Soil-structure focus for Rankine events

Delivery of the British Geotechnical Association’s 58th Rankine Lecture by Arup’s Nick O’Riordan in March will be preceded by a free half day seminar

Geotechnical engineers from all over the UK will gather at Imperial College on 21 March this year to hear Arup fellow Nick O’Riordan deliver the 58th Rankine Lecture on the topic of Dynamic soil-structure interaction.

The lecture will examine soil-structure interaction under catastrophic collapse, wave loading, high speed trains and dense urban seismic loading using examples drawn from real-world installations. It will show how economy in design can be driven using unified soil-structure interaction modelling through advanced numerical analysis in which rate effects are explicitly considered.

Recent improvements in the visualisation of foundation behaviour under extreme events enables us to articulate more effectively extreme event scenarios across disciplines and project stakeholders. The lecture will provide a springboard from which resilient, performance-based design methods can be developed and improved, with the promise of feedback from digital data analytics.

Further details about O’Riordan’s career and how this shaped the topic for his Rankine Lecture can be found in GE’s interview with him.

The lecture in the Great Hall of the Sherfield Building will start at 5.30pm and is free to attend. The event will be followed by the Rankine Dinner, which is now sold out.

Rankine Lecture attendees are also invited to join a free event at the same venue in the afternoon before the lecture to learn more about recent advancements in linking fabric, structure and soil behaviour.

The event will be chaired by Imperial College professor of computational geomechanics Lidija Zdravkovic and be split into two sessions with the first focusing on fabric at micro and macro scales and the second on structure and soil behaviour.

In the fabric focused session, Imperial College professor of particulate soil mechanics Catherine O’Sullivan will discuss quantifying fabric and considering its effects; Imperial College senior lecturer in experimental geotechnical engineering Antonio Carraro will look at fabric sensitive soil mechanics; and Université Grenoble Alpes professor Cino Viggiani will look at how well we measure the evolution of sand micro-structure.

After a refreshment break, the structure and soil behaviour session will be opened by xxxx professor King Abdullah University of Science and Technology professor of civil engineering (geotechnical and environmental engineering) at J Carlos Santamarina who will discuss soil structure enduring memory. The session will also include a presentation from University College London professor of geotechnics Matthew Coop on structure in soils of different geological origins and be concluded by GCG senior partner Chris Menkiti who will discuss soil structure evolution and contribution in the context of bulk cargo shipping.

The half day event will start at 1pm and conclude at 4.30pm.
