AB  - This study set out to find a practical method to secure the stability of a supporting structure in cases
of tower crane or large formwork in which the use of a reinforcing anchor body is inevitable. The parameters
of reinforced concrete reinforcement were determined as the diameter, type of anchor and embedded depth. The
concrete compressive strengths used in this experiment were 21, 24 and 27 MPa which are generally used on
construction sites. Reinforcing steel bars of D13, D16 and D22 diameters were also used and the strengths and
failure modes were investigated in these different conditions. The following conclusions were drawn from the
experimental results. The experimental results for the D22 reinforcing bar showed that anchors can be designed
and fabricated in a balanced manner when the ratio of the reinforcing bars to the cross-sectional area of the
concrete is maintained above 0.95%. The increase in the cross-sectional area of reinforced concrete as compared
with the surface area of reinforced concrete is about 2 or 3 times. This suggests that in order to increase the
tensile strength of reinforcing bars, a method to optimize the landfill depth rather than the diameter of the
reinforcing steel bar can easily be applied on construction sites.
