SEISMIC-RESPONSE CONTROLLED STRUCTURE OF LIGHTWEIGHT STEEL-FRAMED HOUSE

摘要

PPROBLEM TO BE SOLVED: To provide a seismic-response controlled structure which can reduce the deformation of a building by efficiently converting vibrational energy, generated by earthquakes, into thermal energy. PSOLUTION: In an area R1 on the upside of a middle rail 4 of a framework frame 1, a first damper unit D1 with first-fourth viscoelastic dampers 5a-5d is mounted. In an area R2 on the downside of the middle rail 4, a second damper unit D2 with fifth-eighth viscoelastic dampers 5e-5h is mounted. Additionally, in the framework frame 1, the mounting rigidity of each mounting part of the first-eighth viscoelastic dampers 5a-5h, the storage rigidity of each of the first-eighth viscoelastic dampers 5a-5h, and the loss coefficient of each of the first-eighth viscoelastic dampers 5a-5h are adjusted to satisfy predetermined conditions, when a story deformation angle is 1/200 rad in horizontal deformation.
