Outline of Final Research Achievements

In this study, the influence of high-temperature heating on the pull-out properties of post-installed anchors was investigated by performing pull-out tests of the anchors from constructed concrete structures heated from room temperature to 800°C.
In 2017, influence of specimen size and testing condition on pull-out properties of post-installed anchors was investigated.
And in 2018, the temperature zone of drop of pull-out load occurs was studied in detail concerning each post-installed anchor with specimensize and test condition based on the result in 2017.
