本文报道了地下钢筋混凝土桩反应特性的试验和分析研究结果。试验结果表明，桩顶轴向荷载影响桩的恢复力衰减，桩的最大破坏点取决于桩与周围土体的相对刚度。从使用三维有限元分析的分析研究中，实验行为可以通过所应用的方法充分模拟。今后将该方法应用于整个结构-桩基-土系统的抗震性能评价时，需要进一步研究滞后环的形状或面积。
This paper reports the results of experimental and analytical investigation on the response behavior of reinforced concrete piles under ground. From the experimental results, it was clarified that the axial load at pile head affects the restoring force degradation and the maximum damage point is dependent on the relative stiffness between the pile and surrounding soil. From the analytical study using 3-dimensional FEM analysis, the experimental behavior could be adequately simulated by the applied method. Further investigations on the shapes or areas of hysterisis loops will be needed for the future application of this method to seismic performance evaluation of the entire structure-pile foundation-soil system.
