Investigation of bond of deformed bars in plain and steel-fiber-reinforced concrete under reversed cyclic loading Panda, A. K.
Abstract
The influence of reversed low cyclic loading on the bond behaviour of deformed bars in plain as well as steel-fiber-reinforced concrete has been studied experimentally and is discussed in this thesis. In total, ten specimens consisting of two plain concrete and eight steel-fiber reinforced specimens were tested to failure. The variables were the mix proportions, the size and shape of the steel fibers and the pattern of loading. The results indicate that the most important factor affecting bond or stress transfer is the peak stress reached in the previous cycle. It was observed that steel-fiber-reinforced concrete exhibits higher bond strength, improved stiffness and less bond-deterioration under reversed cyclic loading than plain concrete. It was also found that steel fibers make a definite contribution to crack control and better serviceability.
