While going through the ASCE 7-16, I encountered with the equation C26.11-8 under chapter 26 'Wind loads: General Requirements'.
fn1=150/h (ft) ------------- Equation (C26.11-8)
There is a reference to two papers by Zhou and Kareem. However, I couldn't quite grasp the idea on how the equation was derived and wanted to know if that equation is reliable to use?
Thank you so much for your time.
All such equations are based on empirical hypothesis and correlation between experimental and actual measurements basis. There is no mathematical derivation in such type of equations.
The first author paper is also available on ResearchGate.
Este tipo de ecuaciones te sirven para análisis preliminares mas no definitivos. Te recomiendo ver a detalle los parámetros sensibles de tu análisis y emplear diversas ecuaciones de la literatura que te permitan ver la variación de los resultados de acuerdo a tus datos sensibles de entrada.
This is an empirical equation, there is no derivation.
It is usually used by designers to estimate the wind load.
