Soil bearing pressure psf
WebThe allowable bearing pressure is the soil's ability to carry the load of a building and its contents without excessive settlement. For one and two-storey buildings, the Building Code of Australia (BCA) requires a minimum bearing pressure of only: 100 kPa for under strip and pad footing systems. 50 kPa for under slab footings. Weba. When soil tests are required by Section R401.4, the allowable bearing capacities of the soil shall be part of the recommendations. b. Where the building offi cial determines that in-place soils with an allowable bearing capacity of less than 1,500 psf are likely to be present at the site , the allowable bearing capacity shall be
