| Abstract: | Based on the experiments under low reversed cyclic loading,failure pattern,hysteresis curves,skeleton curves,restoring force model,displacement restoring capacity,ductility and rigidity degeneration of prestressed concrete beams with high PPR are studied systematically.And studies show that prestressed concrete beams with high PPR have good displacement restoring capacity,better ductility and seismic performance as a whole. |

| Keywords: | high PPR concrete beam seismic performance ductility rigidity degeneration |
