Abstract :
[en] The paper is given of an extended model for concrete in compression at elevated
temperature that incorporates elastic, plastic and creep strain as a function of temperature and
stress history. The mechanical strain calculated as a function of elastic strain, plastic strain and
thermal induced strain. The thermal induced strain is relative independent compared to
dependence of Young’s Modulus by load history. Actually the term comprises elastic, plastic and
(pure) transient creep strains as we will show. A comparison is given between experimental
results with cylindrical specimens and calculated results.
