PILE HEAD JOINT STRUCTURE, DESIGN METHOD OF PILE HEAD JOINT STRUCTURE AND DESIGN PROGRAM OF PILE HEAD JOINT STRUCTURE
To provide a pile head joint structure, which can reduce bending moment generated at the pile head in comparison with conventional pile head joint structures of rigid joint and suppress decrease in bending moment generated at the pile head in comparison with conventional semi-rigid pile head joint structures, and its design method and design program.SOLUTION: In a pile head joint structure which is composed of piles, anchoring bars joined to the pile heads of the piles, and pile caps that surround the pile heads and anchoring bars virtually without gaps, when the bending moment generated at the pile head at the maximum design axial force is defined as the maximum bending moment generated at the pile head and the bending moment generated at the pile head at the minimum design axial force is defined as the minimum bending moment generated at the pile head, the specifications of the piles and the anchoring bars are set so that the minimum bending moment generated at the pile head is 70% or more and 95% or less of the maximum bending moment generated at the pile head.SELECTED DRAWING: Figure 4
【課題】従来の剛接合とされている杭頭接合構造よりも杭頭発生曲げモーメントを低下させることが可能である一方、従来の半剛接合の杭頭接合構造よりも杭頭発生曲げモーメントの低下を抑制可能な杭頭接合構造、その設計方法、及び、その設計プログラムを提供する。【解決手段】杭、杭の杭頭部に接合された定着筋、並びに、杭頭部及び定着筋を実質的に隙間無く囲むパイルキャップによって構成された杭頭接合構造において、最大設計用軸力での杭頭発生曲げモーメントを最大杭頭発生曲げモーメントとし、最小設計用軸力での杭頭発生曲げモーメントを最小杭頭発生曲げモーメントとしたときに、最小杭頭発生曲げモーメントが最大杭頭発生曲げモーメントの７０％以上９５％以下になるように杭及び定着筋の仕様が設定されている。【選択図】図４
