LimitState Customer Presentation at ISFOG 2010
LimitState customer Fugro S.A./N.V. will be presenting a paper on 'Simplified VH equations for foundation punch-through sand into clay' at the ISFOG 2010 conference (2nd International Symposium on Frontiers in Offshore Geotechnics), to be held 8-10 November 2010 in Perth, Australia.
The paper describes the use of LimitState:GEO to calibrate an in-house software tool, the authors observing that
results converged steadily towards analytical solutions by increasing the density of nodes. Solutions within 10% tolerance could generally be obtained within a few minutes compared to several hours with Plaxis. Therefore, LimitState:GEO was found to be the most appropriate tool for our ultimate load problem.
The authors conclude that LimitState:GEO is
fast and reliable and permitted about 800 analyses in a rigorous and consistent manner.
The paper will be presented at 12:00 on Wednesday 10th November 2010. Further details of the paper are provided below.
TITLE: Simplified VH equations for foundation punch-through sand into clay
AUTHORS: J.-C. Ballard, P. Delvosal and P.H. Yonatan, Fugro Engineers S.A. / N.V., Brussels, Belgium, A. Holeyman, Université Catholique de Louvain, Belgium, S. Kay, Fugro Engineers B.V., Leidschendam, Netherlands
ABSTRACT: This paper gives simplified VH equations for surface strip foundation punch-through sand into
uniform clay derived from 2D plane strain numerical simulations using Limitstate:GEO. The equations have
been calibrated in the engineering ranges normally encountered in geotechnical engineering practice and have
been inserted into proprietary computer program ISOBARE for everyday use. The method is currently being
calibrated for other foundation shapes (circles and rectangles) and for clay with undrained shear strength linearly
increasing with depth.
