Structural Considerations
Foundations carry their own weight and the #loads transferred to them from the #superstructures they support to the ground. Vertical loads include the weight of the superstructure itself (dead load) and that of its occupants and contents (live load) in combination with the roof snow load. #Wind and #earthquake loads must also be resisted by the #foundation.
Where foundations extend into the ground and enclose space such as #basements and crawl spaces, they must also adequately resist lateral #soil and #water pressures acting against them. Foundations should not #settle significantly or unevenly over time. They should remain unaffected by the #freezing and #thawing of soils, and #moisture expansion and contraction in the soil.
