The basic wind pressure equation is F = 1/2 * rho * U^2 * area * Cd
where U is the wind velocity, rho is the density, area is the appropriate
area (usually cross section) and Cd is the coefficient of drag, which is
shape dependent.
If your library has it, Applied Fluid Dynamics Handbook by Robert D.
Blevins (ISBN 0894647172), has a whole chapter on architectural wind
effects. (the latest versions are published by Krieger, in Malabar, FL.
