Rigorous moment connection design
Rigorous moment connection design
(OP)
Hi, I was just wondering what's a good way to do a complete, rigorous moment connection design, in say, a moment resisting frame, for example.
I am trying to do a hand calculation as I don't have access to connection design software packages at the moment. What kind of checks do I need to perform to complete the design? I haven't been able to find any good resources with worked examples but some buzzwords I've come across on the web are things like: "tension zone", "t-stubs", "compression check" etc.
Any summary of the checks I need to perform and the theory behind them would be fantastic or even a good resource to learn about it.
Regards,

RE: Rigorous moment connection design
That being said, the answer to this question depends entirely on the connection style. A bolted end plate connecting two W-shapes is going to be entirely different than a fully welded connection between two different sized HSS members, which is going to be different that a bolted flange plate style W-section moment connection.

I am designing to AS4100. I am looking at designing a typical bolted beam to column connection for a portal frame. The members are I-sections.

Thank you for the help Trenno and TLHS.
Oh, what you said TLHS, is precisely why I ask. This is more of a learning exercise so I can better understand the software when I go on to use it later in my career.
Cheers.

Bit of a pain to go through them all by hand, but once you have a good grasp of what's happening it will make using the software that much easier.
I know Spacegass recently integrated a steel connection module according to the publications from the ASI and it seems to be pretty user-friendly.

Yeah I don't mind going through the motions, however long it may be. I eventually want to make my own spreadsheet to solve some typical problems of this nature.
Yes, Spacegass is the structural package I use the most but I have not bought the connection design package as of yet.
