This paper presents a brief overview of bonded anchorage applications while the primary literature review discusses three methods of mechanical anchorage: spike, wedge and clamping.
It is important to note that simplified methods of testing anchorage systems independently are certainly not a substitute for representative tests involving full FRP strengthening systems.
In the experimental program, different types of anchorage methods were tested in a double shear push-out test setup.
Experimental and numerical extraction loads are also compared with the ones resulting from analytical design methods for anchorages under the European Standard ETAG 001, while discussing the problems of their application to these non-certified anchorages.
Two different design methods for anchorages with post-installed reinforcing bars are available: Anchorages can be designed either as end anchorage equivalent to cast-in reinforcing bars or as bonded anchors.
A strengthening coefficient is proposed to identify adequate CFRP bond length that can exploit such a strengthening method (i.e., the location of anchorage for post-tensioning the CFRP).
Recently, delicate traction, indentation, or extrusion of the anterior teeth by modifications of conventional orthodontic treatment methods using anchorage devices such as improved mini-screws or mini-plates have become possible.
Those seven studies reported a significant difference in the amount of anchorage loss between the two methods of retraction.
This finding was surprising as there was a 2.5-mm difference in the amount of anchorage loss between the two methods.
Comparison group 3 reported no significant difference in the amount of anchorage loss between the two retraction methods.
