Abstract

A fully triaxial material model for concrete was implemented in a commercial finite element code. The only required input parameter was the cylinder compressive strength. The material model was suitable for non-linear finite element analyses of large concrete structures. The importance of including a crack closure algorithm was demonstrated on a case involving sequential loading. Bayesian inference was applied to results from a series of benchmark analyses, and the results indicate that the modelling uncertainty can be represented by a log-normal variable with a mean 1.10 and a coefficient of variation of 10.9%.
