VIBRATION CONTROL STRUCTURE FOR LARGE-SPAN FRAME BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a vibration control structure for a large-span frame building that can improve vibration control performance of suspension objects such as a floor slab, a beam, and a ceiling arranged inside in a suspension support state, and can suitably securing habitability in a living room even when a living floor is constituted by the suspension objects.;SOLUTION: There is provided a vibration control structure B for a large-span frame building that includes a suspension object 2 suspended from an upper structure 1 to be supported. The vibration control structure includes: a brace material 4 provided obliquely while having a lower end connected to the suspension object 2; and a rotary inertia mass damper 6 and a spring member 7 arranged in series as an additional vibration system 8 between an upper end of the brace material 4 and the upper structure 1 so as to connect the brace material 4 to the upper structure 1, cycles of the additional system 8 being synchronized with cycles of the upper structure 1.;COPYRIGHT: (C)2014,JPO&INPIT
