ANALYTICAL SOLUTION FOR TWO-DIMENSIONAL SOIL-STRUCTURE INTERACTION WITH NORMAL PLANE P-WAVE INCIDENCE

In this paper an analytical solution for two dimensional Soil-Structure Interaction (2D SSI) model is presented.The model consists of three parts: stress-free elastic, isotropic, homogeneous ground half-space, idealized rigid semicircular foundation and rectangular homogeneous building.The interactive system is excited by vertical incident P-wave.The presented analytical solution satisfies the stress-free boundary conditions at the half-space surface.The analyzed solutions for foundation motion and the relative response of the building can be further used for verification of numerical models developed for 2D SSI
