Open Issues in the Seismic Design and Assessment of Bridges

Chapter
Part of the Geotechnical, Geological, and Earthquake Engineering book series (GGEE, volume 17)

Abstract

The chapter presents an overview of recent research on the seismic assessment/retrofit and design of bridges, focussing on some of the aspects which are still not adequately covered in the codes. These are: The level of protection to be provided when upgrading an existing bridge, and in particular whether this should be differentiated between new designs and retrofit of existing bridges; The appropriate methods of analysis and modelling, with emphasis on the scope of nonlinear static methods and to the problems related to the selection of the input for dynamic analysis; Soil-foundation-structure interaction and non uniform support input, representing two controversial issues that may be mature for an inclusion in routine bridge analysis.
