微小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, lmprovement of seismic performance of structures comes to significant issues. Installing dampers to stmctures is recognized as one of effective measures decreasing seismic damage from pimary structures. Recently a bingham type damper has been noticed because of its predominant characteristics such as no dependence on both velocity and temperature. In this paper, the bingham dampers with newly composed materials are examined experimentally. Preferable combination between silicon oil and some fillers are found after the dynamic test changing the frequency from one to five Herz.
