Monotonic loading of circular surface footings on clay

Abstract

Appropriate modeling of offshore foundations under monotonic loading is a significant challenge in geotechnical engineering. This paper reports experimental and numerical analyses, specifically investigating the response of circular surface footings during monotonic loading and elastoplastic behavior during reloading. By using the findings presented in this paper, it is possible to extend the model to simulate the vertical-load displacement response of offshore bucket foundations.

Vertical Capacity of Bucket Foundations in Undrained Soil

“…The bucket foundations were loaded at the same strain rate as had been used in tests of circular surface foundations (Ibsen, Barari 2011), corresponding to a penetration rate of 44 mm/h for the 20 cm buckets and 60 mm/h for the 30 cm buckets. The mechanical properties required for the numerical simulations were obtained from the tests.…”
