Welcome to our Windload Calculator
These calculations will be carried out in accordance with the requirements of BS EN 1991-1-4:2005 + A1:2010 the UK National Annex to Eurocode 1 Actions on structures Part 1-4:
These calculations are only valid for sites where topography is not significant. As a generalisation any building more than half-way up a hill, or on a ridge or cliff, will have increased wind loading. If your project falls into this category, then a more detailed analysis will be required.
This calculation software does not work with some versions of Microsoft Internet Explorer. For quickest functionality, we suggest Google Chrome. If you do not have Google Chrome installed, you can install it here
