BRITISH GEOTECHNICAL ASSOCIATION AND GEOTECHNIQUE LECTURE
to be held on Wednesday 12 September 2001 at 5.30 pm at The
Institution of Civil Engineers
FOUNDATIONS ON SAND: TOWARDS A MORE SECURE BASIS FOR DESIGN
Presented by
PROFESSOR GUY HOULSBY
University of Oxford
and
PROFESSOR ROY BUTTERFIELD
University of Southampton
The conventional analysis of shallow foundations under combined
loading uses inclination and eccentricity factors, but there are sound
reasons for preferring an approach based directly on the use of the
loading vector (V,M,H). By incorporating also the corresponding
displacement vector, foundation displacements as well as load capacity
can be addressed.
The lecture explores such an approach in relation to shallow, rigid
foundations on sand. Relevant dimensionless quantities are
established and the concepts of interaction diagrams in load space are
introduced. These are readily extended to a rigorous work-hardening
plasticity model of the problem.
The theoretical model is supported by high quality experimental data,
including tests specifically designed to explore the shape of the
yield surface for the footings. The resulting approach has much in
common with Critical State Soil Mechanics, and these analogies will be
explored.
The ideas are relevant to all areas where foundations are subjected to
lateral and moment loading, for instance retaining structures,
offshore platforms and in earthquake engineering.
There is no charge to attend and all are welcome.
Tea and Biscuits are served from 5.00 pm.
