Abstract
There are several aspects related to ASR problem in concrete structures which have not been fully studied. One of these problems is the structural effects of ASR on reinforced concrete (RC) structures. For example, the characteristics of internal stress of ASR-ffected RC members under sustained load is not fully explained. The first object of this study described here is to investigate the characteristics of internal stress of ASR-affected RC beams and RC columns under sustained load. The second object is to evaluate the structural effects of concrete surface coating on ASR-affected RC beams and RC columns under sustained load. In this paper, laboratory test results and some structural analysis results are presented, and also some discussios are presented.
