Analysis of seismic isolation due to rocking piers in bridge structures using three-dimensional finite element modelling

Emma Jane Leitner

    Research output: ThesisDoctoral Thesis

    Abstract

    A relatively new method of seismic isolation in bridges allows the uplift and rocking of bridge piers, reducing damage to the bridge, hence reducing down-time after an earthquake and associated costs. This study generates three-dimensional finite element models using the software package ANSYS, firstly with single column models under quasi-static cyclic loading, and secondly with full bridge models undergoing earthquake loading, both utilising pre-cast concrete construction and FRP wrapping. Special focus is given to the representation of concrete damage, methods of increasing energy dissipation of the system, and the influence of rocking piers on pounding behaviour in the bridge superstructure.
