This dataset presents extensive experimental data available in the literature for concrete-filled tubes (CFT) and ductile concrete-filled double-skin tubes (CFDST) exposed to fire. Different concrete grades, including normal strength (NS), high strength (HS), and ultra-high-strength (UHS) concrete, were tested, and the temperature developments within various cross-sections are provided in the supplementary data. The density, specific heat, and conductivity that are temperature-dependent, are documented by different researchers and current specifications. The preferred models are provided for carbon-steel, stainless-steel, and different grades of concrete. Numerical studies such as those conducted by the authors in a companion paper would find value in this data for validation and verification purposes
