| Abstract: | The limit values of concrete relative depth of limiting compression zone in common prestressed concrete beams and slabs were given with the variation of effective prestress level σpe,which provides basis for rationally considering the effect of effective prestress level of prestressed reinforcement to normal section bearing capacity of common bonded prestressed concrete beams and slabs.The reqired principles and detailed design method in design of prestressed concrete beams and slabs with FRP bars are presented. |

| Keywords: | prestressed concrete baems and slabs FRP bars relative depth of limiting compression zone |
