Using steel mesh as internal reinforcement in the concrete supports subjected to partially compressive load

Certain concrete components, such corbels, column-footing joints, and post-tensioning prestressed parts, require the load to be transferred from a small region to a broad area. The behavior of the concrete under the impact of local bearing load must be studied in order to transfer the load between concrete pieces securely. The interior core of the concrete supports that are partially compressed is contained by means of steel mesh fabric (SMF) reinforcement in this study. Fifteen concrete blocks were constructed and subsequently subjected to local bearing loads by a steel plate with various areas. SMFs shaped like a box and a cylinder were used as internal reinforcement in the concrete core of the block samples. These SMF patterns varied in volume ratio (V = 0 to 0.4%), form (box or cylinder), and height (h = 0.5 and 1 of block height). Failure mechanisms, bearing stress-slip curve, initial fracture load, ductility, bearing stiffness, ultimate bearing strength, and ultimate corresponding slip of the bearing plate were all discussed for the samples under examination. The first fracture stress of the SMF-reinforced block samples was 30-180% greater than that of the unreinforced sample, according to the results. SMF-samples' bearing stiffness was unaffected. The bearing strength, related slip, and ductility were 45%, 88%, and 118% and 42%, 90%, and 99% and 102%, 123%, and 167% greater than those of the control sample when box SMF with lengths of 1, 2, and 2.6 times the bearing plate area was used. Changing the height of the SMF has only a little effect on the bearing strength ratings of the concrete blocks.
