Characterization of the microstructure and mechanical behavior of electro-welded wire meshes: A case study in Colombia

Abstract

This article presents an experimental evaluation of electro-welded wire meshes featuring bars ranging from 6 to 8 mm in diameter, focusing on their monotonic tensile and cyclic behavior. Microstructure and hardness characteristics are analyzed, and their correlation with tensile and cyclic properties is investigated. Results are contrasted against industry standards and previous research. The study delves into the cyclic stress-strain response, assessing energy dissipation capacity, material cyclic degradation, and kinematic hardening. Additionally, two methods are employed to evaluate the potential for bar buckling. The findings underscore limited ductility capacity hindering earthquake-resistant structural applications.
