WebThe p-y analysis is a numerical model that simulates the soil resistance as predefined nonlinear springs, where p is the soil pressure per unit length of the pile and y is the pile deflection. The soil is represented by a series of … 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.
http://www.findapile.com/p-y-curves/definition WebThe p-y curves are strongly responsive to the nature of the loading. Recommendations have been developed for predicting curves for short-term static loading and for cyclic (or repeated) loading. However, there are no current recommendations for the cases where the loading is dynamic or sustained.
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 ...
