Claim Text:
1. An insulated composite structural wall panel comprising: a first concrete layer; a second concrete layer; an insulation layer disposed between the first and second concrete layers; a shear tie embedded in the wall panel and connecting the first concrete layer to the second concrete layer, the shear tie having a longitudinal axis, a base portion, and a plurality of longitudinally elongated anchor elements extending therefrom, the shear tie constructed of a non-metallic material that exhibits an elastic-plastic response to an applied shear load; each of the anchor elements having a length, an upper portion disposed in the first concrete layer, a lower portion defining a terminal distal end disposed in the second concrete layer, and an intermediate portion disposed in the insulation layer; a first flexural hinge formed in each anchor element at a first interface between the first concrete layer and the insulation layer; and wherein when a transverse shear load is applied to the anchor elements by lateral movement of the first or second concrete layers, the intermediate portion of each anchor element is transversely and angularly deformed in an elastic-plastic manner about the first flexural hinge within the insulation layer.
