An 'Innovation in Geotechnics' event has been organized by the Institution of Civil Engineers Yorkshire Geotechnical Group, and Drs Gilbert and Smith of LimitState will be making a presentation on 'Advances in Geotechnical Limit Analysis'.

If you wish to register for the seminar, please visit the ICE Yorkshire Group website.

Presentation: 'Advances in geotechnical limit analysis'

Limit analysis has for many decades played an important role in geotechnical engineering practice. To extend the usefulness of traditional hand-based limit analysis methods, a variety of computational limit analysis methods have recently been successfully developed. In particular, the recently developed Discontinuity Layout Optimization (DLO) analysis procedure now provides geotechnical engineers with a very powerful means of assessing the stability of slopes, retaining walls, footings and virtually any other geotechnical feature, including those incorporating soil reinforcement.

In the presentation, details of the DLO procedure will be described and the DLO-based LimitState:GEO software will be applied to various design problems to illustrate how effectively the new tool bridges the gap between existing single application hand-type analysis methods and those based on much more complex incremental analysis methods (e.g. non-linear finite element analysis). The emphasis will be on practical assessment of the Ultimate Limit State (ULS), covering appropriate problem definition for a range of ULS design problems and application in accordance with Eurocode 7.
