COLLAPSE LOAD COMPUTATION FOR HIGH-FRICTION SOIL

The influence of non-associated flow rule and size of the finite eleme nt model on the collapse load of a strip footing resting on high-frict ion soil is studied. The soil is assumed to be a linearly elastic-perf ectly plastic Mohr-Coulomb material. The dilatancy angle and the model size considered in the analysis have a significant influence on the l oad-deformation behaviour and collapse load. Any attempt to compare th e computed value for a non-associative flow with the analytical soluti on which is generally based on the associated flow rule is questionabl e.
