Shore Hardness Scale - The Shore Hardness Scale represents the amount of pressure an object or material can endure and the hardness can be defined as the materials resistance to permanent indentation.

Shear Stud - A shear stud is typically a small element welded to a steel construction component designed to resist shear loadings between the concrete and steel interfaces.

Shear Stress - It is very important to know the magnitude of the shear stresses that a concrete slab is subject to, as failure due to shear is often very sudden and catastrophic.

Settlement - is the change in elevation of the surface of the ground caused by deflection of the soil below the slab under load.
