BOND INFLUENCE ON ROTATION CAPACITY OF HIGH-STRENGTH AND NORMAL STRENGTH CONCRETE BEAMS

The characteristics of steel and concrete have been changing over the years, and this has led to the necessity of new studies on how rotation capacity and the degree of moment redistribution in continuous beams can be affected. Among the factors that have influenece on the behavior of plastic hinges, one could mention the material dependent parameters: steel strength and ductility, concrete strength and bond quality. This work is part of a study on moment redistribution in continuous beams that aimed to verify the effect of bond on the rotation capacity of high strength concrete (HSC) beams. For the sake of comparisons, normal strength concrete (NCS) beams were also tested. The results of this work have indicated an effect of bond on the plastic rotation capacity of both HSC and NSC beams. As for the plastic hinge length, no effect has been detected, but this should be further investigated.
