Construction steel will be affected by high temperature and corrosion,resulting in a decline in the mechanical properties of steel components,which may lead to safety problems in the building and is not conducive to the normal use of the building.Based on this,this paper studies Q355 steel commonly used in building steel frames and walls,analyzes the mechanical properties changes of Q355 steel under the combined action of high temperature and corrosion,adopts two methods of corrosion before high temperature and corrosion after high temperature,analyzes the mechanical properties changes of steel structures under different actions,and summarizes the changes of steel properties.
