図4.1.7.6.-B – External peak values of \( C_{p} C_{g} \) on individual walls for the design of cladding and secondary structural members;
図4.1.7.6.-C – External peak values of \( C_{p} C_{g} \) on roofs with a slope of 7° or less for the design of structural components and cladding;
図4.1.7.6.-E – External peak values of \( C_{p} C_{g} \) on single-span gabled and hipped roofs with a slope greater than 7° for the design of structural components and cladding; そして
図4.1.7.6.-G – External peak values of \( C_{p} C_{g} \) on monoslope roofs for the design of structural components and cladding.
The process is done by usingEngauge Digitizer, as the exact values in the graphs are not explicitly shown or stated in the code reference. With this, for transparency, the following data are being used in the Load Generator – NBCCを使用した風荷重計算 2015 そして 2020. The adopted values are rounded to the nearest tenths (higher magnitude). Values in between known points are interpolated linearly using log-scale for the area axis.
