7. Conclusion

The fire resistance of steel and steel-concrete structures is a complex field that requires careful attention to a number of variables, including fire exposure duration, load types and thermal protection methods. Standards such as Eurocodes 3 and 4, as well as advances in numerical simulations, offer valuable tools for assessing and improving fire resistance. Solutions such as the use of fire-resistant materials and thermal protection systems are crucial to minimizing risks and ensuring greater safety in the event of fire.
