- Abstract
- This paper presents a systematic approach to the seismic nonlinear analysis and
retrofit strategies for existing bridges with isolation system using a retrofit state
function newly proposed in this study. A seismic retrofit scheme using sliding base isolation
systems was presented to reduce the seismic hazard for bridge structures. In this study,
two types of isolation systems such as lead rubber bearings and slinding isolators were
used. The behavior of sliding isolators was modeled by a triaxial interaction model.
And three types of earthquakes such as EI Centro, San Fernando, and the artificial were
used as earthquake ground exitations. Seismic response analyses of the bridge before and
after retrofit were effectively carried out by using a three-dimensional nonlinear seismic
analysis program. IDARC-Bridge. Also, this paper proposes a retrofit state function for
easily representing the efficiency of a retrofit scheme.
