Abstract: This paper presents experimental results of full‐scale fire tests with loading on concrete‐filled steel‐tube (CFST) columns using fire‐resistant (FR) steel for building structural use. By covering the tube surface with ...

Abstract: This paper is to verify the fire resistance of columns made from fire‐resistant (FR) structural steel by means of a full‐scale loaded heat test and numerical analysis. Because of the elements contained, FR steel has higher ...
