floor, single span, and three bays have been carried out to investigate the seismic behavior of jointed precast concrete frame structures on failure mechanism, strength, ductility, hysteretic characteristics and energy dissipation. The precast beams and columns were assembled together with a prestressed bolt and a rubber cushion was inserted between beam and column in the connections. The test results showed that this kind of structures can provide satisfactory seismic performance. When drift angle arrived at 1/25 the structures still held enough carrying capacity. The beam-to-column connections with rubber cushion and bolt worked well and the failure pattern of the structures was ductile with column bending failure, and the displacement ductility factor was larger than 3.5. Finally, a nonlinear-elastic model was adopted to represent the jointed connection in numerical simulations of the structures. By comparing the results of tests and simulations, the nonlinear-elastic model was proved properly to represent this kind of jointed connection.
