When Garage Load is selected in Settings, the program analyzes additional live load cases, applying a single 3000 lb concentrated load per the International Building Code (IBC). The concentrated live load is not applied concurrently with any other live load, and is placed at various locations along the span to induce maximum stresses per the IBC. Cantilever spans are not allowed when Garage Load is selected.
When Garage Load is selected, a note referencing the loading is listed on the design report, along with requirements for garage floor surface and sheathing.
