Adding a RADIUS to a steel beam in the object libray!

Anonymous — Wed, 18 Aug 2004 08:41:29 GMT

Hi everyone,

I am using ArchiCAD 8.1 and need help on adding a radius on a steel beam so that i can use it as a rafter in a curved roof. I would greatly appreciate it if somebody could help me out by either telling me how to do it or just doing it for me.

thanks.

if I had to script a parametric curved beam I'd use the tube command.
Alternatively build it on the plan ( as if in elevation view ) project it in 3d elevating from the top ( so you see the real top) and the save as GDL object.

There probably is a standard object that does it, but someone else will have to direct you to it

hi,

i am new to making or editing objects so i dont know alot about them.

what do you mean by the tube command?

thanks

it is one of the more complex commands. I suggest you look at the GDL manual.

hi.

here is the beam that i am trying to add a radius too. if anyone can help i would really appreciate it.

thanks.

2 easy methods

1-gdl object

'web beam curved' object in the standard library

building structures>steel structures>spaceframes

it's got holes in it

just give the holes a zero radius and they'll go away

2-trussmaker

draw an arc in a S/E window for the centreline of the beam

select arc

menu>extras>trussmaker>create truss

set type, orientation and size of profile

(increase curve resolution for a smoother beam)

Or you could just draw it using the Slab or Wall tool. That would work, as is, or if you're ambitious it could be saved as a GDL object. The User Manual has a good description of saving GDL objects.

Thanks for your replies.

i know about the "web beam curved" but i want to be able to
curve the beam that i have posted. as it allows you to select the section type and weight easily.

thanks again.

actually on closer examination the tube command cant follow a curve path

Using the TrussMaker you can specify your sections.

Thanks Djordje i will give that a try.

Just for the sake of discussion: if it is a circular path then you can probably use the sine and cosine method for setting y and x values for each point that DNC makes so much use of in his Cookbook. I think. Sort of. If on the other hand it is a parabolic or hyperbolic or catenary or other path, then err of course you know the formula.

Is it an I beam you are after? I made a couple of curved beams a while back I could let you have.

That is exactly what i am looking for. Does it allow you to select the type of beam eg. 250 UB 27. if not its still ok. if you dont mind can i get a copy of it?

Thanks for your help.

I've uploaded an Archive file here... http://homepage.mac.com/fuzzytnth3/TLOTT/

You have to type in the overall size of the beam and flange and web sizes less laborious to script that way

Enjoy
