Loads - Area Loads
Area Loads are loads that are spread out over the surface of a slab or a portion of a slab. RISAFoundation allows area loads to be oriented along a vertical axis perpendicular to the XZ plane, with positive loads acting downward and negative loads acting upward. Loads may be input manually in the spreadsheets or drawn graphically in a model view. The area loads can be uniform or tapered.

When you open this spreadsheet, you can view only one load category at a time. Use the drop-down list on the toolbar to specify a different load category.
The first column contains the label for the area load. The second column defines the magnitude of the load. The third column is used to define the peak magnitude of the area load when a tapered area load has been drawn.
