Abstract text:
An experimental study on the metal expansion and bond anchors behavior post-installed on cracked and non-cracked concrete specimens tested in tension is presented. Mechanical anchors used are the type of anchor bolt or sleeve expansive and the bond anchors are the type with resin glass capsule system of two components. The mechanical and bonded anchors are depicted by the anchors strength, displacement of the loaded end at the control and failure load and also by the failure mode of anchors and the specimens. The pull-out tests were performed according with the European standards. The results obtained on mechanical and bonded anchors show the influence of crack width in reinforced cracked concrete member on displacement before load end failure, load capacity, in comparison with the tests on anchors in non-cracked concrete member and the modes of failure of the anchors and specimens.
Key Words:
bolt anchor; sleeve expansive; bond anchor; cracked concrete; non-cracked concrete.
