Abstract
This research focuses on the development of a characterization system for large (32 mm), resin-bonded post-installed anchors in concrete in case of an earthquake. It is based on the tests required by ACI 355.4- 11 and its conditions, proposing a new test and test design that meets these since the design proposed in the standard makes the test unfeasible. Tensile characterization tests are carried out on cracked concrete (0.3 mm crack opening), seismic tension (0.5 mm crack opening plus loading cycles) and seismic shear (0.5 mm crack opening plus loading cycles) obtaining guaranteed values (95% percentile) for reduced resistance concretes.
