摘　　要：从理论和具体的数据对部分预应力混凝土构件的钢筋应力进行分析，当对构件预应力钢筋的张拉应力值σｃｏｎ不同时，就对构件中的预应力钢筋和非预应力钢筋的应力分配产生影响，从而探讨此类构件的可靠度；并对设计此类构件提出建议。The stress states of partially prestressed concrete members are analyzed,It is shown that the different values of prestressing stress σ con have different effects on the distribution of stress between prestressing steel and non prestressing steel.The reliability of partially prestressed concrete members are discussed,and then some designing suggests are presented for the members
