Parameter identification for coupled elasto-plasto-damage model for overheated concrete

The methodology of experimental acquisition and subsequent processing of data for identification of nonlinear elasto-plasto-damage concrete model parameters are considered. Typical measurement equipment and data acquisition process are described. The experiments were carried out on standard specimens of cubic and prismatic form under compression and dog-bone-shaped specimens under tension. Elasticity modulus in tension and compression, ultimate strengths in compression and tension, damage evolutions during deformations process and other mechanical characteristics were obtained. The results of parameter identification and validation for typical structural concrete including regular and overheated concrete are presented and discussed
