Mechanism Of Seismic Liquefaction For Heterogeneous Soil, Radu Popescu, Pradipta Chakrabortty
Architectural Engineering
In addition to inducing uncertainty in the predicted response, natural spatial variability of soil properties affects the mechanical response of geotechnical structures. When a failure surface is involved in the response, this surface can deviate from its theoretical location to pass through weaker zones of material. For the case of seismically induced soil liquefaction, it has been found that a larger amount of excess pore water pressure is generated in a soil exhibiting small-scale variability of its properties than in the corresponding uniform soil having geomechanical properties equal to the average properties of the heterogeneous soil. An explanation for this …

Offshore Anchor Piles Under Mooring Forces: Centrifuge Modeling, Mohamed I. Ramadan, Stephen D. Butt, Radu Popescu
Architectural Engineering
Offshore anchor piles are seafloor moorings that keep the position of floating structures during a harsh environment. These piles are usually subjected to a wide range of monotonic and cyclic lateral-to-oblique pullout forces. Centrifuge tests were carried out to study the behavior of offshore anchor piles under mooring forces in saturated dense sand. The tests were carried out at different loading angles. All piles were jacked into the sand bed in-flight. The pile models were instrumented with strain gauges. Bending moment, soil pressure, and pile lateral deflection profiles are presented and discussed. It was found that there is a significant …
