Difficulty Understanding Program Tendon in Teddy

Hi Guys, greetings from Toronto.

I’m new to Sofistik and trying to learn to work with Teddy. However, I’m having difficulties understanding Teddy Manuals for syntax and commands for Tendon Program defining tendons for a precast prestressed girder.

I got this example from a friend but still hard to fully get the point:

+PROG TENDON URS:3
HEAD

$ !!! MUE 0 BETA 0 DO AND AZ SHOULD MATCH
SYSP NOPS 12 MAT 2 ZV 2922 AZ 50^2*#PI/4 LITZ 1 MINR 5 BETA 0.3 MUE 0.000 ECC 0 SP 0 DO 1 $

AXES NOH 1 TYPE NODE 1 2
TOPP NOH 1 KIND NODE S 1,2 SP 1,2
TGEO NOG 1 NOH 1 NOPS 12
PTUV S U V DVS TYPE=SPAN
1 0 0 -
1.50 - 0 0
2 0 0 -

$ CS ICS2 10 IS FOR IMMEDIATE BOND
CS ICS1 10 ICS2 10
PDEF RI STR 1000 $ [KN]
$PDAT FTL 1.0 FTYP LINE $ FORCE TRANSITION LENGTH

TEND NOT 1 NOG 1 NTEN 1 LC 10

ECHO PLOT FULL
SCHH H2 0.18
PLOT GEOE NO 1 FACH 5 TYPG DUTE PCS 1
PLOT FACT NO 1 FACH 10

END

Could anyone help me decode these steps, particularly for TOPP?

Thanks

General tip:
The automatic “goto command” in the help is great for details.
But if you want more of an overview read the start of the chapter/subchapter and/or the “theoretical principles”
In the case of tendon, this picture in the manual helps a lot:

In your case the duct geometry is defined as:
AXES NOH 1 TYPE NODE 1 2 Axis between node 1 and 2
TOPP NOH 1 KIND NODE S 1,2 SP 1,2 Node 1 and 2 are stations/supports (i.e. a span is between them)
TGEO NOG 1 NOH 1 NOPS 12 The duct is defined as the axis above with a prestressing system
PTUV S U V DVS TYPE=SPAN The duct geometry is defined with respect to the axis (high/low points)

Thank you!
