Title: Fire Resistance of a Prestressed Concrete Floor Panel
CONCRETE FLOOR PANEL-.

Abstract:General fire resistance features of conventional reinforced concrete and prestressed concrete are compared. Results are given of a 4-hr standard ASTM fire test on a 16 x 16-ft prestressed floor panel having an edge beam and an interior beam. Both beams and the 6-in. floor slab were post-tensioned and the cables were not grouted. Temperatures at several thermocouples on the steel cables and in the concrete were observed during the test. With a 1 1/2-in. clear protection for the slab cables and a P-in. clear protection for the beam cables no structural failure occurred during the 4-hr fire test. The temperature rise of the top surface of the 6-in. slab exceeded the allowable after 3 hr 51 min
