Anchor tests ending with concrete failure resulted in severe damage on plain concrete.
CONCRETE CAPACITY DESIGN (CCD) APPROACH FOR FASTENING TO CONCRETE
Test results showed that pullout capacities of the anchors were not significantly affected by the addition of steel fibers into the concrete.

A constant distribution of tensile stresses is then assumed. Grouted anchors of 16 mm diameter were tested at 80,and mm embedment depths.
In the case of concrete tensile failure with increasing member size, the failure load increases less than the available failure surface; that means the nominal stress at failure peak load divided by failure area decreases.
Bridges and other structures; Design; Highways; I For acl head size, the bearing pressure in the bearing zone diminishes. The authors tested 12 and 16 mm-diameter adhesive anchors at embedment depths ranging from 40 to mm. American Concrete Institute P. Retrieved from ” https: An increase of the anchor’s load-carrying capacity is observed. Influence of member thickness and anchor’s head size”. From Wikipedia, the free encyclopedia.
