Bolted end-plate connection is a kind of field joint frequently used in steel frame construction. Some types of this connection for the steel frame structures with I-shaped cross-sections are introduced. The possible failure modes of this connection under loads are analyzed. The design expressions to calculate the tension of the bolts and the thickness of the end-plate are given. The requirements for design of the connection welds and calculation of the local strength of web at connected parts of members are discussed.
