Experimental Research on Seismic Performance of PHC Pipe Piles

Abstract:

Four prestressed high strength concrete pipe piles were tested under low cyclic loading, the failure characteristic, bearing capacity, ductility performance and hysteretic characteristic were analyzed. The research show that the bearing capacity and the ductility performance could be improved a lot by two measures of adding non-prestressed reinforcement and filling the pile core. The hysteresis loop of pile specimen adding non-prestressed steel bars is fuller, the energy dissipation capacity is larger, and the hysteretic behavior is better.
