摘要：The effects of the prestressed tendon reinforcement ratio,the ordinary
   longitudinal reinforcement ratio and the stirrup reinforcement ratio on
   the hysteretic behavior and seismic characteristics of the prestressed
   concrete bridge pier have been obtained with the fiber model analysis
   method.The analysis results show that for the prestressed concrete
   bridge pier:the greater the prestressed tendons reinforcement ratio and
   the ordinary longitudinal reinforcement are,the more obvious the pier's
   hysteresis looppinching effectis,the smaller the residual displacement
   is, the lower the energy dissipation capacity is;and the greater the
   stirrup reinforcement ratio is,the larger the hysteresis loop area
   is,the better the ductility of bridge piers is,the greater the shear
   capacity is.The research results will provide a theoretical basis for
   the hysteretic behavior analysis of the prestressed concrete pier.
