Abstract

Abstract

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