ASK HILTI TEAM can you help in knowing how to find the length of a post tensioning parabolic strand if we just know the length and height of parabolic curve from one end to other?

Thank you for posting query.

Following Formula can be used to calculate the parabolic arc length –


where:
L is the length of the parabola arc
a is the length along the parabola axis
b is the length perpendicular to the axis making a chord.
