Генератор нагрузки SkyCiv использует оцифрованные значения следующих цифр при расчете \( C_{п} C_{грамм} \) при расчете расчетного ветрового давления на элементы конструкций и облицовку:
Рисунок 4.1.7.6.-Б – External peak values of \( C_{п} C_{грамм} \) on individual walls for the design of cladding and secondary structural members;
Рисунок 4.1.7.6.-С – External peak values of \( C_{п} C_{грамм} \) on roofs with a slope of 7° or less for the design of structural components and cladding;
Рисунок 4.1.7.6.-E – External peak values of \( C_{п} C_{грамм} \) on single-span gabled and hipped roofs with a slope greater than 7° for the design of structural components and cladding; и
Рисунок 4.1.7.6.-G – External peak values of \( C_{п} C_{грамм} \) 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 – Расчеты ветровой нагрузки с использованием NBCC 2015 и 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.
