Beams – Bearing Simply versus Continuous Structural

Text in the illustration

continuous steel beam
4" min.
with a continuous steel beam, the bearing plate on top of the column has to be at least 4" long (and as wide as the beam)
column
simple steel beam
3-1/2" min.
with a simple steel beam, the bearing plate on top of the column has to provide at least 3-1/2" bearing for the ends of both beams resting on it (the bearing plate must also be as wide as the beam)

Generated explanation

The illustration compares column bearing requirements for continuous steel beams and simple steel beams using perspective and elevation views. The upper diagrams show a continuous I-beam passing over a column, with a bearing plate at least 4 inches long and as wide as the beam. The lower diagrams show two simple I-beams meeting end-to-end over a column, with the bearing plate providing at least 3-1/2 inches of bearing for each beam end and matching the beam width. Bolted connections are shown at the beam bottom flanges and column bearing plates.
