Abstract:The effect of prestressed degree on seismic performance of prestressed concrete pier is studied. The plastic hinge properties is gotten by means of reinforce bilinear model and concrete Kent-R. Park model. The plastic hinge hysteresisloop is obtained by setting kinds of prestressing tendons. The result of analysis indicates that the prestressed concrete pier can bear larger limit moment and more large dissipation energy ability than common concrete pier. Within the limit of concrete crushing strength, with the increase of prestressed degree, its relative limit moment of the prestressed concrete pier rises, and dissipation energy ability rises.
