OVERVIEW
In this section, the term connections is used in a general sense to include all types of joints in structural steel made with fasteners or welds. Emphasis, however, is placed on the more commonly used connections, such as beam-column connections, main-member splices, and truss connections.
Recommendations apply to buildings and to both highway and railway bridges unless otherwise noted. This material is based on the specifications of the American Institute of Steel Construction (AISC), "Load and Resistance Factor Design Specification for Structural Steel Buildings," 1999, and "Specification for Structural Steel Buildings Allowable Stress Design and Plastic Design," 1989; the American Association of State Highway and Transportation Officials (AASHTO), "Standard Specifications for Highway Bridges," 1996; and the American Railway Engineering and Maintenance-of-Way Association (AREMA), "Manual," 1998.
5.1 LIMITATIONS ON USE OF FASTENERS AND WELDS
Structural steel fabricators prefer that job specifications state that "shop connections shall be made with bolts or welds" rather than restricting the type of connection that can be used. This allows the fabricator to make the best use of available equipment and to offer a more competitive price. For bridges, however, standard specifications restrict fastener choice.
High-strength bolts may be used in either slip-critical or bearing-type connections (Art. 5.3), subject to various limitations. Bearing-type connections have higher allowable loads and should be used where permitted. Also, bearing-type connections may be either fully tensioned or snug-tight,...
