Soil bearing pressure table

Webable bearing pressure. A square base of 2 m × 2 m is initially assumed. From Fig. N.1, the allowable bearing pressure is n a = 280 kN. This gives a capacity of P a = n a BL = 280 × 2.0 × 2.0 = 1120 kN 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.

WebSoil precompression stress and the compression index are useful indicators to apprise, respectively, soil load bearing capacity and susceptibility to compaction [12,13]. When pressure applied to the soil is lower than the precompression stress, elastic (recoverable) deformation occurs in the soil, and physical properties undergo minor changes.

If P/A exceeds M/S, then the maximum bearing pressure equals P/A + M/S and the minimum bearing pressure equals P/A-M/S. 6. If P/A is less than M/S, then the soil bearing pressure is as shown in Fig. 5-1. Such a soil bearing pressure distribution would normally be considered undesirable because it makes the footing structurally ineffective.
