Plain and Ransome (otherwise known as square twisted or Type 1 deformed) bars were used to reinforce concrete structures in the United States and Canada until approximately the mid-1950s. In Europe, plain bars were routinely used as reinforcement prior to the mid-1960s, while in the UK, they re-emerged for a few years in the mid-1970s, when industrial unrest caused a steel shortage. A significant portion of existing structures are reinforced with plain or Ransome bars, and it has been reported that approximately 70% of concrete structures in Italy are reinforced with plain bars. Although these bars are no longer used in new construction we must understand their behavior to renovate and rehabilitate existing structures effectively.
