This　test　research　3　hybrid　precast　unbonded　post-tensioned　concrete　beams　under　reversed　cyclic　loading.　Such　parameters　as　PT　initial　post-tensioning　load,　full　grouted　mild　steel　strength　and　area　are　described.　Experiment　shows　that　these　beams　used　hybrid　precast　method　can　improve　the　energy　dissipation　and　bearing　capacity　of　specimens　than　others.　The　hybrid　precast　specimens　still　have　desirable　seismic　characteristics　such　as　a　self-centering　capability　and　an　ability　to　undergo　large　nonlinear　displacements　with　little　damage.　Resilience,　ductility,　energy　dissipation　of　specimens　are　analyzed.　The　study　was　initiated　to　provide　data　for　the　development　of　a　rational　and　economical　design　and　construction　procedure　for　such　connections　in　seismically　active　regions.
