An　experimental　study　on　seismic　performances　of　two　precast　concrete　frame　connections　connected　with　the　prestressted　method　and　one　cast-in-place　concrete　connection　subjected　to　cyclic　loading　are　conducted.　In　order　to　provide　the　basis　data　for　establishing　the　aseismic　design　method　of　precast　concrete　frame　connections　connected　with　the　prestressted　method,　the　failure　pattern,　hysteresis　loop　curves,　displacement-restoring　capacity,　displacement　ductility　and　energy　dissipation　are　investigated.　The　studied　results　show　that　the　precast　concrete　frame　connections　connected　with　the　prestressed　method　are　equal　or　superior　to　that　of　the　cast-in-place　concrete　connection　on　seismic　performances.　It　is　also　shown　that　the　limit　deformation　and　the　displacement-restoring　capacity　of　the　former　are　better　than　the　latter.
