Abstract
The objective of this study is to provide detailed information on the retrofit
design of reinforced concrete bridges. Several retrofitting techniques that can be
easily implemented in countries with high seismic risk, such as Greece, are
presented. Special emphasis is given on the retrofit of bridge piers using steel
jackets, reinforced concrete jackets and composite material jackets. Furthermore,
several techniques for the retrofit design of superstructure are discussed. A
comparison between traditional and new retrofit methods is made in order to
rationalize the increase in demand for use of recently developed retrofitting
techniques. A design example is also included in this study. The example focuses
on the retrofit design of a bridge pier using either a fiberglass-epoxy or a carbon
fiber-epoxy composite jacket. As an altern
