PURPOSE:To increase a restoring force to its original shape from bending deformation of a pile, by a method wherein high strength profile steel rods, having a specified yield point stress, are arranged parallel to PC steel rods to cast them in a concrete pile. CONSTITUTION:High strength profile steel rods 5, having yield point unit stress of SD35 or SD35 or more, and PC steel rods 4 are alternately arranged parallel to each other, the steel ratio of the profile steel rod 5, arranged in the vicinity of a portion, on which maximum moment is exerted, is set to 1.8% or more, and winding reinforcement is arranged around the two steel rods 4 and 5. Thereafter, the two steel rods 4 and 5 and the winding reinforcement 3 are cast in concrete 2 to form a composite reinforced pile 1. |
