Cylic loading p-y curve

WebApr 1, 2024 · Offshore pile foundations typically need to be designed for cyclic lateral loading. As per state-of-practice, this is commonly performed by carrying out beam-column analyses where the soil pile interaction is represented by series of p-y springs (curves) along the depth of the pile. WebJan 18, 2024 · Such improved cyclic \(p-y\) curves have for instant recently been presented in , where the reduction in the soil reaction with ongoing cyclic loading has been incorporated using cyclic strain contour diagrams obtained from direct simple shear tests (see ). An extension of the \(p-y\) curves considering rate effects has been presented in .
