Most of papers and reports on concrete structure member deformation characteristic affected by Alkali-silica reaction are mainly carrying out at indoor. No report of measurement of deformation behavior that actual structure is measured by long-term observation is available. This paper reports deformation behavior of actual structure due to aging phenomena by observations for long-term period, such as cracks, expansion rate and status of progress. They are emerged as a result of examinations of an actual structure affected by Alkali-silica reaction; the development effecting by Alkali-silica reaction is implicated by temperature condition, external constraint condition of the structure. Mechanical characteristics of concrete such as elasticity coefficient have reduced as same as existing report. Development of cracks has been same tendency as expansion rate, however prediction of expansion rate for actual structure by summarization of cracks tendency is difficult.
