ABSTRACT:
A two-span wall panel construction includes a plurality of spaced, horizontal structural girts with liner panels secured between each three adjacent girts. Horizontally extending subgirts are attached to the liner panels and exterior panels are secured to the subgirts. The exterior panels are corrugated and mounted so that the corrugations extend parallel to the vertical structural columns. A plurality of notches is located on the outer surface of the exterior panel. The notches are aligned midway between the horizontal structural girts and can be varied in depth to cause the exterior panel to fail at the notch when subjected to a predetermined external load. Additional notches can be positioned on the inner surface of the exterior panel in alignment with the other notches. The adjacent, vertical liner panels are positioned in slightly spaced relationship at the end girts and the exterior panels are positioned in overlapping and unattached relationship at the end girts. Clips for holding the liner panels are secured to the end girts between the adjacent liner panels. These clips have angular flanges which pinch the adjacent liner panels against the end structural girts. External forces of predetermined magnitude cause the liner panels to deform about the middle girt as the liner panels pivot about and release from the clip flanges. Simultaneously, the overlapping exterior panels yield at their notched portions, release at their overlapping ends, and deform about the middle girt.
