ISFOG 2020 Webinar: New proposed ISO/API p-y curves for piles in clays

Описание: The organizing committee of the 4th ISFOG will propose a series of six webinars on topics of relevance to the offshore geotechnical engineering community. These webinars will emphasize theoretical engineering aspects and will be offered free-of-charge monthly from January 2022 to June 2022. They will consist of 45-min live online presentations, followed by 15 min Q&A.

Organized by Philippe Jeanjean, Senior Advisor, Geotechnics, BP America

The International Organization for Standardization, ISO, will soon update its recommendation ISO 19901-4 Petroleum and natural gas industries — Specific requirements for offshore structures — Part 4: Geotechnical design consideration. One of the important changes relates to the analysis of laterally loaded piles in clays and the generation of the lateral soil springs, the so-called p-y curves.
The current ISO/API recommendations include the long-standing curves recommended by Matlock in 1970 and introduced in the API RP2A code in 1972 for monotonic and cyclic load conditions. The new ISO framework updates and replaces these monotonic and cyclic curves and adds recommendations for an additional limit state: the fatigue limit state. Generally speaking, these new curves provide increased strength and stiffness, as compared to existing recommendations.
The webinar will present these new curves, as codified in the upcoming ISO standard, and the philosophy and thought process behind their development. The talk will also address their intended use and limitations.

The International Symposium on Frontiers in Offshore Geotechnics will be held Aug 28-31, 2022, in Austin, TX. For more information, visit http://www.isfog2020.org.
