Abstract: Among the major concerns of bridge engineers today are the fatigue damages that have been accumulated in riveted members and the safety of riveted structures. Many of these structures were fabricated and placed into service at the beginning of the century. How to determine the appropriate fatigue strength category for a riveted bridge member is not well defined. Better estimates of the fatigue resistance of riveted built-up members are needed. The paper reviews available data from past experimental studies, reports the results of recent tests of full-sized members, and recommends fatigue strength categories for evaluation of riveted bridge members.
