Cylic loading p-y curve
WebApr 1, 2024 · To generate the cyclic p c − y curve, the backbone curve is first generated by applying static lateral loads to the pile, which is just the static p c − y curve. In this study, the backbone curve is derived based on the nonlinear SWM at each depth. http://www.findapile.com/p-y-curves/definition

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 . WebTraditionally, the p-y curves are formulated in terms of non-linear (elastic) relations between the lateral movement y and the soil response pressure p in terms of monotonic loading (until failure). These curves were established by back-analysis of a series of tests carried out in the 1950es by Matlock and co-workers. The tests were primarily ...
