Abstract

After measuring and analyzing the experimental data of sixteen full_scale simple reinforced concrete ( RC) beams, the temperature distribution on the section is obtained, the generalities of mechanical performance and deformation of members are concluded, the influences of heating time and reinforcement ratio are investigated. The residual bearing capacity of members after elevated temperature is the basis for the restoration and reinforcement. Through experiment, it is explored that the influences of heauing time, reinforcement ratio and different methods of cooling on the mechanical performance of members after elevated temperature. It offers a basis and methods for the analysis of fire resistance of concrete structures.
