INFLUENCE OF CORROSION OF REINFORCING BARS ON THE BOND BETWEEN STEEL AND CONCRETE AT ELEVATED TEMPERATURE
This paper presents an experimental investigation that reveals bond force slip relationships for corroded reinforcing bars under elevated Temperature conditions. The test program consisted of fabrication and testing of 6 pull-out specimens. The specimens were heated up to two levels of temperature (250Co and 500Co) in addition to roomtemperature. The obtained experimental results indicated that for specimens with corroded bars have bond strength higher than specimens with corroded bars at room temperature and that the bond strength reduce with high temperature for specimens with corroded and under corroded bars.
