| Research Abstract |
This study aimed at the evaluation of static and/or dynamic structural performance of ASR-damaged reinforced concrete (RC) members. The second aim is to develop Damage Index which quantifies ASR-damaged degree of concrete by petrographic technique. The Damage Index to evaluate micro-cracks in concrete was correlated with expansion strain of concrete.
From the experimental results, it was made clear that the effects of ASR-damage on static and/or dynamic structural performance of ASR-damaged RC members were small. The results also showed that Damage Index was correlated to mechanical properties of ASR-damaged RC members so that Damage Index was useful to evaluate the ASR-damaged RC structures.
