Insulated structural panel connector

摘要

An insulated composite structural panel comprises a first concrete layer, a second concrete layer, and an insulation layer disposed therebetween. One or more shear ties are embedded in the panel. The shear ties include a base portion and a plurality of elongated anchor elements extending from the base portion. A portion of each anchor element extends through the first and second concrete layers and insulation layer. The tie is formed of a material exhibiting ductile elastic-plastic behavior under an applied shear load. In a non-limiting example, the tie may be formed of a fiber reinforced polymer. The tie is constructed and acts to form stable flexural hinges at the interface between the insulation layer and each concrete layer. During a shear load event, portions of the anchor elements within the insulation laterally deform in a ductile manner to keep the structural panel relatively intact.

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.
