FATIGUE OF CURVED STEEL BRIDGE ELEMENTS-ULTIMATE STENGTH TESTS OF HORIZONTALLY CURVED PLATE AND BOX GIRDERS

The research reported herein is part of a 5 year multiphase investigation involving extensive analytical and experimental studies of horizontally curved steel plate and box girders. The project, which began in 1973, is entitled "Fatigue of Curved Steel Bridge Elements". The work is sponsored by the FHWA and was carried out in Fritz Engineering Laboratory at Lehigh University. This report presents the results of the ultimate strength tests of one curved non-composite plate girder assembly, two curved composite plate girder assemblies and two curved composite box girders. The primary objectives of the research reported herein are: (1) to determine the load-deflection behavior of large size curved plate girder assemblies and curved box girders which are loaded to ultimate strength, and (2) to compare the experimental behavior with analytic predictions. This study is of very limited scope and is intended only as a pilot study of the ultimate strength of curved plate and box girders. The study was conducted primarily because the test girders were available and could be retrofitted following the fatigue tests. (FHWA)
