Since the introduction of strength design for post-installed anchors in IBC 2000, determining the designed capacity of anchors has become increasingly complex. Dozens of variables, such as geometry, concrete conditions, and the specific properties of different anchor types, make a quick, straightforward comparison of design options almost impossible. Leaving behind printed tables and digital spreadsheets, many manufacturers now offer software to simplify anchor design and provide design feedback in real time. Simpson Strong-Tie offers Anchor Designer software to specifiers as a free, intuitive design tool that streamlines the anchor design process.
Have you ever been involved on a project where a post-installed anchor failed when loaded? What was the circumstance? Was the anchor installed with incorrect torque or was the hole improperly cleaned, resulting in lower capacities than published? Unfortunately, in the world of concrete anchors, installations are sometimes incorrect as a result of not following instructions. Alternatively, perhaps you’re working on a project where special inspection wasn’t performed as required by the building code. What should be done in these cases?
