Experimental Research on Fire Response and Post-Fire Bearing Capacity of Profiled Sheet-Ceramsite Concrete Composite Floor

Abstract:

Compared with ordinary concrete composite floor, profiled sheet-ceramsite concrete composite floor(PSCCF) has the advantages of lighter weight and higher strength, and its resistant fire characteristics is better than ordinary concrete composite floor for stability of characteristics of ceramsite under high temperature. For study of the characteristics of the floor after fire, the experimental research on bearing capacity of the profiled sheet-ceramsite concrete composite floor after fire and the floor not subjected to fire load are further carried out at indoor temperature here. Based on the experimental results, effect of the fire on post-fire bearing capacity of the profiled sheet-ceramsite concrete composite floor is discussed, and the failure phenomenon and mechanism are analyzed. It is shown that he failure form of the profiled sheet-ceramsite concrete composite floor after fire has great change compared with the floor not subjected to fire load, but the bearing capacity of it is still higher.
