Tensile mechanical properties of the electro-welded wire meshes available in Bogota, Colombia

摘要

Concrete members reinforced with electro-welded cold-drawn wire meshes have experimented deformation capacity lower than that of elements reinforced with conventional ductile reinforcing bars. The tensile mechanical properties of the electro-welded wire meshes available in Bogota, Colombia, are experimentally assessed in this paper. The mechanical properties evaluated were the yield strength, tensile strength and ductility capacity of the wires in terms of the area reduction, ultimate-to-yield strength ratio, and strain ductility capacity. A statistical analysis allowed contrasting the actual mechanical properties obtained in the experimental campaign, with nominal properties specified by manufacturers and standards. Stress-strain curves of the wires were proposed for code-based design. (C) 2018 Elsevier Ltd. All rights reserved.
