ABSTRACT:
This composite beam structure is built up from at least two relatively rigid members, which may be of extruded aluminum and at least one relatively flexible web, which may be corrugated sheet aluminum. The web connects the relatively rigid members. The web has relatively short pitch, shallow corrugations in its margins to facilitate its connection to the rigid members, and relatively long pitch, deep corrugations between its margins to provide increased stress resistance. A box beam modification uses two relatively rigid members and two corrugated webs.
