Setting	Description
Group	The group number. Each group consists of a maximum of two strands. For more information, refer to Strand Groups.
# of Strands	Number of strands in this group.
Y end	Location of the group, measured from the bottom of the beam, at the end of the beam.
Y mid	Location of the group, measured from the bottom of the beam, at the midspan.
Pull	For each group, you may change the initial pull (jacking) of strands. The default value is the value specified in the prestressing tendon library (which is accessed by selecting the Prestressing Tendon item from the Libraries menu).
End Debond	The debonded length at each beam end, measured from the precast beam end.
Midspan Debond	The total debonded length at midspan if using midspan debonding/shielding. Usually equal to zero. For example, a value of 5.0 ft indicates 2.50 ft on each side of the midspan.
Auto Debond Button	Use this button to automatically generate an optimized debonding pattern. Only straight strands can be debonded. See Automatic Debondingand Critical Point.
