A CRITICAL REVIEW ON FIRE RESISTANCE STRUCTURES
used fire resistant material. Steel It is a good conductor of heat. Steel bars lose tensile strength. Steel yields at 600°C. They melt at 1400°C. Steel columns become unsafe during fire. Steel reinforcement weaken the reinforced concrete structures. Hence steel columns are usually protected with brick works or by encasing in concrete.
