Hadi, M. N. (2007). Modelling of high strength concrete reinforced with helical reinforcement. In B. H. V. Topping (Eds.), International Conference on Civil, Structural and Environmental Engineering Computing (p. [18]). Stirlingshire, UK: Civil-Comp Press.


This paper investigates the behaviour of high strength concrete beams reinforced with helical reinforcement in the compression zone. Using helical reinforcement increases the strength and ductility of high strength concrete. The finite element packages ANSYS and Strand7 have been used to model high strength concrete beams with helical pitches of 25, 50, 75, 100 and 150 mm. Three dimensional elements were used to model the concrete and bar elements to model the steel.Special care had to be taken when modelling the helices. The results of finite element analyses were compared with experimental results which showed a good correlation.
