4 Load Capacity of Bonded Anchor Tested Experimentally
and Comparison to the FEM
From the carried out experimental tests, results are shown for each case: three-layer
solid elements with an anchor at 90°, one at 60°, 45° and an anchor at angle 30°
in the single-layer concrete block element. The results obtained in the experimental
research (19) and the FEM numerical simulation of the analyzed models are summarized and compared in Tables 2, 3, 4, 5, 6, 7, 8 and 9 and in graphic form describing
the force-displacement relationship in Figs. 15, 16, 17, 18, 19, 20 and 21. Preliminary simulation tests using the Finite Element Method are intended to compare with
