A new and efficient method is proposed for investigating the steady-state response of an end bearing pile embedded in a homogeneous and isotropic soil layer and subjected to time-harmonic torsional loads at the pile head. In the model, the soil was assumed to be a linear viscoelastic continuum and the radial and vertical displacements were ignored. The function form of the torsional displacement for the soil–pile system was obtained. The Hamilton’s principle and variational approach were applied to analytically solve the pile and soil displacement equations by using an iterative algorithm. The model was validated by comparing the results of the proposed model with those of previous analytical studies. A parametric study was performed to analyze the effect of the pile slenderness ratio and the pile–soil modulus ratio on the dynamic response of piles under torsional loading.
