The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Ultimate bearing capacity is the theoretical maximum pressure which can be supported without failure; allowable bearing capacity is the ultimate bearing capacity divided by a factor of ...

The ultimate compressive strength of a material is the maximum uniaxial ... This changes the specimen's geometry and affects its load-bearing capacity, leading to a ...
Strength depends upon material properties. The strength of a material depends on its capacity to withstand axial stress, shear stress, bending, and torsion.The strength of a material is measured in force per unit area (newtons per square millimetre or N/mm², or the equivalent megapascals or MPa in the SI system and often pounds per square inch psi in the United States Customary Units system).
Allowable bearing stress is the bearing capacity divided by a factor of safety. Sometimes, on soft soil sites, large settlements may occur under loaded foundations without actual shear failure occurring; in such cases, the allowable bearing stress is determined with regard to the maximum allowable settlement.
Ultimate strength is an attribute related to a material, rather than just a specific specimen made of the material, and as such it is quoted as the force per unit of cross section area (N/m 2). The ultimate strength is the maximum stress that a material can withstand before it breaks or weakens. [ 12 ]
Good ground is defined as soil that has an ultimate bearing capacity of 300 kilopascals (6,300 lb/sq ft). Soils such as sand, peat and expansive clay, and areas subject to subsidence or liquefaction are not considered good ground under the standard. [7]
Q dy = ultimate dynamic bearing capacity of driven pile; α = pile driving hammer efficiency; W H = weight of hammer; H = hammer drop; S = inelastic set of piles, in distance pr. hammer blow; S e = elastic set of piles, in distance pr. hammer blow; L = pile length; A = pile end area; E = modulus of elasticity of pile material
