36、 fixture, which can be a structuralelement, to the base material;b) there is a wide variety of anchors available for different applications.Every anchorage has three elements: anchor: the device that fastens the fixture to the base material; base material: the material into which the anchor is insta

37、lled; fixture: the item to be fixed to the base material.The performance of anchors is influenced by many application parameters,which need to be taken into account in their selection. Performance is alsoaffected by the quality of installation.If anchors are not selected and installed correctly, the

38、y might not have thecapability to resist loads as intended. The security of the fixture and, in somecases, the structure might then be compromised, leading to failure withconsequential economic loss, injury, or even death. This British Standard isintended to facilitate all stakeholders involved in t

39、he use of anchors to achievethe security required by the design.Figure 1 shows a simple outline of the overall approach to be taken to ensurethat connections are safe and that they meet the overall design requirements.Figure 1 Flowchart for overall process of selection and installation of anchorsBRI

40、TISH STANDARD BS 8539:2012 The British Standards Institution 2012 11 ScopeThis British Standard gives recommendations for the safe selection andinstallation of anchors for use in concrete and masonry. It is intended to providepractical guidance for designers, specifiers, manufacturers, suppliers, co

41、ntractors,installers and testers of anchors.In particular, this British Standard applies to the selection and installation ofanchors which are used in safety-critical applications.This British Standard is restricted to the use of anchors which are inserted intoconcrete and masonry in drilled holes.2
