Introduction In china, concrete structure is widely used in civil engineering construction, which is composed by two different nature materials of reinforcement and concrete.
As the structure of concrete is possibly often or accidentally exposed to high temperature environment in real engineering, the performance of concrete material will change and the uneven temperature field inside structure is formed during these exposures.
