This appendix defines the ASCII file syntax IST requires to create a section table from an ASCII file. You can create a properly formatted ASCII file from an existing section table by using the istdump.exe (see istdump.exe) utility.
When converting an ASCII table file to a section table (binary format), the following rules apply:

Every section must contain 48 records in the following order:
1. Section Type (number from 1 to 18) 
2. Section Name 
3. Section Depth (d) 
4. Flange Width (bf) 
5. Web Thickness (tw) 
6. Crosssectional Area (A) 
7. Flange Thickness (tf) 
8. Flange Thickness + Root Radius (k) 
9. Root Radius 
10. Minimum Number of Holes 
11. Maximum Number of Holes 
12. Section Width/2*Flange Thickness 
13. Yield Strength of Flange (Fy') 
14. Depth/Web Thickness (d/tw) 
15. Maximum Yield for Compact Web (Fy''') 
16. Radius of Gyration * (Flange + 1/3Web) 
17. Depth/Area of Flange 
18. Minimum Fillet Radius 
19. Reserved 
20. Moment of Inertia  X axis 
21. Section Modulus  X axis 
22. Radius of Gyration  X axis 
23. Moment of Inertia  Y axis 
24. Section Modulus  Y axis 
25. Radius of Gyration  Y axis 
26. Torsional Constant 
27. Plastic Section Modulus  X axis 
28. Plastic Section Modulus  Y axis 
29. Shear Center  X axis 
30. Shear Center  Y axis 
31. Centroid  X axis (xbar) 
32. Centroid  Y axis (ybar) 
33. First Moment of Area  X axis 
34. First Moment of Area  Y axis 
35. Radius of Gyration  Z axis 
36. Maximum Principle Moment of Inertia 
37. Minimum Principle Moment of Inertia 
38. Polar Moment of Inertia 
39. Projected Width 
40. Projected Depth 
41. Perimeter 
42. Availability Flag 
43. Shear Area in the X Direction 
44. Shear Area in the Y Direction 
45. XY Moment of Inertia 
46. Principal Axis (tan (alpha)) 
47. BacktoBack Spacing 
48. Warping Constant 

Records must be separated by at least one space; however, there is no limit on the number of spaces.

The characters of any record that requires numbers cannot contain characters other than 09.

If a zero is entered for a property, the value is calculated from the section dimensions.
Section Type Numbers
The section type identification numbers (the first section record) are:
1  Isection 
 solid round 
2  channel 
 thin wall 
3  tee 
 arbitrary 
4  angle 
 concrete angle 
5  double channel 
 inverted angle 
6  double angle 
 joist 
7  rectangular tube 
 half joist 
8  pipe 
 inverted tee 
9  rectangular solid 
 volume
