The type of pile-to-cap connection in pile foundations is a subject that is always discussed in geotechnical engineering. In this paper, the comparison between two hinged and fixed pile to cap connection types has been accomplished and the earthquake response of the pile group has been measured with shear and axial forces, vertical and horizontal displacement and bending moment through the length of the pile. Therefore a dynamic 3D analysis under earthquake load was used in finite element software ANSYS and the results were compared. Finally, comparisons show that hinged connection minimizes vertical displacement and fixed connection minimizes shear and axial forces and bending moment.
