Effect of TMT Bar Lugging on Steel Reinforcement Failure Mode under Monotonic Loading
Abstract: Thermo-mechanically treated (TMT) ribbed bars modify the overall progress of failure in reinforced concrete. The ribs maintain anchorage after friction on the rest of the bar is eliminated during deformation, taking up the ultimate compressive load. This however, is inadvertently jeopardized by the stress concentration effect of the rib geometry. This paper analyses the extent to which some of the geometric forms of bar lugging affect the prevalence of ductile …
