Wind Load Design Procedure
Shearwalls provides a choice of methods for the generation of main wind force resisting system (MWFRS) loads on walls and roofs:
ASCE 7-16 Envelope (Low-rise) method
This method uses the combined external pressure coefficient and gust effect factor GCp from ASCE 7-16 Figure 28.3-1. If you choose this method and your building does not meet the limitations in ASCE 7 30.3 and 26.2, you will be warned upon load generation. Refer to ASCE 7 Envelope (Low-rise) Procedure for more details.
ASCE 7-16 Directional (All heights) method
This method implements load cases 1 and 2 from ASCE 7-16 Figure 27.3-8 and uses external pressure coefficients Cp from Figure 27.3-1. The gust effect factor G is taken from Section 26.11. Refer to ASCE 7 Directional (All heights) Procedure for more details.
For both these procedures, ASCE 7 Table 26.13-1 is used for internal pressure co-efficients, and Figure 30.3-1 for component and cladding loads on walls.
