Wind Load Calculation As Per Euro Code: Input Details

This document calculates wind load on a circular structure according to Eurocode standards. It provides input parameters such as basic wind velocity, terrain category, and structure dimensions. It then calculates the mean wind velocity, peak velocity pressure, Reynolds number, force coefficient, total wind force, effective wind pressure, and uniformly distributed load on the structure based on the input parameters and standard equations. The total wind force calculated is 17.7344 kN and the effective wind pressure is 2.22 kN/m^2.
