Article Preview

The post-fire behavior of a set of ceramsite concrete filled steel tubes (note as CCST) after exposure to fire are experimentally studied. Effect of the maximum value of fire response temperatures of the tubes and their geometric parameters on the strength and ductility of the specimens were especially discussed. The test results show that the specimens of CCST have higher post-fire bearing capacity and better ductility, there was no obvious descent segment in post-fire load-displacement curves of the most specimens subjected to fire load. It was concluded that the maximum response temperature of specimens has great effect on the post-fire bearing capacity of concrete-filled steel tubes subjected to fire load.
