Abstract: A prefabricated load-bearing wall panel has a layer of concrete attached to a plurality of spaced apart parallel metal wall studs. The slab support is achieved by flexible bolsters secured at spaced locations to each stud and fastened to a reinforcing mesh embedded in the concrete slab. The bolsters, which are partially embedded in the slab, provide compressive and tensile support for the slab on the studs in a direction generally perpendicular to the general plane of the slab. In addition, the wall panel exhibits a synergistic effect in terms of composite design, wind load strength and shear strength.
