Probabilistic Analysis of the Failure Time of Concrete-Filled Steel Tube (CFST) Columns under Post-Blast Fire Loading

This study examines the behavior and resistance of concrete-filled steel tube (CFST) columns under post-blast fire conditions, where prior explosions cause initial structural damage affecting fire performance. A blast equivalent to 20 kg TNT at a 1.5 m distance was simulated, followed by fire exposure. Seven numerical...
