In order to explore the applicability of rebar HRB600 for concrete flexural members under normal service conditions, five reinforced beams with and different reinforcement ratios, diameters methods were designed fabrcated. The bending performances test above specimens carried out by three-point loading method. results showed that overall (crack development, failure modes ductility) same as beam ordinary rebars. calculation deflection values took quasi-permanent combination considered long-term load action could meet limit requirements code GB 50010-2010. However, crack width corresponding not limit. reasons exceed limits, especially measures reduce members, analyzed.
