Fire-resistance of prestressed concrete beams
Beams containing post-tensioned cables were tested for use in buildings where fire-resistance of 4 hr would be required for structural elements; for hard-drawn steel wire, cover of 1 1/2 in. of concrete gives fire-resistance of 1 hr; for longer periods of resistance, secondary reinforcement is necessary to hold concrete cover in place, and cover of 4 in. gives fire-resistance of 4 hr; by further increasing cover, resistance of up to 6 hr may be obtained.
