soil contact

In this paper, three-dimensional finite element models are set up for structures with different consolidated bases with ANSYS software. Contact elements are created at the contact surface between the soil and foundation. The dynamic behavior and Seismic nonlinear responses of the differently based buildings are analyzed.
