Limit Load Analysis of Thick-Walled Concrete Structures. A Finite Element Approach to Fracture
The interaction of constitutive modeling and finite element solution techniques for limit load prediction of concrete structures is illustrated. On the constitutive side, an engineering model of concrete fracture was developed in which the Mohr-Coulomb criterion is augmented by tension cut-off to describe incipient failure. Upon intersection with the stress path the failure surface collapses for brittle behavior according to one of three softening rules, no-tension, no-cohesion, and no-friction. The stress transfer accompanying the energy dissipation during local failure was modelled by several fracture rules which were examined with regard to ultimate load prediction. On the numerical side the effect of finite element idealization was studied first as far as ultimate load convergence is concerned. Subsequently, incremental tangential and initial load techniques were compared together with the effect of step size. Limit load analyses of a thick-walled concrete ring and a lined concrete reactor closure are given with examples of the engineering praxis. (Author)
