ENINEERIN Fire Resistance of Reinforced Technical Note

Additional fire-resistance rating criteria include: • For unrestrained reinforced concrete members, in some cases, the average temperature of the ten-sion reinforcement at any section must not exceed 1100°F. For restrained reinforced concrete beams spaced more than 4 feet on centers, the 1100°F temperature must not be exceeded for fire ratings
