In　this　study,　a　comprehensive　experimental　and　theoretical　work　was　conducted　on　the　bending　performance　of　hybrid　carbon-polyethylene　terephthalate　(C-PET)　fiber-reinforced　polymer　(FRP)　strengthened　reinforced　concrete　(RC)　beams　with　U-strip　anchorages.　Eleven　RC　beams　were　tested　under　a　four-point　bending　load　to　investigate　the　influence　of　stacking　sequence　and　U-strip　anchorages.　The　bending　performance　of　strengthened　beams　was　carefully　examined　and　discussed　with　regard　to　failure　mode,　flexural　strength,　ductility　coefficient,　and　FRP　strain　development.　The　hybrid　strengthened　beams　with　U-strip　anchorages　exhibited　10.54　%-21.97　%　higher　flexural　strength　and　4.30　%-206.27　%　higher　ductility　factors　than　the　corresponding　strengthened　beams　without　U-strip　anchorages.　In　addition,　a　theoretical　analysis　model　with　high　accuracy　was　proposed　to　simulate　the　load-deflection　curves　of　the　strengthened　beams　based　on　the　section　analysis　and　plastic　hinge　model.　Finally,　this　paper　evaluated　the　accuracy　of　design　guidelines　(including　GB　50608,　ACI　440.2　R,　and　CNR　DT　200　R1)　in　calculating　the　load-bearing　capacities　of　strengthened　beams.
