滑動隔震橋樑之耐震分析

Abstract

本文探討滑動式隔震橋樑之耐震行為,包括鐵弗龍及摩擦單擺等隔震系統 之應用,由於地震來襲時並非固定於橋樑之軸向,為了能夠更真實地模擬橋 樑之受震行為 動力分析將考慮隔震橋樑之平面運動. In this thesis,the seismic behaviors of bridges isolated with sliding systems,including the Teflon bearing and the friction pendulum bearing,are investigated. Since in reality the impact -ing directions of the earthquakes are not necessary along the longitudinal direction of the bridge ,plan motions of the isol -ated are considered in the dynamic analysis.
