ABSTRACT

Large centrifuge, radius 5.5 m, payload mass 2000 kg. Has associated digital image processing for flow velocity measurement Comments: Has existing links in France and contacts with other centrifuge groups (e.g. Copenhagen, Cambridge, Bochum, Delft)

Centrifuge testing under dynamic and seismic loadings Comments: Also interested in materials testing and has a proposed collaboration with Prof. J. Schwedes at Braunschweig and Dr Jin Ooi at Edinburgh

CTICM. Large-scale testing facility at Chartres. Fullscale tests. 4 silos in total. Steel structures research programme Comments: Some results have been published (Construction Metallique) but if I understood correctly, the work was industry funded and the publication and sharing of results was restricted. This may now be less of a restriction. Has some proposed/agreed collaborations
