Riveted And Bolted Structural Joints

Report of an Investigation Conducted in The Department of Civil Engineering, Engineering Experiment Station, University of Illinois in cooperation with The State of Illinois, Division of Highways and The U.S. Department of Transportation, Federal Highway AdministrationThe Illinois Cooperative Highway Research Program, Project IHR-5 was initiated at the University of Illinois in 1947. Since then numerous investigations have been conducted on the behavior of reveted and bolted structural connections, the results of which have been reported in reports and papers in the technical literature. This report presents a brief summary of these studies in the form of quoted or abstracts from the published papers. The paper themselves must be examined for the details of the investigations. Finally, a brief summary is presented of the applications of the research in the design specifications for riveted and bolted structures. The research has covered a wide variety of studies which relate to the behavior of riveted or bolted members or connections. Briefly the studies fall into the following topics. A. Riveted Connections: a. Effects of bearing pressure on the static fatigue strength of connections. b. Static strength of various structural members - Flat plates, rolled sections, and built-up truss-type members. c. Strength of the fasteners - In tension, shear, and combined tension and shear. B. Bolted Connection: a. Strength of various structural members (fatigue and static strength) - Flat plates, rolled sections, and built-up truss-type members - beam to column or stringer-to-floor beam connections. b. Strength of fasteners; bolts (A325 and A490), nuts and washers. - In tension, shear, and combined tension and shear. C. Field Tests of Bridges. Based on results of these studies, many changes have been made in design procedures and design specifications; the riveted and bolted structures designed on the basis of the research findings will be safer and provides for more efficient use of the materials than would otherwise have been possible.project IHR-5; Illinois Cooperative Highway Research Program Phase
