RISLateral Undrained Capacity of a Multiline Ring Anchor in Clay
Publisher: ASCE
Abstract: Offshore wind energy is an attractive alternative in pursuing the nation's clean energy goals due to the significant demand for electricity in the coastal areas of the United States. Locating sites further offshore in ...
Experimental and Numerical Investigation of the Performance of Piles and Suction Caissons Subjected to Inclined Cyclic Loading in Cohesive Soils
Publisher: ASCE
Abstract: Cyclic loading on caisson and pile anchors can be a significant design issue, particularly with respect to cumulative vertical displacements that can lead to reduction in embedment depth and load capacity of the anchor. ...
Seafloor-Riser Interaction Model
Publisher: American Society of Civil Engineers
Abstract: Fatigue stresses associated with extreme storms, vessel movements, and vortex-induced vibrations are critical to the performance of steel catenary risers. The critical location for fatigue damage often occurs within the ...
Behavior of Suction Embedded Plate Anchors during Keying Process
Publisher: American Society of Civil Engineers
Abstract: Suction embedded plate anchors (SEPLAs) allow for accurate positioning, thus providing an attractive alternative to traditional drag embedment anchors. This paper presents an analytical model for predicting the behavior ...
Effects of Disturbance on Undrained Strengths Interpreted from Pressuremeter Tests
Publisher: American Society of Civil Engineers
Abstract: Although the cylindrical cavity expansion theory should provide a sound basis for obtaining the undrained shear strength of clays from pressuremeter tests, the interpreted strengths are often inconsistent with data measured ...
Numerical Investigation of the Performance of Caissons in Cohesive Soils under Cyclic Loading
Publisher: ASCE
Abstract: Cumulative plastic deformations under cyclic loading can be a key consideration in the design of caissons and short piles. In the case of caissons and piles serving as anchors for floating offshore structures, the possibility ...
Behavior of Piggy-Backed Drag Embedment Anchors in Marine Soils
Publisher: ASCE
Abstract: This paper summarizes the analytical and experimental results of piggy-backed drag embedment anchors composed of two drag embedment anchors. Drag embedment tests with piggy-backed drag embedment anchors were performed with ...
Comparison of Analytical and Centrifuge Model Tests for Suction Caissons Subjected to Combined Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A plastic limit formulation was previously developed for estimating caisson uplift in cohesive soils under general conditions of vertical, horizontal, and inclined loading. The formulation considers ...
Capacity of Short Piles and Caissons in Soft Clay from Geotechnical Centrifuge Tests
Publisher: American Society of Civil Engineers
Abstract: Geotechnical centrifuge tests were conducted to examine the behavior of low-aspect-ratio piles and caissons in clayey soils subject to high moment loading. Model piles with an aspect ratio of two were tested in the 150g-t ...
