Study of Post-fire Performance of Steel Fiber Reinforced Ceramsite Concrete Filled Steel Tubes
The post-fire behavior of a set of steel fiber reinforced lightweight aggregate concrete filled steel tubular short columns (noted as SFLC-SSC) aider exposure to fire was experimentally studied.Effect of the maximum value of fire response temperatures of the tubes and their geometric parameters on the strength and the other mechanical property of the specimens were especially discussed.The experimental results show that the specimens of SFLC-SSC have higher post-fire bearing capacity and better plastic deformation.It was concluded that the maximum response temperature of the specimens has great effect on the post-fire bearing capacity of steel fiber reinforced concrete-filled steel tubes subjected to fire load,and incorporation of 0.5% of volume of steel fiber is best for enhancing the axial compressive bearing capacity of the specimens of SFLC-SSC after exposure to fire.
