Bond and ductility of concrete reinforced with various steel bars surface and ductility conditions

[摘要] Reinforced concrete is a wide field for researches and studies in civil engineering subject. It is due to the fact that reinforced concrete is the most widely used material for the infrastructure in the world. Reinforced concrete consists of two main materials: reinforcing steel and concrete, each of those two materials has its own effect on the performance of the structure. In this thesis, the change in RC performance due to different steel properties and specifications will be investigated. The study focuses on the bond interaction between steel and concrete and the flexural behaviour of RC beams. Pull-out forces have been exerted on the reinforcing bars in RC blocks to examine the impact of steel properties on the bond strength and failure mode of the blocks. In addition to that, flexural tests have been conducted on simply supported RC beams to investigate how reinforcement properties can affect the ductility of reinforced concrete. Comparison of results of the previous two tests with codes and analytical models have been carried out to verify the outcome of this research.
