Floor loading calculation uk.

2attic loads may be included in the floor live load but a 10 psf attic load is typically used only to size ceiling joists adequately for access purposes. Load types loads used in design load equations are given letters by type. Used but they typically defined the load cases or combination stress or strength limits and deflection limits. Click on a span to generate a full calculation you can adjust the exact span.

However if the attic is intended for storage the attic live load or some portion should also be considered for the design of other elements in the load path. D dead load l live load l r live roof load w wind load s snow load e earthquake load r rainwater load or ice water load.
