The experiments of post-installed adhesive anchoring systems of epoxy injection resin type were taken in focusing on bond failure (bond strength) during fire and after fire. The following conclusions were recognized by their experiments. 1. Bond strength decrease in accordance with increase of temperature in post-installed adhesive anchors. 2. Test condition of acting tensile load for specimens after heating up has a bigger influence compare to heating up temperature for specimens after acting tensile load. 3. Remaining bond strength have the same performance of normal temperature in short term up to 250 °C after fire and cooling down to air temperature.
