How to Calculate Wind Directionality Factor given Velocity Pressure?
Wind Directionality Factor given Velocity Pressure calculator uses Wind Directionality Factor = Velocity Pressure/(0.00256*Velocity Exposure Coefficient*Topographic Factor*Importance Factor for End Use*Basic Wind Speed^2) to calculate the Wind Directionality Factor, The Wind Directionality Factor given Velocity Pressure is defined as the load reduction factor intended to take into account the less than 100% probability that the design event wind direction aligns with the worst case building aerodynamics. Wind Directionality Factor is denoted by Kd symbol.
How to calculate Wind Directionality Factor given Velocity Pressure using this online calculator? To use this online calculator for Wind Directionality Factor given Velocity Pressure, enter Velocity Pressure (q), Velocity Exposure Coefficient (Kz), Topographic Factor (Kzt), Importance Factor for End Use (I) & Basic Wind Speed (VB) and hit the calculate button. Here is how the Wind Directionality Factor given Velocity Pressure calculation can be explained with given input values -> 0.387698 = 29.7632788711526/(0.00256*0.85*25*0.8*29.6107^2).
