Summary:
The load-bearing performance of concrete structures during or after fire is directly influenced by its
thermal response; i.e. temperature within the depth of concrete element being analyzed. Therefore, a
sound understanding of both: thermal properties and thermal boundary conditions becomes key.
However, the existing diversity, specially of the thermal boundary conditions, can yield significant
disparity in the outputs of thermal analyses.
The scope of the work presented herein studies the sensitivity of the structural fire performance of
concrete structures, analyzing the influence of: (1) material thermal properties and (2) thermal boundary conditions. The subsequent analysis leads to the identification of model properties and conditions having a great or little relevance in the overall outcome of a thermal and mechanical analysis of reinforced concrete structural elements.
