Numerical Investigations on Non-Rectangular Anchor Groups under Shear Loads Applied Perpendicular or Parallel to an Edge

Anchorages of non-rectangular configuration, though not covered by current design codes, are often used in practice due to functional or architectural needs. Frequently, such anchor groups placed close a concrete edge and subjected shear loads. The anchorages requires engineering judgement no clear rules given the codes standards. In this work, numerical investigations using nonlinear 3D FE analysis code carried out on with triangular hexagonal patterns understand their behavior under A microplane model relaxed kinematic constraint is utilized as constitutive law for concrete. Two different orientations considered both while hole clearance analysis. loading scenarios investigated: (i) applied perpendicular towards edge; (ii) parallel edge. results analyses evaluated terms load-displacement failure modes. comparison made between simulations analytical calculations according approaches. It found that, similar rectangular anchorages, also without clearance, it may be reasonable calculate breakout capacity assuming crack from back row. Furthermore, load investigated loaded twice corresponding
