| Abstract: | Fire is one of the main factors affecting the steel structure design.This paper analyzes the general study of Tireresistant steel structure designs and points out the flaws for various methods.Through the fire resistance performance study of steel structures,in the light of the common European standards,the mechanical properties of steel under high temperature have been analyzed and calculated and the more practical stress-strain relationship has been obtained. |
