Structural Connections In Revit 2017

[Anonymous]

Hi,

I'm not a structural engineer but could do with knowing what each of the connection are used for.  Did a quick google and got nowhere really.  However, I have done a couple on my frame, but struggling for what to use when an I Beam meets by square column.

Darren: what is it you want to do exactly?

You can use an L-clip on either sides of the I-beam similar to what shown there. Why are you doing this if you are not an engineer? You need to know the steel gauge, what kind of bolt, how big is the diameter, how many bolts, and what is the spacing.

Funny, I thought @Anonymous was referring to Coping distance, since he already got the Structural Connector placed. Or, maybe his screenshot isn't of  his work and he's just trying to replicate it.

Thanks for the replies.  This is a project I am working on for my Architectural Technology degree so, even though it doesn't need to be absolutely perfect, I need to show that I understand that the steel frame will need strengthening/joining sections when the beams and columns meet.  The image is my frame.  I have managed to do the joints between the I beams but don't know what to use to join the square column to the I beams. There doesn't seem to be anything in the steel connection tab. 

I also keep getting Revit crashing on me when I click on the structural connection drop down tab which is annoying - on the latest version 2017.2 as well.

If you only get the "Generic Connection" in the properties window, then you need to load in the connections.  More than likely this wasn't done if you started with a Architectural Template vs a Structural template.  Click the little Arrow next to Connection and load the connections that you need.

If you keep crashing...there may be an issue with your computer not being compatible with Revit.  Which I believe was the case from an earlier thread that you have an intel video card..(I could be confusing you with someone else...lots of chats come through here)...which is not compatible.

Thanks for the reply.  Its not that I get just the Generic Connection, its the fact that clicking on the drop down tab of the Connection header ( to get to the various connections ) that it crashes.  My PC is certainly good enough - I7 6800K with 32Gb RAM and a 4GB graphics card.  Its when I click that little down arrow Revit keeps crashing.  Have managed to get to the actual connections maybe twice in ten goes, hence the few connections I have been able to generate on my frame.  So, in the off chance it might work next time, what connection should I use to join the I beam to the columns?

There must surely be a fix too, to my `crashing` problem?

Check to make sure your PC doesn't have an Intel Graphics Card running at the same time as your dedicated....  Windows tries to switch graphic cards for different purposes and Revit doesn't like that.  It needs to be the dedicated card no matter what.

Just looked in Device Manage and can only see NVIDIA Quadro M2000 under Display Adpaters.  Can't see it under any of the other headings either, unless I'm looking in the wrong place?

Thanks.  I was more meaning what connection from the Revit standard structural connections tab.  Just need to show a connection for my lecturer.

I was just kidding Darren. Just use an L-Clip. Or, if you really want to impress your instructor and stand out - design your own structural fastener. Go for it!

While Revit cannot assign any OOTB connection between a HSS column and a WF beam, you can create your own as a family an place it manually.  The bolts need be long enough to penetrate the column so that you can tighten them on the other side.  Welding is another possibility.

Change the column to an I beam. Create the connection so that it fits your end beam, then change the column back to a hollow section. Connection will stay put and will be visible. That's probably the easiest thing to do. Make sure if you bolt to a hollow section to use lindapter hollo-bolts. This is the simple answer. If you really want to go for the proper engineering approach then you use like it was illustrated earlier: a stub(short beam section) fully prewelded to the hollow section column with an end plate welded at the free end. Then you have your beam that needs to be connected to it and use an end splice(front plate splice) between the beam and the stub. For what you are doing, is probably too much hassle so just stick with the initial advice: change column to i beam , generate connection, change column back to hollow section.

Kind regards,

Ben
