Web15 dec. 2016 · The shear strength of a rock joint, or discontinuity, is typically measured using a direct shear test where a load is applied initially, normally to the joint, before this later is sheared. During the test, the tangential force, t, recorded, to displace one part of the joint is recorded together with the actual displacement w. Web16 dec. 2024 · The strength of a structure is defined as that load which effects a destruction of the structure. Destruction occurs if the tensile, compressive, or shear stress in any one component of the structure exceeds its ultimate value, and the structure (or a part of it) is torn, fractured, or irreversibly deformed.

A refinement of the critical state concept is the steady state concept. The steady state strength is defined as the shear strength of the soil when it is at the steady state condition. The steady state condition is defined (Poulos 1981) as "that state in which the mass is continuously deforming at constant volume, constant normal effective stress, constant shear stress, and constant velocity."
