微少粉体とオイルを混合したビンガムダンパーの耐震性能実験

Abstract

Since Hyougoken-nanbu Earthquake in 1995, improvement of the seismic performance of the structures comes to significant issues and installing dampers to the structure is recognized to be effective decreasing seismic damage of essential structures. Recently bingham type damper has noticed because of its predominant characteristics, in which no dependence on both velocity and temperature. In this paper, the bingam dampers with newly composed materials are examined experimentally and preferable combination between silicon oil and some filler is found after the dynamic test changing the frequency from one to five Herz.
