Solved: Numbering of main parts - how to exclude bolted connections from one main assembly

Hi everyone,

I'm relatively new with using AutoCad Advance Steel and I've seen that this question has been asked before but previous answers haven't helped, so I'm posting it again.

Currently I'm working with a platform that is relatively complex and I have to divide it into smaller assemblies. I want to divide my platform into smaller assemblies in a way that one assembly does not have any bolted connections inside itself. My problem now is that the program divides platform in a way that in one assembly there are few bolted and few welded connections. I want that one assembly has inside itself only welded connections.

I attached my 3D model, and a screenshot of concrete problem with one assembly bellow so you can see my problem by yourself. Hope that someone will help me and thank you in advance.

HI!

maybe try to use filters to exlude elements whats not needed.

Hi,

i would recommend u devide your columns, diagonales and crossbars. When i check your model, there are some things which are just wrong. Try to delete some of the boxes which created your connections. You have to becareful where your weldings are, especially at the cross beams.

I would do the following steps to create the assemblys.

1. Delete all weldings

2. Create the columns as 1 assembly each.

3. All diagonals with their plates at the ends 1 assembly each.

4. The platform on top can be 1 assembly. Length, width and height look okay in my opinion.

Note: Some bolts cant be mounted. Dont forget collision control.

I attached a model how it should be down. Simple steel construction...

Hi @s_hannemann ,

I have listened your advice and I deleted some of the connection boxes and welds. Then, I deleted columns from the current model and made them again from scratch. I reestablished connections between columns and plates that are welded on them and it solved my problems. Now, the platform is divided into 4 columns assemblies, 1 horizontal framework and few diagonal steel profile assemblies.

Regarding your comment on bolt, I think that it can be mounted. I agree that it is not easy to access that bolt but in this case, all the connections between column assemblies and diagonal steel profile assemblies have to be done with bolts because of the galvanization process.

Thank you again for your advice, it was helpful!

Hi,

glad i could help. Most of your bolts were okay. Just 2 or 3 were a bit critical i guess. Most of the times diagonales are round, U or l-shaped thats why u can mount the bolts easily and they are enough for the tensile and compressive stress. I dont like using I-shapes as diagonales because they are just good against bending (Iy)...
