Creep Performance Analysis of Reinforced Concrete after Fire

On the basis of fire test, through the creep test of reinforced concrete structures after fire under room temperature, the stress-strain curves were concluded; then the test processes were numerically simulated, which were also compared with the physical test results. Here elastic deformation and cooling phenomenon in the process of the experiment, exploratory research, relationship between the deformation and cooling rate were also determined, which provide an important theoretical basis for the residual strength structure, disaster assessment and rebuilt after the fire.
