VIBRATION DAMPER FOR VISCOUS SYSTEMS
To provide a vibration damper for viscous systems capable of easily and reliably checking whether or not a disconnection pin has been cut with a simple configuration.SOLUTION: The vibration damper for viscous systems includes a disconnection pin 68 that horizontally connects a mounting plate and a viscous damper and has a constricted portion 67 configured so as to, when a certain level of horizontal force is generated on the mounting plate against a bottom wall plate, be broken to release the horizontal connection between the mounting plate and the viscous damper. The vibration damper includes: an accelerometer 111 that is placed in an office building 6 for observing the vibration acceleration acting on the office building as detection means 110 for detecting disconnection of the constricted portion; and Fourier analysis means 112 to which the vibration acceleration observed by the accelerometer is input, and which performs a Fourier analysis of dominant frequencies of the office building.SELECTED DRAWING: Figure 2
【課題】連結解除ピンが切断されたか否かを、簡単な構成でありながら、容易かつ確実に確認することが可能な粘性系の振動減衰装置を提供する。【解決手段】取付板と粘性ダンパーとを水平方向に関して連結していると共に底壁板に対して取付板に一定以上の水平力が生じると切断されて取付板と粘性ダンパーとの水平方向に関する該連結を解除する括れ部６７を有した連結解除ピン６８を具備した粘性系の振動減衰装置において、括れ部の切断を検知する検知手段１１０として、事務所ビル６に設けられ、事務所ビルに作用する振動加速度を観測する加速度計１１１と、加速度計で観測された振動加速度が入力され、事務所ビルの卓越周波数のフーリエ解析を実行するフーリエ解析手段１１２とを備えた。【選択図】図２
