6.2.1.3. Draw-in
draw-in influence distance at cable,
xd = SQR(dr . Ep . Ap / m)
where :
dr = draw-in occurred of used system,
at VSL system, draw-in is = 0.006 m.
Ep = Elasticity of prestressing steel
For used strand, Ep = 1.95E+6 kg/cm2.
Ap = total area of used strands,
namely = 60.213 cm2.
m = inclination of force from diagram,
