The hysteresis performance of prestressed concrete(PC) member depends on many factors: such as amount and arrangement of prestressing steels, bond-slip performance between prestressing steels and grout and etc.. These factors were not considered properly in the hysteresis models of PC member contributed in the past. Especially the bond-slip characteristic between prestressing steels and grout has great influence on the feature of hysteresis loop of PC member. In spite of the importance, the models were not designed in consideration of the influence clearly. To solve this problem it is effective to use fiber models as a model which expresses bending behavior of PC beam cross section. This paper reports the influence of amount of prestressing steels and bond-slip characteristics between prestressing steel and grout upon response of PC frame structures and in the analysis the fiber model is employed as a spring which expresses bending behavior of PC cross section
