摘要：

An　experimental　study　on　seismic　performances　of　five　beam-column　connections　subjected　to　reversed　cyclic　loading　was　conducted.　These　performances　included　failure　pattern,　hysteresis　characteristics,　displacement-restoring　capacity,　displacement　ductility　and　energy　dissipation.　The　objective　of　the　study　is　to　develop　guidelines　for　the　design　of　precast　prestressed　concrete　beam-to-column　connection　with　unbonded　tendons　for　regions　of　high　seismicity.　The　study　results　show　that　the　performances　of　precast　prestressed　beam-to-column　concrete　connections　with　unbonded　tendons　are　equal　or　superior　to　that　of　a　monolithic　connection.
