Nonlinear analysis of concrete structures

Abstract

Solution capabilities for two- and three-dimensional nonlinear finite element analysis of concrete structures are presented. The concrete material is modeled including the triaxial nonlinear stress-strain behavior, tensile cracking, tension-stiffening, compression crushing and strain-softening. The results of various sample analyses are given to demonstrate the constitutive model and the solution strategies. These analyses include the response predictions of a test beam and of small scale models of two reactor vessels.
