The main goal of this subject is the research on the application technology of seismic and corrosion-resistant fire-resistant steel for steel structures, focusing on the service performance evaluation and material design of the seismic and corrosion-resistant fire-resistant steel for steel structures, and the research on the design and corrosion resistance of high-performance structural steel connection joints. Key technologies such as fire resistance evaluation and corrosion resistance evaluation of steel structures in typical environments; compile and revise relevant standards and design guidelines for seismic, corrosion and fire-resistant steel used in steel structures to solve technical bottlenecks that restrict the application of high-performance structural steel for construction in China and form seismic resistance The application of a complete set of technologies for fire-resistant and corrosion-resistant steel ensures the reasonable design and selection of seismic, fire-resistant and weather-resistant steel for steel structures, and accelerates the industrialization of seismic, fire-resistant and corrosion-resistant steel structures.
