Seismic behaviour of shallow foundations on layered liquefiable soils
… as one of the most damaging<br/>natural hazards. Seismic soil liquefaction is often one of the major sources of<br/>damage and disruptions, and has been observed to severely affect key lifelines.<br/>Settlement and tilting of shallow foundations resting on saturated sandy/silty<br/>soils has been …

Seismic Behaviour of Grouted Connections in Precast Concrete Panels
… Canterbury (New Zealand) earthquakes the seismic design of buildings with precast concrete panels has received significant attention. Although this form of construction generally performed adequately in Christchurch, there were a considerable number of precast concrete panel connection …

Seismic behaviour of structures with basements in liquefiable soil
… problems, is not understood. In this thesis, the seismic behaviour of structures with basements in liquefiable soil has been investigated. A series of highly instrumented dynamic centrifuge tests showed that the presence of a basement can reduce the liquefaction induced settlement of a structure …

Seismic behaviour of anchored steel sheet pile walls in sand
… Many coastal areas in the world are highly seismic regions, meaning that ASSP walls are likely to experience earthquakes during their lifespan. ASSP retaining walls are frequently designed for seismic actions using pseudo-static methods. Their displacements can be estimated using a Newmark's …

IMPACT OF SOIL-STRUCTURE INTERACTION ON SEISMIC BEHAVIOUR OF INTEGRAL ABUTMENT BRIDGES
… events cannot be predicted, understanding the behaviour of infrastructure, such as integral bridges, during seismic loading will allow bridge and geotechnical engineers to design these bridges to operate safely during and after earthquake loading and, therefore, reduce the risk of loss of lives …

A study of the seismic behaviour of geomorphological features using ambient noise measurements
… measurements, insight into the dynamic behaviour of an area of coastal instability, characterized by lateral spreading, rock sliding and rockfalls. The characteristic lithology of the area, i.e. a layer of compact Coralline Limestone overlying a layer of clays, gives rise to a ubiquitous …

Assessment of Seismic Behaviour of Large LNG Tanks Considering Soil-Foundation- Structure Interaction
… rapidly, and many LNG tanks are constructed in seismically active coastal regions; hence, potential damage or leakage due to cracking triggered by an earthquake can result in destructive environmental and safety issues. These LNG tanks are usually built near the seashore to reduce the cost and …
