Creating a Circular Hollow Section in Teddy

Hi Everyone ,
I am trying to develop a circular hollow section with a diameter of 139.7mm and a thickness of 4.0 mm. My teddy code is as follows
+PROG AQUA urs:2
head Materialdefinition
norm EN 199X-200X-BRIDGE cat D $ Straßenbrücken
page unii 2 $ Einheiten (Querschnitt: mm, System: m)

!! Materialdefinition
stee 1 S 355N tmax 0 titl 'S 355 (maxd=40mm) (y=y)’

end

$----------------------------------------------------------------------------------------------------------------------------
!+!Kapitel QS#01_FEM: Circular Hollow Section
$----------------------------------------------------------------------------------------------------------------------------
+PROG AQUA urs:5
head Querschnitt 01_FEM
norm EN 199X-200X-BRIDGE cat D $ Straßenbrücken
page unii 0 $ Einheiten (Querschnitt: m, System: m)

!*! Parameters (No calculations)
tvar CHS_D 0.139 $ [m] Outside Diameter
tvar CHS_t 0.005 $ [m] Wall Thickness
tvar CHS_R 0.0695 $ [m] Outer Radius (half of CHS_D)
tvar CHS_Ri 0.0645 $ [m] Inner Radius (CHS_R - CHS_t)

!*! Define Circular Hollow Section
hsec 013
CIRC R 0.0695 $ Outer Radius (CHS_R)
CIRC R 0.0645 NEG $ Inner Radius (CHS_Ri)
end
Ikeep getting the same error

Kindly assist because I am a beginner in teddy. Thank you in advance.

Hallo,

the error comes due to input NEG at CIRC R 0.0645 NEG $ Inner Radius (CHS_Ri). In addition, the input record SECT is also missing. When you want to use the TVAR variable for the radii in a later AQUA run for the cross section interpolation along an axis the input hast to be as follows:

!*! Parameters (No calculations)
tvar CHS_D 0.139 $ [m] Outside Diameter
tvar CHS_t 0.005 $ [m] Wall Thickness
tvar CHS_R 0.0695 $ [m] Outer Radius (half of CHS_D)
tvar CHS_Ri 0.0645 $ [m] Inner Radius (CHS_R - CHS_t)

!*! Define Circular Hollow Section

sect 1 mno 1
CIRC R “=#CHS_R” $ Outer Radius (CHS_R)
CIRC R “=#CHS_Ri” mno 0 $ Inner Radius (CHS_Ri)
