Seismic Design of Bridges is a comprehensive set of 12 papers presented in Code and Commentary form. It sets out the recommendations of the Bridge Committee of the New Zealand National Society for Earthquake Engineering. The papers are aimed at experienced designers and authorities setting design standards. The procedures recommended are based on the present state of the art and represent good design practice in accordance with the latest developments in earthquake engineering as applied to bridges. Subjects discussed include: design philosophy, seismic loading and ductility demand, capacity design principles
and practice for ductile structures, a semi-emperical approach for structures of limited ductility, ductility capability and detailing for ductility, structural and non-structural details, bridge foundations, earth
 retaining structures, mechanical energy dissipating devices, dynamic analysis, structures requiring special studies and strengthening for seismic loads.
