Lecture
This lecture covers the determination of sections subjected to fire action, verification of their resistance, and calculation of necessary loads for structural elements. The instructor explains the process step by step, including calculating roof loads, determining column reactions, and assessing the fire resistance of beams. The lecture emphasizes the importance of correctly calculating loads and understanding the factors affecting structural fire resistance. Students are guided through the process of determining the fire resistance rating of structural elements and exploring different solutions to achieve the required resistance level.
