Autocad Lisp Steel Sections Tables

Autocad 2012-2017 (and verticals) Windows 7/8/8.1/10 AreaMeasure is a multi-units custom AutoCAD plugin that helps the user create measurements of polygons, providing a dynamic area field with auto numbering system and an AutoCAD table containing the measurements of polygons including a summary total.

When building my data base for steel shapes I had to combine three data bases before I got something that was close to my CISC handbook. I used the AISC and CISC data bases supplied with ADT and an old data base on a cd supplied by the CISC. Not one of the three data bases supplied matched the CISC handbook. Also none of the data bases had any information regarding the toe radius. The standard channel shapes drawn by the Detail Component Manager supplied with ADT from either AISC or CISC are drawn with a short vertical segmant at the toe. The toe radius column in the data base contains only zeros. AutoCAD draws the toe radius Rt equal to the root radius Ri.

I assumed the same. The geometry is not indeterminate.

It can be constructed with the vertical segmant at the toe. I have not measured an actual piece of steel. I too would be interested in the response from AISC.

Reply from AISC. I've followed up with some other questions and I'll post those answers when I have them. Jason, Radii of fillets and toes of shape profiles vary with individual manufacturers and therefore are not specified in the ASTM A6 Standard which covers the Generals Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling.

I'm trying to find out if we have an ASTM A6 manual so I can see what type of guidelines they provide. I also talked with one of our local steel guys, who just happened to stop in here yesterday, and he can get me some scrap pieces of whatever I need.

So I should have a piece of channel and angle some time soon. He did say the radius at the toe of an angle is probably tighter than I think. I'll keep you posted with any further updates.

There is no specific tolerance that manufacturers must abide by in this respect. Section properties of rolled shapes are mainly controlled by the tolerance on weight, depth, flange width, web thickness, etc. As previously stated there is no specific tolerance on the fillet dimension which will likely vary from manufacturer to manufacturer depending on the design and wear on their rolls at any specific time. AISC does a survey of various manufacturers from time to time, for each shape listed in the Steel Construction Manual, to see what the maximum and minimum radii values are running for any particular shape; then uses the most conservative value in deriving the section properties that are listed in the Manual.
