Pressure Coeficients
Design calculations have also included site topography and structural importance when factoring wind pressures on a concrete fence structure. The table shown here provides the AB Pressure Coefficients. The coefficients are listed by the exposure category, but are based on general site topography, structure height and structural importance as well.
| AB Pressure Coefficients (Ce) | ||
| Exposure | H<12 ft (3.7m) Pressure Coefficient |
H>12 ft (3.7m) Pressure Coefficient |
| B | 0.68 | 0.85 |
| C | 0.9 | 1.2 |
| D | 1.2 | 1.5 |
