| Research Abstract |
The fracture of reinforcing steels in concrete structures deteriorated by alkali silica reaction (ASR) has been reported. That may be attributed to the excessive expansion due to ASR. This study describes a load carrying capacity of concrete structures affected by ASR. The maintenance scenario, which can consider the remedial measures for the deteriorated structures and the maintenance after applying the remedial measures, was also proposed.
