FATIGUE PHENOMENA IN WELDED CONNECTIONS OF BRIDGES AND CRANES

The report presents the results of a statistical analysis of all the fatigue tests carried out by the Committee Members using the method of maximum likelihood. Design procedures for the principal types of welded connections used in bridge work are outlined together with recommendations for their application to the weldments of smaller structures. The report also includes the method of dealing with the variable amplitude loading experienced by bridge members under service conditions, using the rain-flow method of cycle counting and the Palmgren-Miner hypothesis of cumulative fatigue damage.
