Abstract:This paper describes and comments on AIJ Design Guideline 2010 of post-installed bonded (adhesive) anchor. This paper presents tension tests to clarify the influence of the embedment depth and the edges on the tensile behavior of a single post-installed bonded anchor. The 4 parameters of the test are established; embedment length (le = 7da, 14da and 21da; da: anchor diameter), edge configuration (anchorage at an edge, a corner and thin member), edge distance and adhesive system (glass capsule type, film foil type and injection type). In those tests, we investigated failure mode and failure load of bonded anchor close to the edge(s), and discussed about resistance of anchors to tensile load. Further, the method to estimate the tensile strength (failure load) of single-anchor or of anchors in the groups was proposed with the influence on edge(s). The method in bond failure type is modeled based on a uniform bond stress, and the uniform bond strength is evaluated with reduction coefficient which considered the number of edges and the edge distance.
