How to Calculate Wind Load on a Rectangular Antenna
How to Calculate Wind Load on a Rectangular Antenna
(OP)
I need to calculate the wind-loading force (lbf or N) that will be applied to my rectangular antenna enclosure (face area of 2.6 sq ft /0.24 sq m) in a wind speed of 60mph (97km/h. The estimated drag coefficient (based on a flat face with rounded edges) is 1.9.
Can someone provide me with the correct formula to use, or point me I the direction to solving this?
Thank you,

Fluid mechanics and wind tunnels is one approach. Structural engineers look to ANSI/ASCE 7- latest ed., for wind loads on structures, and it's a real mind bender, but it is the building code for these kinds of things.

ASCE 7-latest edition should walk you through the analytical process to determine an applied force for your structure. I find non-building structures to be easier to analyze and less "mind bending" as dhengr put it. It does take a little guidance to get through all of the variables though the first few times.

anyways, i was wondering if the code defined the wind speed, then the load is 1/2rhoV^2*A, or the pressure, then the load is p*A ...
