非線形型粘弾性ダンパーを有する間柱型制振架構の減衰性能評価と動的挙動

摘要

In this paper, the results of studies on the damping characteristics evaluation and the dynamic behavior of the vibration damping system in which the nonlinear viscoelastic damper is installed in a frame with a stud type were shown. It became clear, that the damper can be modeled with high precision by using the three elements model, the effective damper deformation ratio depends on the nonlinear characteristics of the damper, and the loss displacement of the damper depends on the rotational deformation. In addition, damping effect of the damper in a building model and efficient installation method were shown.%近年，地震動や風などの外乱によつて建物に生じる振動エネルギ 一を吸収することを目的として，制振装置の普及が進んでいる。特 に，外部エネルギーを必要としないパッシブ制振は簡易な機構で比 較的低コストであることから，多種多様な装置が開発され実用化に 至っている。
