Wind Pressure Coefficients: roof_leeward
ASCE 7-22 wind pressure coefficients — external Cp (Figure 27.3-1), internal GCpi (Table 26.13-1), low-rise GCpf (Figure 28.3-1), and gust factor G for MWFRS design of enclosed/partially-enclosed buildings
| surface id | roof slope deg | Cp or GCp max (dimensionless) | Cp or GCp min (dimensionless) | L B ratio | coefficient type | load case | notes | surface category | use with | x h ratio |
|---|---|---|---|---|---|---|---|---|---|---|
