免震装置を有する戸建住宅の免震効果に関する研究 : 免震装置としてすべり支承とダンパー支承を使った場合

Abstract

In this paper, the combination of new originated sliding isolator and damper isolator is used by the way of seismic isolator, the effects of base isolation of the detached house are analyzed for some strong earthquake motions. The effect of base isolation is very clear and the seismic shear coefficients of upper wooden structure are under 0.2 by strong earthquake motions of input earthquake level 25 kine, 50 kine and 75 kine. The maximum relative displacements of seismic isolator are under 20cm by strong earthquake motions of input earthquake level 25 kine and 50 kine.
