CBS² used the appropriate building code to develop the components & cladding wind pressure for the building along with the allowable deflection limits for the ACM system. Using the Aluminum Design Manual the allowable stress for the ACM was determined and compared to the stress created by the wind loading applied to the ACM face. The center of panel deflection caused by the applied wind load was calculated and compared to the deflection limit set by the building code.

CBS² was responsible for the attachment of the ACM system all the way back to the building structure. The process of transferring the loads from the ACM face to the building structure starts with the perimeter rivets that attaches the ACM panel to the perimeter extrusion. Rivets are checked for shear capacity by calculating the strength of the rivet body along with the bearing capacity of the rivet on the ACM panel, both need to be checked to make sure there is no failure. Continuous perimeters extrusion are analyzed for bending to make sure that they will hold their shape under the applied wind loads. The perimeter extrusion is slid into and secured to the spaced wall clips. Spacing of the wall clips is determined by both the bending strength of the clip and the capacity of the screws used to secure the clip to the sub-framing system. The sub-framing for this project was 16ga bend zee furrings, this allowed for sufficient pullout capacity of the wall clip screws and adequate bending strength of the furring. Finally, the zee furring is attached to the building framing.
