Characteristic values — Minimising Energy in Construction

The characteristic value of a material property is normally defined as the value below which not more than 5% of test results may be expected to fall. In our sample of 1000 concrete cubes, this would mean approximately 950 of the samples would be stronger than the characteristic value of the material strength. This is shown in the image below:

Bearing capacity

The allowable bearing capacity is normally calculated from the ultimate bearing capacity using a factor of safety (F s ). When excavating for a foundation, the stress at founding level is relieved by the removal of the weight of soil. The net bearing pressure (q n ) is the increase in stress on the soil. q n = q - q o.
