In this paper, static and dynamic response analyses using a matrix method were systematically performed, in order to investigate the hysteretic behavior of prestressed concrete frames. On the basis of these analytical results, we presented a restoring force characteristics model for the prestressed concrete frames with different prestress levels. Furthermore, dynamic response analyses using this model were carried out, the parameters of which analyses were the cracking and yielding points on the envelope curve, the stiffness of the unloading curve and the natural periods with respect to the initial stiffness and to the secant stiffness at yielding. Taking these analytical results into consideration, an equation was proposed for predicting the substitute damping of the prestressed concrete frames.
