New contributions to the international workshop on the seismic and retrofitting of reinforced concrete bridges Bormio, Italy, April 2-5, 1991

Abstract

The main objective of the workshop was to provide a critical comparison of the current state-of-the-art and of the practice in reinforced concrete bridge seismic design and retrofitting between the main seismically active regions. A secondary objective was to produce a clear statement of research needs and to propose possible international research cooperation. Four points of view were to be considered and compared, according to a geographical base which also corresponds to different design philosophies: the European, American, Japanese and New Zealand approaches were to be discussed. Emphasis was to be put on discussion of unresolved differences between different design and research practices. The workshop was organised in four sections, dealing with (1) basic concepts, (2) detailing, (3) examples of application, and (4) retrofitting. Each section was to consist of a presentation from each of the groups involved and an in-depth discussion session.
