It　is　commonly　accepted　that　addition　of　infilled　masonry　walls　(1MW)　could　enhance　the　in-plane　strength　and　stiffness　of　RC　frame　buildings　subjected　to　seismic　loads.　However,　once　the　1MW　walls　failed,　the　shear　force　initially　resisted　by　the　IMW　has　to　be　transferred　to　the　surrounding　frames　and　may　incur　shear　failure　to　the　frames.　Despite　the　extensive　studies　carried　out　in　the　past　decades,　studies　on　the　structural　performance　of　masonry　infilled　precast　concrete　(PC)　frames　are　few.　In　this　study,　eight　half-scaled　single-story　one　bay　frame　were　tested　subjected　to　seismic　loading,　including　three　reinforced　concrete　(RC)　frames　and　five　PC　frames.　The　investigated　PC　frames　deviates　the　beam　potential　plastic　hinge　zone　away　from　beam-to-beam　connection　region.　The　variables　investigated　in　the　tests　included　the　types　of　opening　in　masonry　infill　walls　and　the　types　of　cast-in-place　concrete　at　the　connections　(normal　concrete　or　steel　fiber　reinforced　concrete).　Results　indicated　that　the　investigated　PC　construction　method　has　minimal　effects　on　inelastic　behavior　and　ductility　of　bare　and　infilled　frames.　However,　the　PC　construction　method　may　affect　the　crack　development,　especially　at　the　interfaces　in　between　precast　and　cast-in-place　concrete　surfaces　in　the　region　of　the　connection.　However,　the　load　resisting　capacity　and　ductility　was　insensitive　to　the　usage　of　steel　fiber　reinforced　concrete　at　the　connections,　especially　for　bare　frames.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
