Abstract: Fire is greatly harmful to the safety and serviceability of concrete structures. In fact, it affects the durability of concrete, which leads to the damage or even collapse of structures. The high temperature caused by fire can aggravate the carbonation of concrete, and there are also other common factors that influence the durability of the post-fire concrete as well, such as chloride corrosion and freeze-thaw damage. Those may speed up the corrosion of steel and worsen the performance of concrete structure, so the standard for the durability evaluation of post-fire concrete structure should be built up urgently. Based on the calculation methods of concrete structure in atmospheric conditions and combined with the engineering case, this paper gives the calculation means of durability failure time and the standard for durability evaluation of post-fire concrete structure.
