1. What is ?
Anchors are installed in concrete and masonry members for different purposes such as attachment of steel plates, pipes or ventilation ducts. Anchor Tests measure the strength capacity of the anchor in the connections for different loading orientations.
2. When would you use ?
There are two types of tests depending on the goal: ultimate and proof test. An Ultimate test is carried out until failure of the connection is reached, either by reaching plastic deformation or complete breakage. Ultimate strength/deformation relationship can then be used in design calculations. On the other hand, proof testing is conducted when you want to make sure that an anchor has been correctly installed and not damaged; in this test the anchor is loaded up to a
specific fraction of the rated load (not to failure).
3. What are the Benefits of ?
More important than fixings for ducting and other non-structural elements, anchors are mainly used to strengthen concrete or masonry structures by attaching steel members after damaging earthquakes or for upgrading their seismic rating. As with the basis of any connection design, Anchor Tests can be used to ensure that the connections do not fail before the connecting members.
Both types of tests are conducted according to BS 8359:2012.
