The failure of welded structures by fatigue can be viewed as crack growth between two flaw sizes forming fixed boundary conditions. The initial condition is a rapidly initiated or pre-existing flaw, and the terminal condition is the critical flaw at failure. This report outlines the modes of failure and methods of analysis for fatigue design for structural steels ranging in yield strength from 30 to 300 ksi. Fatigue crack propagation characteristics of steels seldom vary widely in response to broad changes in yield strength and fracture toughness. However, strength and toughness do vary widely among structural steels and thereby exert profound effects on the fatigue failure process. By applying the principles of the NRL Ratio Analysis Diagram, an analysis shows that the ratio of plane strain fracture toughness to yield strength can be employed to determine fatigue design procedures.

The brittle fracture of the Hoan Bridge in December 2000 highlighted the fracture susceptibility of details containing intersecting welds in steel bridges. Though it is now known that details with intersecting welds should be avoided, many existing bridges in Indiana contain details with intersecting welds. Little experimental data on the fatigue performance of these details exists. The purpose of this study was to evaluate the fatigue strength of several details commonly found in steel bridges in Indiana that contain intersecting welds. Large-scale experimental fatigue testing were performed using nine steel beams to study the behavior of three basic types of welded details: a vertical stiffener, a horizontal stiffener terminating near a vertical stiffener, and a horizontal gusset plate coped to fit around a vertical stiffener. The welded details in this study were fabricated with varying degrees of web gap, defined as the distance between perpendicular weld toes. The results of the experimental testing were examined and compared to prior testing to determine if the size of the web gap affected the fatigue strength. Furthermore, the performance of drilled hole retrofits used to extend the fatigue life of these details was studied. Within the scope of the fatigue testing program, the presence of intersecting welds was not found to significantly affect the fatigue strength of vertical stiffener and horizontal gusset details. However, the size of the web gap may have had an effect on the fatigue strength of details where a horizontal stiffener terminated near a vertical stiffener. Further experimental testing is needed to more clearly define the relationship between web gap and fatigue strength for this case. Drilled hole retrofits were successful at prolonging the lives of these details to varying degrees, but it should be noted that the stress redistribution resulting from these holes may cause fatigue cracking at nearby weld toes.

Brittle Fracture in Steel Structures emphasizes the prevention of brittle fracture in structures fabricated from mild and low alloy steel operating at normal ambient temperatures. This book is divided into seven chapters. Chapter 1 provides the historical background and summarizes numerous case histories of brittle fractures. The nature of the phenomenon and factors that influence brittle fracture, including various methods of testing to determine the notch ductilities of different steels are described in Chapters 2 to 4. The fifth chapter elaborates the design considerations affecting the choice of steel for structural applications. Chapter 6 reviews the main methods for assessing the degree of notch ductility needed for different applications, while Chapter 7 deliberates practical procedures, recommended by the Navy Department Advisory Committee on Structural Steels, for assessing the suitability of different steels for particular applications. This publication is beneficial to metallurgists and welders intending to acquire knowledge of mild steel structures fabricated by welding from rolled steel plates and sections.
