It rises in urgent slant face area and the building where fundamental level differs largely it rises directly

摘要

PROBLEM TO BE SOLVED: To provide a foundation structure for preventing a decline of earthquake resistant safety of a slope and a building by difference in a foundation level of the building built on the steep slope and having great difference of several portions of stories in the foundation level. ;SOLUTION: A foundation section 2 on the lower side of the foundation level is set on the ground 4 under the slope as a direction foundation, and a foundation section 3 on the higher side thereof is set on the ground 5 on the slope by using a rigidity adjusting mechanism. By setting a rigidity value of the rigidity adjusting mechanism 8, horizontal force at right angles to the slope inputted in the foundation section 3 on the slope is reduced, and torsional vibration of the building is prevented by horizontal force in the direction parallel with the slope to reduce couple acting on the foundation section 3 on the slope resulting from the torsional vibration.;COPYRIGHT: (C)2003,JPO
