Postfire Behavior of Circular Concrete-Filled Steel Tubular Columns with Granulated Blast Furnace Slag as Fine Aggregate in Core Concrete
Abstract
AbstractThis study explores the axial compression behavior of concrete-filled steel tube (CFST)
and concrete-filled double-skin steel tube (CFDST) columns made with granulated blast
furnace slag (GBS) as a fine aggregate following exposure to elevated ...
