On the Torsional Stiffness of Rigid Piers Embedded in Isotropic Elastic Soils


This paper develops an approximate expression for the torsional stiffness of a rigid cylindrical pier embedded in an isotropic elastic soil mass. The approximate solution is derived by considering the torsion of a hemispheroidal rigid inclusion embedded in bonded contact with an clastic medium. The expression for the torsional stiffness of the pier is expressed as a function of its length to diameter aspect ratio.
