    Abstract:

    To investigate the seismic performance of precast frame-shear wall structures comprised of cast-in-place concrete shear walls and prefabricated frame components,two 1/2 scale test specimens were fabricated and carried out under quasi-static reversed cyclic lateral loading in laboratory.One specimen named PCFW1 is a precast structure comprised of cast-in-place concrete shear walls and prefabricated frame components,and the other one named RCFW is a conventional cast-in-place concrete one,which is used as a reference specimen,all two test specimens are two bay-two story RC specimens.Some important characteristics such as failure process,failure mechanism,hysteretic response,displacement ductility,energy dissipation capacities and plastic hinge development process were studied.The test results show that the test specimen PCFW1 have similar failure mode compared with the test specimen RCFW.The lateral load-displacement hysteretic loops of both specimens are plump.The characteristic values of bearing capacity such as yield load,peak load,and ultimate load of specimen PCFW1 are larger than those of RCFW,but the difference is less than 10.0%.The displacement ductility of specimen PCFW1 is obviously less than that of RCFW;Grout-filled sleeves can transmit the longitudinal steel stress efficiently;The anchor bars in a knee connection in the top story can be replaced by bars wielded with anchor plate in precast shear wall-frame structures comprised of cast-in-place concrete shear walls and prefabricated frame components.
