- Synopsis
- Testing and Behavior of Post-installed Anchors in Cracked concrete is to verify the extent to which the tensile capacity of post-installed anchors is affected when cracks are opened in a concrete specimen after the installation. While this testing is less familiar in Japan, it is implemented at standard in Europe by European Technical Approval Guideline (ETAG). Cracked concrete testing in Japan according to the ETAG was applied and this report delineates the testing process and behavior in cracked concrete. The tensile capacity of post-installed anchors in the presence of cracks was found to be 23% to 85% for bonded anchors, and 39% to 100% for mechanical anchors, as compared with the non-cracked concrete.
