The authors proposed a new type of shock absorber composed of steel pipes wrapped with rubber pipes. And static loading tests were conducted. As the result, it was confirmed that the shock absorber has sufficient energy absorbing capacity and can be used for shock absorbers. And a model to estimate the load-displacement characteristics of the shock absorber proposed was constructed. In this research, static loading tests were conducted again to confirm the validity of modeling the load-displacement characteristics, the dynamic response analysis of base isolated bridge attached with the shock absorbers was conducted, and the practical use and validity of the absorbers were proved.

提出了一种由钢管和橡胶管组成的新型减振器。并进行了静载试验。结果，确认了该减震器具有足够的能量吸收能力，并且可以用于减震器。建立了减振器载荷-位移特性的估算模型。再次进行了静载试验，验证了荷载-位移特性模型的有效性，并对安装减震器的基础隔震桥梁进行了动力响应分析，验证了减震器的实用性和有效性。
