AERODYNAMIC SHAPE FACTORS for BEAMS
AERODYNAMIC SHAPE FACTORS for BEAMS
(OP)
AS 1170.2 Tab E5 has drag force coefficients; Cf,x andCf,y; for UB/UC type sections for d/b ratios of 0.48 and 1.0.
Does anyone have similar data for other beam sections?
Is there a general formula for coefficients for varying d/b ratio?
The following seem to fit but there are only two points to work from.
Cf,x(θ=0deg)=2.5-0.9*(d/b)
Cf,y(θ=90deg)=-1.9*(d/b)
where 0.0<=(d/b)<=1.0

now I know where AS1170.2 gets its values from. Unfortunatley it adds no further information.
