Abstract:
In order to investigate the effect of the pile ’s diameter,pile body ’s effeetive prestress and configu-ration of a certain number of non prestressed reinforcement on seismic behavior of PHC pile,five PHC pileswere tested under low cyclic loading. The damage characteristic,bearing capacity, hysteretic curve and duc-tility were analyzed. It is shown that the seismic performance of PHC pile was reduced with the increase of thepile’s diameter and with the improvement of pile body’s effective prestress. The configuration of a certainnumber of non prestressed reinforcement can effectively improve the level of the pile ’s seismic performance.
