Calculation Method of Butt-Welded Connection of Steel Structure Post Fire
In order to study the load-bearing properties of butt-welded connection of steel structure post fire, the strength design value of weld connection post-fire is proposed based on the experimental data and theoretical analysis. Considering the influence of different high temperatures and cooling patterns on strength damage of the weld, a revised checking method for strength of butt-welded connection of steel structure after high temperature is established on the basis of the analysis method for strength of butt-welded connection of steel structure at room temperature. The method can be used for damage assessment and strengthening technique of steel structure post fire.
