A regular inspection of a bridge carrying U.S. Route 422 over the Schuylkill River in Berks County, Pennsylvania, revealed cracks in the floor beam–to–cantilever bracket tie plates. Similar fatigue damage of this type has been observed over two d

With the magnitude of some stress cycles in a live load stress range spectrum being higher than the constant amplitude fatigue limit (CAFL) of a structural detail, the development of a fatigue crack could be expected. The current procedure in the AAS

Fatigue strength of welded structures is typically estimated through several approaches, including experimental S-N curves, the hot spot stress approach, and fracture mechanics. Recent work on the local stress field singularity of the weld toe has pr

This paper compares the behavior of local buckling in trapezoidal rib orthotropic bridge deck systems. The primary objective of this paper is to compare the condition of a uniform stress pattern (column) and that of a non-uniform stress pattern (beam

High tensile weld residual stress is one important factor contributing to fatigue crack development even under reversal or compressive cyclic loadings. A compressive stress induced by post-weld treatment is beneficial by eliminating the tensile resid

Large-scale I-section beams were welded from A710 (HSLA-80) steel plates. There were plain welded beams, similar beams with two attachment details fillet welded to the tension flange, and similar beams with transverse groove welds. The welding proced
