摘要：
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. (C) 2016 Elsevier Ltd. All rights reserved.
