ISFOG Pre-Symposium Workshop: Fundamentals of Cyclic Loading - FREE

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. They will be recorded and posted on YouTube. The February 2022 event will feature Mike Rattley of Geowynd Limited and Carl Erbrich of Fugro talking about the fundamentals of cyclic loading.

This webinar will focus on two central considerations:

Soils respond to cyclic loading:
The cyclic loading response of real soils in the offshore environment will be presented, focusing on the undrained condition, and using examples from tests performed on offshore soil samples. The discussion will highlight several key behavioural aspects which influence idealisations for foundation analysis: cyclic stress-strain response, pore pressure accumulation, and post-cyclic behaviour. The talk will also address the importance of considering the design application during test specification to ensure production of a fit for purpose site-specific laboratory dataset.

Impact of soil response on foundation behavior:
The incorporation of site-specific cyclic soil properties into the design process for offshore foundations will be presented. The benefits of appropriate site-specific cyclic design rather than defaulting to standard design methods that exclude or minimise cyclic effects will be presented. Performance-based approaches that focus on foundation displacement rather than ‘capacities’ will be presented. These points will be highlighted through several examples including storm loading of laterally loaded piles and seismic loading of shallow foundations.
