Abstract
<jats:p>The accumulated practical experience in the last two decades of operation of steel structures that have suffered fire damage shows that the reuse of load-bearing steel parts under certain conditions is economically feasible and does not lead to a significant decrease in their reliability. The paper presents the structural examination after fire impact on a warehouse building with a steel load-bearing skeleton without fire protection. Numerical modeling of the fire impact is presented and the critical temperature for the various load-bearing elements is determined. An assessment of the damage caused by the fire impact is made and criteria for operational suitability are specified. The analysis of the results of the structural inspection provides grounds to recommend preserving the integrity of the main structure by replacing the affected bolted joints and renewing the anti-corrosion protection. Structural measures for the repair of individual elements and joints are prescribed.</jats:p>
