This paper reviews the phenomena of concrete behavior which is captured in the material data of the Eurocode and reviews additional phenomena which may be included to improve results incertain cases. As a case study, a series of tests which were conducted by Anderberg and Thelandersson in the 1970's in Sweden on concrete samples are studied using first of all the temperature dependent material model which is used in the Eurocodes. The impact of load induced thermal strain is discussed through comparison of the implicit model which is used in the Eurocode and a simple explicit model based on the test results.
