(a) (b) Fig. 5. Experimental results in terms of pull-out force vs displacement for the anchors with:  10 steel bars (a)  14 bars (b).

The following main conclusions can be drawn: •

The anchors realized with 10 mm bar showed a similar strength of about 46.14 kN and 46.07 kN for the  10_center_0.15 and  10_edge_0.15 test, respectively. The total deformation at the peak strength in the
