摘　　要：给出了有效预应力水平σpe不同时常规预应力混凝土梁板相对界限受压区高度的限值,为合理考虑预应力筋有效预应力水平对常规有粘结预应力混凝土梁板正截面承载力的影响提供依据。提出了FRP筋预应力混凝土梁板设计应遵循的原则和具体设计的方法。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.

关 键 词：预应力混凝土梁板 FRP筋 相对界限受压区高度
