~PCCBPA

 

~PCCBPA, x, y, z, T, p1, p2, p3, q1, q2, q3

Defines a free prestressing tendon

SOLUTION : PRESTRESSED CONCRETE: Free tendons

x, y, z

Point coordinates.

T

Tension of the cable at the defined point (force units).

p1, p2, p3

Tangent vector to the point’s previous segment.

q1, q2, q3

Tangent vector to the point’s subsequent segment.

Notes

- At the initial point: p1=p2=p3=0.

- At the final point: q1=q2=q3=0.

- At the intermediate points, with continuous derivative among sections: p1=p2=p3= q1=q2=q3=0.

- If (p1 p2 p3) and (q1 q2 q3) are different than zero, the point is angular or singular.

- The points are introduced in order. The lines join consecutive points.

- The ~PCCBPA command must be included in the definition loop of the prestressing cables the beginning of which is carried out with the ~PCCBST command and ends with the ~PCCBEND command.
