Experimental Study of Post-fire Performance of Ceramsite Concrete Filled Steel Tabular Columns

The post-fire performance of a set of ceramsite concrete filled steel tabular short columns (noted as CCSSC) after exposure to fire are experimentally studied. Effect of the maximum value of fire response temperatures and geometrical parameters of the composite columns on the strength and ductility of the specimens were especially discussed. The test results show that the specimens of CCSSC have higher post-fire bearing capacity and better ductility, and both of maximum response temperature and geometrical parameters of the specimens presented here have great effect on the post-fire bearing capacity and ductility of ceramsite concrete-filled steel short columns after exposure to fire.
