Tiivistelmä
Concrete elements such as beams, columns, and walls, can be exposed for an extended period of time to elevated temperatures which will cause deterioration to the properties of concrete. This Bachelor’s thesis aims to show the effect of elevated temperature on concrete and the effect on the capacity of the anchors. Extensive data shows that concrete will lose its compressive strength when subjected to heat. Compressive strength-to-temperature relationships should be taken into account when designing concrete fastener resistance. This thesis is commissioned by AFRY Finland Oy.
The background of this thesis is from SFS-EN 1992-4:2018 Design of concrete structures, - Part 4: Design of fastenings for use in concrete. In the standard, the effect of the elevated temperature is considered only for the case of bonded anchor, for this thesis cast in place anchor will be used.
This study is performed by a literature review, a collection of journals and studies from previous research will be reviewed. Based on the review conclusions will be drawn about whether the design capacity of the anchor should be reduced or not.
