Active P-Y Curves for Rigid Walls Supporting Granular Soil Open
In the performance-based design of structures with basement floors, there is interest in quantifying the relationship between the lateral earth pressure and the wall displacement using p-y curves. This paper focuses on studying the develop…

Drained Clay-Pipe Interface Resistance at Low Normal Stresses and Elevated Temperatures Open
Offshore pipelines that transport hydrocarbons under high pressure and high temperature are usually thermally insulated to maintain an elevated temperature and prevent any heat loss to the surroundings. However, the temperatures at the out…

Drained Axial Pipe-Soil Resistance at Low Confinement Using Tilt Table and Direct Shear Tests Open
Establishing a reliable value for the axial pipe-soil interface resistance is critical for the design of offshore pipelines. Over the last few years, several independent research groups have modified existing methodologies or devised new t…

Geotechnical uncertainty, modeling, and decision making Open
Modeling only constitutes one aspect of decision making. The prevailing limitation of applying modeling to practice is the absence of explicit consideration of uncertainties. This review paper covers uncertainty quantification (soil proper…

Effect of compaction method on the undrained strength of fiber-reinforced clay Open
The use of discrete fibers in reinforcing soils is of interest to the geotechnical engineering community. Two limitations exist in experimental studies involving fiber-reinforced clays. First, fiber-reinforced clay specimens are generally …
