Tables 9.6.1.3.-A to 9.6.1.3.-F are based on CAN/CGSB-12.20-M, “Structural Design of Glass for Buildings”, and the wind load provisions in Article 4.1.7.3. The maximum glass area values given in these Tables are intended to be equal to or smaller than those that would be determined using the standard and wind load provisions directly to design for each individual case.
