Tag: Composite Columns Composite columns and frames

When the stanchions in steel frames were first encased in concrete to protect them from fire, they were still designed for the applied load as if uncased. It was then realized that encasement reduced the effective slenderness of the column, and so increased its buckling load. Empirical methods for calculating the reduced slenderness still survive in some design codes for

Tag: Composite Columns Criteria for Composite Construction

In composite construction, a steel beam and a concrete slab act together to resist bending. The slab, in effect, serves as a cover plate and allows use of a lighter steel section. The AISC ASD and LRFD specifications for structural steel buildings treat two cases of composite members: (1) totally encased members that depend on the natural bond between the
