structural angle iron question
i'm modeling some things in autocad and i want to make sure i don't have any interferences. i want to use 3x3x3/8 structural angle iron and i've been trying to find out what the internal radius is. any ideas?
find a job or post a job opening
the steel manual only gives you the k distance. k is the distance from the edge to the web when it starts to curve. according to the manual k = .75". that means the inside radius is probably 3/4 - 3/8 = 3/8 "
never, but never question engineer's judgement
hi drewj88
have a look at this site:-
i use 5/16" as the inside corner radius. don't forget the radii on the legs also!
thanks. i'm going to go with 3/8" and design the interference to that and if it is 5/16" i'll be covered. i appreciate the help.
i believe you can get an autocad subroutine with all the shapes online.
yes i believe there are a few programs out there with all of the aisc shapes & properties for autocad. we use a program called steelplus, but i'm sure there are others.
as far as the internal radius, steelplus shows it to be 5/16"

... and 3/16" for the radii on the legs.
