| Abstract: | In order to study the feasibility of high strength concrete for the main frame and structure of a large-scale power plant,the experiments on 6 reinforced high strength slender columns under cyclic loading are conducted.The failure shape and hysteretic characteristics are discussed,and factors such as the axial load ratio,lateral reinforcement forms and the stirrup ratio that affected ductility of the components are analyzed.Based on ANSYS simulated load-displacement of high strength concrete frame columns,a limit axial compression ratio for various conditions was determined. |
| Keywords: | high strength concrete axial compression ratio stirrup ratio hysteretic properties ductility hysteretic energy |
