Controlled destructive panel assembly

A wall panel construction comprising:

• A. a plurality of spaced, horizontal structural girts secured to vertical, structural columns;
• B. liner panels extending between each three girts with vertically adjacent panels terminating at end girts of the three in slightly spaced relationship;
• C. a plurality of spaced, horizontal subgirts secured to the liner panels with certain of the subgirts positioned on either side of the end girts;
• D. exterior panels extending between each of said three girts and connected to the subgirts with vertically adjacent panels overlapping in unattached relationship;
• E. a clip having angular flanges and secured to said end girts between the adjacent spaced liner panels, the flanges of said clip pinching the adjacent liner panels against the end girts;
• F. means to attach the liner panels to a middle girt of the three girts;
• whereby an external force of predetermined magnitude against the wall panel construction causes the adjacent liner panels to deform about the middle girt as the liner panels pivot about and release from the clip flanges while simultaneously the overlapping, exterior panels pivot and release at their overlapping ends.
