Steel Bridge Design Handbook: Splice Design

Typically it is not possible to fabricate, handle, ship or erect the entire length of a girder in one piece. In these cases, provisions must be made to splice multiple pieces of the girder together in the field to provide the required length. These splices must be capable of transmitting the shear and moment in the girder at the point of the splice. This module focuses on the factors which influence and the principles of the design of bolted field splices. Factors that influence field splice design and layout are presented, including span layout, curvature, and girder properties. General design provisions are also addressed in this module, including flexural resistance provided by a bolted field splice at the Strength and Service limit states, as well as detailing considerations. Lastly, a thorough design example of a bolted field splice for a steel I-girder is provided, illustrating calculations for flange and web stress, splice plate design, and bolt design. Strength, Service, and Fatigue limit states are considered, and design checks are provide for tension, compression, and shear resistance of splice plates, fracture and bearing resistance of splice plates, and strength and slip resistances of the bolted connections.
