An elongate, long-span transition beam employable between columns in a building frame structure. This transition beam includes (a) an elongate central portion having one, principal cross-sectional vertical depth, and (b) joined to the opposite ends of the central portion, a pair of elongate end portions each having a smaller cross-sectional vertical depth. These end portions may be formed with flange-modified reduced beam sections to act as "overload fuses". The central and end portions join through size-differentiated, transverse cross section, transitional regions which are formed adjacent opposite ends, and as parts, of the central portion. |
