Fatigue of Curved Steel Bridge Elements - Ultimate Strength Tests of Horizontally Curved Plate and Box Girders

摘要

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.
