| Abstract: | In construction industry, the application of high-performance reinforcement bar is required strongly. Unfortunately, not nearly enough research has been conducted on high-performance steel in comparison with high strength concrete. This paper describes the effect of high-performance steel as reinforcement steel bar on the tension response and cracking behavior of concrete and fiber-reinforced strain-hardening cement-based composite (SHCC) tension members. High-performance steel is characterized by higher strength in comparison to ASTM A615-06 Grade 60 steel. The tension stiffening effect on high-performance reinforcing bars embedded in cement-based composite prism is investigated experimentally. The variables in the study are types of cement-based composite (conventional concrete, synthetic fiber-reinforced cement composite), yielding strength of steel bars (400MPa and 600MPa), and types of loading (monotonic and repeated tension loading). |
