VIBRATION CONTROL STRUCTURE OF MEGA-FRAME

摘要

PROBLEM TO BE SOLVED: To provide a vibration control structure of a mega-frame skeleton capable of obtaining the high vibration control effect for high external force while controlling the deformation of a building for very low external force such as wind, weak earthquake or the like.;SOLUTION: The building 10 includes a mega-frame skeleton structure connecting the top of a core 16 to the top of the circumferential column 18 with a mega-beam 20. Low strength section 22 is provided to a connecting section between the mega-beam 20 and the circumferential column 18. An oil damper 26 is provided directly under the mega-beam 20. The low strength section 22 is deformed or destroyed when load exceeding predetermined weight is operated, and the displacement of the mega-beam 20 is allowed. When the displacement of the mega-beam 20 is made, the oil damper 26 functions to damp the displacement.;COPYRIGHT: (C)2002,JPO
