Numerical Study on Fire Resistance of Square UHPC Filled Steel Tubular Slender Columns Under Axial Compression
The mechanical response mechanisms of square ultra high performance concrete filled steel tubular (UHPCFST) columns under elevated temperatures differ significantly from those of conventional concrete filled steel tubular (CFST) columns; however, related investigations remain scarce. In this study, a validated thermo-m...
