Book Description
This research (which is the second phase of a study intended to provide reliable information on fatigue behavior of steel bridge members), and an extensive investigation of fatigue effects in welded steel beams, which formed the basis for recommendations for revision of the fatigue provisions of the AASHP Standard Specifications for Highway Bridges. A hundred and fifty seven steel beams and girders were fabricated and tested to define the fatigue strength of various structural details, including stiffeners and attachments. Stress range was observed for nearly all the variation in cycle life for all stiffener and a attachment details examined in this study.

Book Description
The paper summarizes some of the findings of a comprehensive study on the fatigue strength of rolled and welded built-up beams without attachments, rolled and welded beams with cover plates, and welded beams with flange splices. Altogether, 374 steel beams with two or more details were fabricated and tested. The welded beam details discussed herein represent the upper and lower boundaries of fatigue behavior of welded beams. The lower bound is provided by beams with partial length cover plates - a severe notch producing details. For purposes of design, this study has shown that the fatigue strength of the upper and lower bound details is independent of the strength of steel. A36, A441 and A514 steel beams provided the same fatigue strength for a given detail, and stress range was observed to account for nearly all the variation in cycle life. The paper reviews briefly the major variables that influence the fatigue strength of welded details and suggests how they should be considered in design. (Author).

Book Description
The fatigue behavior of welded steel beams is evaluated using the fracture mechanics concepts of stable crack growth. A fracture mechanics model for cracks originating from the pores in the web-to-flange fillet weld is developed. Esstimates of the stress-intensity factor are made that numerically describe the initial flaw condition. With the final crack size known, a theoretical crack-growth equation was derived from the fatigue test data of the welded beams. The derived relationship compares well with actual crack-growth measurements on a welded beam and available data from crack growth specimens. (Author).
