Development of the Research on Fire-Resistance of Structures

The properties of strtuctural material are greatly varied in high temperature caused by fire,which lead the damage or even collapse of structures.The fire-resistance of structures is paid more and more attention by academics and engineers.The history of the research on fire-resistance of structures is briefly reviewed and the main progress in the research on the fire-resistance of structures in recent years is presented.The remained problems for the fire-resistant design of structures is pointed out and the key problems needed further research on fire-resistance of structures are proposed.
