EXPERIMENTAL STUDY ON ANCHORAGE BOND IN HIGH STRENGTH REINFORCED CONCRETE BEAMS

ABSTRACT This paper discuses experimentally the effect of steel bar diameter and embedment length on the bond stresses, bond stress versus slip relation, failure pattern and load versus deflection response of high strength reinforced concrete beams with dimensions (100 mm width x200 mm height x1100 length). Four beams specimens were provided with three embedment lengths (80 mm), (100 mm) and (120 mm) in addition to two different bar diameters (10mm) and (16mm). The test results concluded that the bond stresses and the relative displacement decrease with increasing the embedment length and bar diameter.
