The effect of fire on the flexural behaviour of rc beams is investigated. Four groups of rc beams were cast, exposed to fire at 650°C for time durations of 0, 30, 60 and 120 min and then cooled by water. The concrete compressive strengths of the beams were determined nondestructively using a Schmidt hammer. The beams were tested in flexure by applying two transverse loads incrementally. Strains...
