This paper presents a discussion on the experimental results of the compression tests performed on full-scale fire-exposed, Reinforced Concrete-Filled Steel Tubes (RCFST) and Reinforced Concrete (RC) short columns (outer diameter 457 mm and length 1600 mm). In the companion papers, full details about the test procedure, thermal field, load-displacement curves are provided. In particular, the domain of research work includes the results of five tests for thermal field measurements, that consider four specimens heated in a gas furnace in standard fire conditions (ISO 834), one specimen heated in an electric furnace in non-standard conditions and the results of six axial compressive tests. In this paper, the results of residual compression tests are discussed and an analytical-experimental comparison is proposed. The work concludes with main remarks about the experimental results.
