ABSTRACT:
A composite metal-concrete column or beam is described for use in building construction. It comprises (a) a pair of channel members fabricated of galvanized steel sheet, each channel member having a central web portion and first and second flanges substantially perpendicular to the web portion, the free edges of the flanges forming narrow lips substantially perpendicular to the flanges and the web portion having openings through which wet concrete may freely pass, the channel members being positioned in back-to-back spaced relationship with the flanges projecting outwardly, (b) panel members extending across between the flanges of each the channel member and held within the narrow lips and (c) concrete filling the space between the panel members and extending through and around the web portions, whereby the cured concrete and channel members form a strong, composite structure. The column can be used for a load bearing wall in building construction while the beam can be used in any location where a beam is required in building construction.
