建物の自重に起因する柱軸力とPC鋼棒の初期張力によって柱脚は基礎梁に圧

建物の自重に起因する柱軸力とPC鋼棒の初期張力によって柱脚は基礎梁に圧着され，初期の段階で柱梁は離間せず一体として挙動し，柱脚回転角は0である．また，このときの柱と基礎梁を含めた，全体の曲げ剛性は，柱と基礎梁が剛接合されているときの曲げ剛性と等しい．

By pretension PC steel bar and axial force due to the weight of the building bases the Foundation beams crimp without spaced columns and beams are in the early stages, and together as a behavior, rotation angle of the pillar base is 0. Also, bending stiffness of the whole, including the columns and beams, pillars and beams are rigid joint when bending, stiffness and equal.

The column base by the initial tension of the pillar axis force and PC steel bars due to its own weight of the building is crimped to the foundation beams, columns beams at an early stage behave as an integral without separated, the column base rotation angle is 0. Also, including the pillar and foundation beams in this case, the overall bending stiffness is equal to the flexural rigidity when the pillars and underlying beams are rigidly joined.
