Shear creep behaviour of soil–structure interfaces under thermal cyclic loading

The coupling effect of initial shear stress and thermal cycles on the thermomechanical behaviour clay concrete sand–concrete interfaces has been studied. A set drained monotonic direct tests was conducted at soil–concrete interface level. Samples were initially sheared to half material's strength then they subjected five heating/cooling before being failure. test results showed that materials negligible, yet displacement occurred during application without an increase in stress, confirming between temperature. In addition, a slight stiffness due observed which diminished with further shearing.
