Laboratory Model Test and Numerical Analysis of Bearing Capacity of Rigid Strip Footing

抄録

This paper reports the results of laboratory model tests subjected to bearing capacity of rigid strip footing. Based on the results, this paper proposes a numerical procedure for estimating the bearing capacity of rigid strip footing under some complex conditions. The procedure uses a smeared shear band approach and a modified initial stress method to provide an explicit collapse mechanism represented by the stress yield condition, assuming the Mohr-Coulomb yield criterion with a simple non-associated flow rule. The procedure employs a simple constitutive model which requires a small number of soil parameters, so that it may be applied to practical design work rather than the simulation of actual failure behavior. Comparison is made between the results calculated by the numerical procedures and those of the laboratory model tests.
