Abstract:
Adhesive (chemical) anchors are used frequently in both new construction and repair/retrofit projects. Current design codes do not contain rational design procedures for these anchors. An experimental program was undertaken to determine the behavior of these anchors and to develop a rational procedure for their design. The experimental program described in this study involved 97 tensile tests of six adhesive products on the following types of 5/8-in.- (16-mm)- diameter threaded anchors: fully bonded single anchors; partially bonded single anchors debonded over the upper 2 in. (50 mm)]; and fully bonded anchor pairs. A behavioral model based on elastic formulation is developed and assessed. Design recommendations for single and multiple adhesive anchors are presented.
