A numerical model was developed to simulate the response of two instrumented, centrifuge model tests on soft clay and to investigate the factors that affect the seismic ground response. The centrifuge tests simulated the behavior of a rectangular building on 30 m uniform and layered soft soils. Each test model was subjected to several earthquakelike shaking events at a centrifugal acceleration ...

This paper presents new research in the field of nonlinear static seismic analysis and N2 method for soil-structure systems. The rationale this study stems from inclusion systems simplified displacement-based design methods. conducted comprises three parts, including original experimental investigations, development numerical models validation results. A methodology is presented that provides a...

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...
