Connection

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.
