| 要旨 |
The effect of reinforcement corrosion on bond creep characteristics is investigated experimentally through pull out in long-term under corrsion degree in range of 0.5 to 0.7% of mesured mass loss that corresponds to average corrosion crack widths, before loading, in range of 0.2 to 0.3 mm. As a result, bond stress/strength ratio larger than or equal to 60% would cause creep failure, when corrosion degree is less than 0.7% and corrosion crack width is wider than or equal to 0.2 mm, after a loading period that depends on the applied bond stress/strength ratio with negligible effect of load histoy.
