Five years back, I developed a Python function to calculate closed form exact values for wind forces and wind CGs.
I use only calculus — no more bar charts with 0′ to 15′, 20′ to 25′, 25′ to 30′, et cetera —- a curve rather than a step function.
The ASCE function for kz is discontinuous at z = 15′:
- when , , a constant
- when ,
