Cylic loading p-y curve
WebThe cyclic p – y curve, which properly takes into account this effect, was developed as a hyperbolic function. Pseudo-static analysis was also conducted with the proposed cyclic p – y curve, which showed that it was able to properly simulate cyclic laterally loaded pile behavior in sandy soil. KEYWORDS: Cyclic lateral load initial soil stiffness Webthe p‐y curve represents the soil response to the lateral pile deflection because most of the commonly used p‐y curve criteria are based on a very limited number of tests. The p‐y curve recommended by API (American Petroleum Institute) code which is widely used by geotechnical engineers for the
