The vertical and rocking impedances of a rigid foundation resting on a semi-infinite transversely isotropic medium are obtained in the frequency domain. In the present approach, the contact pressure distribution on the soil foundation-interface is approximated by a linear combination of known pressure patterns. It is shown herein that the approximate solutions of spatial displacement distributi...

Accurately assessing the forces and reactions on cylindrical objects partially embedded in soils is fundamental in pipeline engineering as well as the analysis and design of off-road vehicles. With a view towards understanding the limiting forces acting over the contact area between the cylinder and the soil, this paper compares two different theoretical approaches for predicting ultimate loads...

this paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. to this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. the g...

A key consideration in physical modeling of seismic problems geotechnical engineering is the impact model container boundaries on soil layer response. The may alter stress-strain behavior from free-field conditions through possible reflection incident shear waves and generation P-waves within layers. In this study, 1-g shaking table experiments were performed to evaluate impacts boundary respon...

In shallow foundations, the third bearing capacity factor, N, has been found to show a decreasing tendency with increasing the foundation size. It is supported by experimental observations and related mainly to stress level dependent nature of the soil. On the other hand, the bearing capacity is often obtained theoretically without consideration of the foundation vertical displacements. In thi...
