ABSTRACT:
Composite framing members for use in building construction include reinforced concrete columns and beams surrounded by a pair of steel shells. A layer of protective material is applied to the interior surface of at least one shell prior to assembly of the shell to provide the final integrated framing member with superior insulating or fire resistance and survivability characteristics. Additionally, the steel shells impart greater structural strength and integrity than the reinforced concrete columns and beams could alone. Furthermore, the concrete cores, aided by the protective coating, function as a heat sink, absorbing heat and allowing the entire framing member a longer structural life that it would have if the steel or concrete were used alone.
