| Abstract: | A bond-type anchor bolt has been used as a post-installed type anchor. Recent developments in construction technology have diversified the use of this type of anchor even in a new construction site. Since this type of anchor exhibits a complex failure mode involving cone and bond failure, its design method is still to be investigated in depth. Among the various conditions to be considered, we focus on the effect of a free edge on the pull-out strength both experimentally and analytically. We propose a new method to estimate the cone failure strength using the theory of linear fracture mechanics. The experimental results coincide well with the analytical estimation. The reduction of the strength is much larger than expected by the analysis based on the current design method. |
