Modelling of Strip Foundations for Serviceability Assessment

A series of experiments has been carried out in a purpose-built sand tank to assess the foundation/sand behaviour under load where the investigation is confined to the non-failure characteristics of the soil. The semi-full-scale foundation is of bolted steel box construction, instrumented to provide the contact stresses at selected points. Stresses and displacements are also measured automatically at various depths in the sand, using a dedicated computer system with a specially developed management suite of programs. The variation of displacements and stresses, once processed, are plotted against depth. The results are then compared with data from linear finite element method, using back-analysis techniques. Various parameters are then established and ascertained. R. Delpak, G.O. Rowlands and A. Siraty
