vb = vb,0 * cdir * cseason
For buildings with ( h \leq 15 , m ) and not dynamically sensitive: [ c_s c_d = 1.0 ] Otherwise, use Annex D or simplified method (reduction for higher slenderness). In many Excel tools, allow user input or default to 1.0 for low-rise. I created another Excel formula to calculate vm:
): Accounts for increased wind speeds over hills, cliffs, or ridges. 3. Peak Velocity Pressure (
: Cliffs, hills, and ridges compress air streams, accelerating wind speeds. If your project sits on a slope, ensure your spreadsheet accounts for an orography factor ( ) greater than 1.0.
