We are using the "Generate Wind Loads" tool in Robot 2019 to help determine the windward and leeward pressures onto our proposed building, which is a 50m tall tower with shorter building sections, overall approx. 100mm long.
We have built a simple model with panels to represent the elevations of the building, with the Z coordinate "0" being ground level. The site is in London, so basic wind speed of 22m/s.
When we have run the wind load generator, the windward and leeward pressures are less than what we would expect for a building of this height and when compared to pressures determined by hand/other software. For the top of the 50m tower would would anticipate net pressure of approx. 1.3kPa. Robot is determining 0.7kPa.
We wondered whether the Wind Velocity input should be the max. gust wind speed rather than basic wind speed? Or should we adjust the Wind Profile to something other than the automatic setting?
Any advice would be appreciated.
