RISNumerical Analysis of Large-Diameter Monopiles in Dense Sand Supporting Offshore Wind Turbines
Publisher: American Society of Civil Engineers
Abstract: Large-diameter monopiles are widely used foundations for offshore wind turbines. In the present study, three-dimensional finite-element (FE) analyses are performed to estimate the static lateral load-carrying capacity of ...

Viscosity Effects on One-Dimensional Consolidation of Clay
Publisher: American Society of Civil Engineers
Abstract: A constitutive relationship for one-dimensional consolidation of clays is presented. It recognizes the importance of structural viscosity and yielding in controlling many of the phenomena associated with the consolidation ...
Numerical Modeling of Suction and Trench Formation at the Touchdown Zone of Steel Catenary Riser
Publisher: American Society of Civil Engineers
Abstract: . The simulation results for penetration are presented in Hawlader et al. (2014). In this paper, CFD simulations of uplift resistance, suction and trench formation using ANSYS CFX are discussed. A new model for undrained shear strength of soft clay is proposed...
Modeling of Buried Pipelines in Dense Sand for Oblique Movement in Vertical–Lateral Plane
Publisher: ASCE
Abstract: Finite-element modeling of pipelines buried in dense sand under oblique loading in vertical (upward)–lateral load space is presented. The prepeak hardening, postpeak softening, density, and confining pressure–dependent ...
Modeling of Initial Stresses and Seepage for Large Deformation Finite-Element Simulation of Sensitive Clay Landslides
Publisher: ASCE
Abstract: Groundwater seepage and an increased lateral earth pressure coefficient at rest (K0) increase the potential for triggering large-scale landslides in sensitive clays. After the failure is triggered, the successive retrogressive ...
Factors Affecting Frost Heave of Chilled Gas Pipelines
Publisher: ASCE
Abstract: Chilled gas pipelines generally traverse a long distance through various soils and may operate for decades with varying temperatures of gas, surrounding soil, and ground surface. The present study investigates the effects ...
Estimation of Collector Performance Parameters From Daily System Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A test procedure to estimate the daily mean values of the linear collector characteristics, FR ,(τα) and FR UL , from the measured variation of the storage tank temperature was investigated. ...
Penetration of Steel Catenary Riser in Soft Clay Seabed: Finite-Element and Finite-Volume Methods
Publisher: American Society of Civil Engineers
Abstract: The penetration of steel catenary risers and other cylindrical objects, such as offshore pipelines or T-bar penetrometers, in a soft clay seabed is of practical importance in deepwater oil and gas development. Finite-element ...
