通过对4根预应力高强混凝土(PHC)管桩进行低周往复荷载作用下的抗震性能试验研究,分析在桩身填芯、配置非预应力钢筋等措施对管桩的破坏形态、滞回性能、骨架曲线、延性性能以及刚度退化的影响。研究表明:桩身填芯可以改善管桩的变形能力;在管桩中配置一定数量的非预应力钢筋能够显著提高管桩的极限承载能力,对改善管桩的滞回性能、延性性能以及耗能能力效果更为显著。 Through the experimental research on the seismic performance of 4 prestressed high strength concrete (PHC) tubular piles under low cyclic reciprocating loads, the damage morphology, hysteretic behavior , Skeleton curve, ductility, and stiffness degradation. The results show that pile core filling can improve the deformation capacity of pipe piles. Assigning a certain amount of non-prestressed reinforcement in pipe piles can significantly increase the ultimate bearing capacity of pipe piles. It is significant to improve the hysteretic behavior, ductility and ductility of pipe piles Ability to effect more pronounced.
