Horizontally Curved Steel I-Girders State-of-the-Art Analysis Methods

Abstract

Current AASHTO specifications pertaining to the analysis and design of horizontally curved bridges are based upon research work conducted prior to 1978. Since then a significant amount of work has been conducted to further advance analysis methods and to better understand the behavior of these complex structural systems. Unfortunately, the results of these various research efforts are scattered and, in some cases, unevaluated. This paper complements and updates survey articles published in 1968 and 1978 and presents highlights of the analytical work conducted on horizontally curved steel I-girder bridges.
