Evaluation of Mechanical Characteristics of High-Strength Reinforced Concrete Columns with Hexagonal Chicken Wire Mesh Under Cyclic Loading

Abstract Recently, new materials and methods have been implemented to improve the performance of reinforced concrete columns. This paper studies experimentally behavior high-strength columns, with additional internal confinement using hexagonal chicken wire mesh (HCWM) enhance ductility, energy absorption, ultimate strength reduce brittleness traditional Eight double-ended one-third-scale columns different volumetric ratios transverse rebar constructed loaded under uniform axial compression lateral cyclic loads. Different were provided based on special, intermediate, ordinary moment frames specifications ACI 318–14 (named SD, ID, OD, respectively). The specimens confined by rebars HCWM results compared reference ties. Experimental findings demonstrated that exhibited better their control concerning crack efficiency, load capacity, dissipation, failure modes. Implementation increased deformation, absorption OD up 21%, 50%, 175%, respectively, specimen. Confinement ID 15% 22% load, but has a negligible effect SD due enough ratio longitudinal in specimens. As result, could be regarded as simple effective method seismic characteristics RC particularly those members minimal number rebars.
