Abstract

This paper presents results from a four-year research programme. The activities range from basic materials research to analysis and instrumentation of real concrete structures. The analytical part of the project, based on further development and application of the program system DIANA, is briefly described. Experimental results on mechanical properties for concrete subjected to various temperature histories, are compared to material models. Results from a "shrinkage rig", able to measure both thermal dilatation and autogenous shrinkage, are reported. Furthermore, results from the "temperature-stress-testing-machine" are presented, and compared to calculation based on the materials models implemented in the DIANA program. Analysis of a typical structural example is included.
