Response spectrum calculated by linear analysis using actual seismic waves is different from response spectrum of seismic design for the range of long period. In addition, friction isolator is expected to absorb seismic energy. This effect should be utilized positively in seismic design. However, seismic isolation effect depends on the friction characteristic of system. Therefore, adjustment of frictional force becomes very important. This paper shows Friction Response Spectrum for long period by the synthetic seismic wave using design spectrum. The Friction Response Spectrum is able to obtain the optimum frictional force of seismic isolation instead of non-linear analysis and estimate response magnification of long period system with friction. Moreover, equivalent damping ratio is estimated from Friction Response Spectrum for long period system. Equivalent damping ratio can easily calculate response of friction system., rights: 社団法人日本機械学会 rights: 本文データは学協会の許諾に基づきCiNiiから複製したものである relation: IsVersionOf: http://ci.nii.ac.jp/naid/110006317489/, text, application/pdf}, pages = {1699--1704}, title = {長周期摩擦系応答スペクトルに関する研究(機械力学, 計測, 自動制御)}, volume = {73}, year = {2007}, yomi = {ワタナベ, テツヤ and タナカ, キハチロウ} }
