I recently posted about what types of software others here use for connection design and got many different responses. Many people said they still use hand calcs for connection design. To those people, I was wondering what are some good materials and places to look to start learning connection design and what type of design checks I should be doing for that connection (this includes simple shear connections, moment connections, brace connections, etc.,). I am a new EIT and I am having trouble understanding the different limit states like beam web yield, beam web rupture, plate yield, plate rupture, web buckling, etc. Like I do not know what some of these limits states exactly are and how they apply to the connection. Furthermore, I do not intuitively know which limit states should I be checking for this type of connection. For example, I don't know intuitively the limits states to check for a shear tab or a extended end plate connection. I am in Canada and the CISC has very limited info on connection design. So I was wondering, what are some good reference materials to learn this stuff?

What are some good references for connection design for a new EIT? 2

AISC has many design guides that cover connection designs. These design guides are free to access if you are a member of AISC.
To highlight a few of interest:
There are also connection designs in the AISC design examples which are free to access online which include a lot of simple shear connections. See below.
I can't speak much to design references with the Canadian codes.
To highlight a few of interest:
AISC DG1: Base Plate and Anchor Rods
AISC DG21: Welded Connections
AISC DG24: HSS Connections
AISC DG29: Vert Bracing Connections
AISC DG39: End Plate Moment Connections
There are also connection designs in the AISC design examples which are free to access online which include a lot of simple shear connections. See below.
I can't speak much to design references with the Canadian codes.
Similarly to the AISC documents, across the water in Europe there are numerous good resources (with worked examples):

Irrespective of code checking, the principles are largely all very similar. So worth a look!

Infact - with reference to IdeaStatica....
I often find the user manual for software a great place for equations and calculation references.
Here is the link to Canadian code checks:

There's currently an on-going night school by AISC on fundamentals of connection design. You might want to check it if you can afford it (you can check if your office reimburses you for such activities)
What's your objective? Just curiosity? Solo delegated engineer work? In house (west coast desig practice)?
the global sense:
Modern Steel Construction,
Anything by Kloiber, Thornton, Muir, or that other guy at LeJeune (ETA: Victor Shneur) with the tips on connection costs. It's a deep subject but study yields rewards. Your various AISC convention recordings, transfer loads, etc.
ETA:
I don't have an FAQ on connection design, but Practical Considerations for Steel Construction in the AISC forum FAQ has links two two Shneur articles (added just now) on connection design. These are general advice articles.

That's unfortunate. AISC has a YouTube channel that you can refer to
There are so many books out there but starting from a generic text book sounds ideal then you can get into connection textbook
The kindle version goes for $3
These are old (4 years ago) but still a great start and then you can refer to any steel textbook. Once you get the basics, other materials will be easy to understand.

Steel Tube Institute has loads of resources on HSS connection design, including articles with design examples, design manuals with more design examples, HSS Connex to determine minimum wall thickness at connections, spreadsheet design tools for professional members, etc. You can start with this resources page, and if you have specific questions, you can use the "Contact Us" page.
The pitfall of HSS connection design is usually wall thickness, if the EOR wasn't paying attention to the preliminary checks and went with 3/16" or thinner walls you can have difficulties (I'm referring broadly to truss style connections).
There's an STI seminar on September 18th (I think) on a three story building that is free....

To add to lex, knife plate connections from beams to HSS have design checks that do not depend on load (refers to CIDECT DG3) which are checked in RISA Connection. I'm not sure if these are referenced in the Canadian or American codes or if they are just something RISA decided to add due to research. Either way, 3/8" knife plates just don't pass the check for anything smaller than a 8.5mm thickness for 350MPa HSS and 300MPa plate, or 7.37mm for 350MPa HSS and plate.
Funnily enough, CIDECT's website does not allow you to download any design guides, all activity is on hold and has been that way for quite some time now.

Steel Tube Institute has a free tool to verify that your specified HSS wall thickness is adequate. It's called HSS Connex, link below.
And yes, there is a free webinar on September 18th, comparing the use of HSS to wide flange for a five story office building. The line up of webinars for the rest of the year is shown here:
