Abstract: The effect of using steel strips as a tied reinforcement instead of bar ties to reinforce concrete columns was investigated. Five concrete columns with dimensions 150×150×1150 mm were reinforced with 4 bars of diameter 12 mm as the main reinforcement. One of these columns had a bar tie of diameter 8 mm used as a reference column. The other four columns had strip ties with different widths, 90, 50, 31 and 22 mm and thicknesses, 1-4 mm with an area equivalent to that of the regular ties in the reference beam. A good agreement was obtained between the experimental and theoretical results using the abaqus finite element program. It was found that, using 4 mm thickness plated ties could increase the ultimate load of concrete columns by 17%.
