THE BEHAVIOR OF WELDED HIGHWAY STRUCTURES
The primary purpose of this investigation was to study the economic and efficient use of welding for highway structures. This report summarizes the findings of this project, the scope of which includes the following five major topics. (1) Welded Reinforcing Bars. Investigations were made of various joint configurations, bar deformations, and the fatigue behavior of joints loaded within concrete beams, loaded axially within concrete blocks, and the welded bars loaded axially. (2) Weld Inspection and Quality Control. An evaluation was made of existing inspection practices, and suggestions were formulated for the development of welding inspection specifications. (3) Fatigue Behavior of Welded Joints. This investigation yielded S-N diagrams and Modified Goodman Diagrams for transverse butt welds in a low allay steel. Observations that weld geometry had a considerable effect on the fatigue transverse butt welds in a low alloy stee. Observations stages of the investigation. (4) Effect of Geometry on Fatigue Behavior. This study considered the geometry effect on the fatigue behavior of butt-welded connections by using both machined steel specimens and welded joints. A finite-differences determination of the stress concentrations produced by idealized weld geometries has been completed. (5) Fatigue Data Bank and Data Analysis Investigation. Information from 25,000 tests was accumulated and a computer program was developed for analysis of the data.
