afralisp beam

[Arie]

I am working (fighting) with the Beam program .

I want to set the Beam.dat file to metric but I don'nt know wich numbers I have to change.

This is the dat file thats works with the lisp file an dcl file

See attachment

 

**UNIVERSAL BEAMS DATA**----------------------- **H X B X T1 X T2 X R1 **-----------------------

*100x55x8   This are the dimensions of the beam

100.0,55.0,4.1,5.7,7.0    This numbers I don't know what the are

*120x64x10

120.0,64.0,4.4,6.3,7.0

*140x73x13

140.0,73.0,4.7,6.9,7.0

*160x82x16

160.0,82.0,5.0,7.4,9.0

*180x91x19

180.0,91.0,5.3,8.0,9.0

*200x100x22

200.0,100.0,5.6,8.5,12.0

*203x133x25

203.2,133.4,5.8,7.8,7.6

*203x133x30

206.8,133.8,6.3,9.6,7.6

*254x146x31

251.5,146.1,6.1,8.6,7.6

*254x146x37

256.0,146.4,6.4,10.9,7.6

*254x146x43

259.6,147.3,7.3,12.7,7.6

*305x102x25 **------------------------

 

Any help welcome

Your in trouble if you do not understand the basic parameters of say a "I" beam, height, width, web thickness, internal radius. 250UB25 or a 250UB30 what is difference ?

 

Your 1st step should be get a copy of steel sections relevant to where you are in the world. They have charts that indicate the values.

 

Are you using Wiseys steel shapes lisp ?

Once you read the entire program then you would easily know what they are all about.

Isn't it already metric?

 

It certainly not Imperial.

[Tharwat]

They look to me in Millimeter so I guess they want them either in centimeter or meter.

I know the parameters off the beams in Europe.

All I want to know is wich numbers I have to change in the dcl  and lisp file to let it work !

[Tharwat]

If you can post the link to the program then me or anyone else can look at for you.

Yes, that's correct.

The first line (*100x55x8) is the name of the beam. (100 deep x 50 wide x 8 kg/m beam.) The second line contains the physical dimensions that we need to draw the beam. (100.0,55.0,4.1,5.7,7.0) (Height, width, web thickness, flange thickness and root radius.)

What isn't working?

 

You do not seem to be very sure of what you want, now it is the LISP and DCL that need changed?

[Arie]

This are the height ,width , flange thickness of metric IPE.

@Arie

I refer to table from your last reply, the second row (IPE 100):

100 = h

55 = b

4.1 = s

5.7 = t

7.0 = unit length (m) - This figure is missing from your table, you need to get it separately.

I have created the beam from the data and located text represent each variable to its accurate coordinates and this should help you if you also read the program from the top then you would know where did the data come from.

 

Please find the DWG the attachment which should help you a lot I believe.

This is Wiseys steel shapes all the dim files are steel shapes like what your asking for. Yours could be in this list else you can make your own and use the code as is. Lots more shapes than just a "I" beam.
