Paper Title:
Research on Post-Fire Bearing Capacity of Ceramsite Concrete Filled Steel Tubular Short Columns
  Abstract

Mechanical behavior and bearing capacity of ceramsite concrete filled steel tubular short column (noted as CCSSC) subjected to fire load are experimentally investigated. Effect of the parameters, such as the maximum value of fire temperatures, fire duration on the strength and ductility of the two types of specimens were especially discussed. The experimental results show that all the specimens of CCSSC have higher post-fire bearing capacity and better ductility, and there was no descent segment in load-displacement curves of the most specimens after the fire load was subjected. It was concluded that the maximum response temperature of specimens and fire duration time has great effect on the axial bearing capacity of concrete-filled steel tubular short columns subjected to fire, and the concrete mix proportion has some effect on both of bearing capacity and ductility of CCSSC subjected to fire load.
