Abstract

Highlights: Mechanical properties of welded-wire meshes (WWW) in Mexico are assessed. Parameters are compared to those specified by Mexican and European codes. Mechanical properties are proposed for computing stress-strain curves. Recommendations for improving test and welding methods are presented. Welding procedure can affect significantly to the smaller wires. Abstract: Previous experimental studies on the seismic behavior of concrete elements reinforced with welded-wire meshes (WWM) have suggested that WWM do not comply with the mechanical properties specified in Mexican material standards. To thoroughly assess the mechanical properties of WWM available in the Metropolitan Mexico City, an experimental research program was developed. Based on a statistical analysis of measured mechanical properties, main parameters (yield stress and yield strain, ultimate strength and ultimate strain, elongation after fracture, reduction of cross-sectional area, shear strength of welding, and bending capacity) are reported and discussed. Values of the mechanical properties of WWM are proposed for computing stress-strain curves.
