This update allows engineers to define effective wind area individually by wind zone, instead of applying a single global value across the entire roof or wall.
When enabled, the calculator automatically applies the correct GCp coefficients (positive and negative) based on the specified effective area for each zone, including interpolation where required by ASCE 7 provisions.
Built-in validation messaging ensures selected wind zones are applicable to the chosen building geometry, improving clarity and reducing input errors.
Supports roof and wall zones for low- to mid-rise buildings under both ASCE 7-16 and ASCE 7-22, fully aligned with C&C methodology requirements.
By allowing zone-specific effective areas within a single model, this enhancement reduces repetitive calculator runs, minimizes manual coefficient selection errors, and streamlines wind design workflows, saving time while improving confidence in code-compliant results.
