Abstract
This paper presents a new mathematical method for analysis of piles under a combination of static and dynamic loads. In this study has been used the SSM (segment by segment method), which is verified using existing numerical and analytical solutions, is more efficient than the equivalent numerical solutions for example finite eminent methods. This method is useable inhomogeniouse soils. The characteristic effects of surrounding soil on the pile response are determined using stiffness and damping parameters of the soil - pile system. These effects can be taken into account if a proper soil reaction is employed. The soil reaction on the pile is represented by springs and dashpots, which are modeled using elasto-dynamic theory or elastic half-space theory. The pile is divided into cylindrical segments connected rigidly at nodes connected by stiff spring, which are characterized using linear elastic theory. Also effective parameters have computed in complex stiffness of the soil - pile system such as pile slenderness ratio, mass ratio, Poisson’s ratio, excitation frequency, wave velocity ratio and pile static load and No separation is allowed in the soil-pile interface.

Response of Piles under a Combination of Axial Static Loads and Lateral Harmonic Vibrations
