A state-of-the-art, three-dimensional, nonlinear finite element algorithm is developed and used to study piling stresses and pile-soil interaction in integral abutment bridges. The finite element idealization consists of beam-column elements with geometric and material nonlinearities for the pile, and nonlinear springs for the soil. An idealized soil model (a modified Ramberg-Osgood cyclic model) was introduced in this investigation to obtain the tangent stiffness of the nonlinear spring… CONTINUE READING
