ABSTRACT:
An elongated structural member, which is suitable for use as a joist, beam, girder or the like, comprises first and second webs, each having a generally arcuate cross-sectional shape and, thus, one convex surface and an opposing concave surface. The webs are disposed in generally mutually parallel relation with their respective convex surfaces in confronting relation, one diverging from the other in both an upper region and a lower region. A wedge is interposed between, conforms to, and is intimately joined to the confronting convex surfaces of the webs in at least a portion of each of the upper and the lower regions. The webs are made of plywood and the wedges are made of solid wood. The wedges are capable of bearing substantial compression and tension loads so that together with the portions of the webs to which they are intimately joined, they can accept and support great loads on the member when mounted in span. More particularly, each wedge has a tension or tensile strength on the order of at least 950 pounds per square inch and a compressive strength on the order of at least 950 pounds per square inch.
