Abstract

  The authors have developed a constitutive model of the three dimensional Rigid-Body-Spring Model with random geometry for quantitative evaluation of the response of concrete subjected to active lateral pressure and uniaxial compression. In the present study, numerical analyses of confined concrete specimens under uniaxil compression using the proposed model were conducted for validation of the applicability to the compressive response subjected to passive lateral pressure. By comparing analytical results with empirical formula or the experimental results, we confirmed that the proposed model can reasonably evaluate the compressive strength, the softening behavior and the localization behavior. In addition, the failure process and the stress transfer mechanism of confined concrete were discussed.
