Abstract:
The behavior of reinforced concrete columns confined with welded-wire fabric was investigated. Thirty-four small-scale specimens with different reinforcement arrangements, including four corner bars as longitudinal reinforcement and various combinations of welded-wire fabric and tie steel as lateral reinforcement, were tested under concentric loading. The results indicate that welded-wire fabric can be effective in confining the core concrete, resulting in significant improvements in strength and ductility of columns. This improvement, which is achieved with a relatively small percentage of steel, is equivalent to that achieved with closely spaced tie and longitudinal reinforcement with a considerably larger steel percentage. Although some practical problems remain, welded-wire fabric can potentially be used in earthquake-resistant structures as confinement reinforcement.
