The numerical prediction of vibration in buildings due to underground railways involves modelling many physical phenomena. Not least these is the dynamic soil-structure interaction that exists between various elements system. majority existing models assume railway tunnel and building’s foundation negligible, with two sub-systems behaving as though they are uncoupled. This paper presents some i...

Using the Reciprocal Theorem and the principle of superposition, this dissertation examines three procedures for obtaining the impedance functions and driving force vectors necessary for a soil-structure interaction analysis. The first procedure employs a volume integral of body forces and the displacement Green’s Functions to obtain the frequency dependent force-displacement relationship (impe...

the asymmetric problem of rocking rotation of a circular rigid disk embedded in a finite depth of a transversely isotropic half-space is analytically addressed. the rigid disk is assumed to be in frictionless contact with the elastic half-space. by virtue of appropriate green's functions, the mixed boundary value problem is written as a dual integral equation. employing further mathematica...

Earthquake-induced soil liquefaction can generate excessive damage to building structures due significant reduction in effective stress. With increasing urbanisation and population growth, the performance of closely spaced buildings, such as those towns cities, is greater concern where structure–soil–structure interaction (SSSI) may occur conjunction with full or partial liquefaction. This stud...

In this paper effect of pile-soil consideration in obtaining seismic response offshore structure is assessed due to earthquake loading. InducedSeismic force is one of the most important excitations for the dynamic response of an offshore structure. According to API, Seismic forces should be accounted in platform design for seismically active regions in order to determine the allowable seismic r...

Through conducting a comparative experimental study of small-aspect-ratio isolated structure models on multi-layered soft soil foundations and rigid foundations, this paper investigates the influence soil–structure interaction (SSI) effects seismic response structures foundations. An energy balance equation for systems considering SSI is proposed, impact dissipation analyzed in depth. The analy...

The aim of the present paper is to evaluate the influence of the Soil- Foundation- Structure Interaction (SFSI) effects on the component demand modifier factor of concrete gravity beams based on ASCE 41-06 standard. To this end, the beam on the nonlinear Winkler foundation approach is employed which is a simple and efficient method. At first, four sets of 3-, 6-, 10- and 15-storey concrete mome...
