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
