<p>The paper introduces a novel approach for modeling nonlinear hysteretic behavior of reinforced concrete structures in the complex frequency domain. The new approach can be used to perform fast and accurate nonlinear SSI analyses, including sophisticated ...

<p>The object of the paper is the influence of the soil-structure interaction on the dynamic response of masonry towers, for which a high level of stress is involved already in the static field. The relevant deformations and displacements at the base of the ...

This paper presents a study of the dynamic analysis of a building before and after devastating earthquakes using system identification. The eight storey reinforced concrete building is instrumented with 10 accelerometers. The time domain N4SID system identification ...

Aftershocks following an earthquake can be damaging to the built environment, as observed in New Zealand during 2010 and 2011. In this paper, the aftershock sequence is discussed and a soil-foundation-structure numerical model is introduced. The numerical ...

<p>The present paper deals with the influence of soil non-linearity, on the soil-foundation-structure interaction phenomena. Numerical simulations are carried out so as to reveal the beneficial or unfavourable effects of the non-linear SSI on the assessing ...

<p>A great deal of attention has been devoted to the risk connected with construction design during the last period. The design principle connected with potential risks was also included in Eurocode 7 &ndash; Geotechnical Design. At the same time, we very ...

This research involves shake table testing of 1g scale models that mimic the coupled seismic response of a structure on a shallow mat foundation and the foundation soil (termed soil-foundation-structure-interaction or SFSI).

The convergence-confinement method (CCM) for simulating NATM tunnels using plane strain finite element method was in the paper evaluated by comparison with fully 3D simulations. Three real shallow tunnels in urban environment in different stiff clays were ...

<p>Deep excavations frequently cause problems, and sometimes trigger catastrophic collapses, especially in soft clay. In principle, these problems are well understood, but designers may fall between the two stools of naive empiricism and overelaborate finite ...

<p>The Tugun Bypass Tunnel in Gold Coast, Australia was constructed using diaphragm walls with the top-down cut-and-cover method to allow simultaneous construction of an airport runway extension above the tunnel, whilst excavation of the tunnel continued underneath. ...
