moment connection in structural members

[kaffy]

Hello guys,
I understand that if the beam being used is I beam/W beam then in order to achieve moment connection(fixed connection),
both web and flange of I/W beam needs to be connected & for shear connection (Pinned) I only need to attach the web.

As the structures I work with are not under heavy loading, Previous engineers used C channel, angle, HSS sometimes as beams.
If those are being used as beam, what are ways to achieve shear and moment connection?

Thank You

Not correct, you have to connect for both moment and shear... they are both different 'critters'.

For connecting beams and channels, for shear you can use clip angles, for moment and shear it's best to use end plates.

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

@Dik,

Sorry I do not understand. My question is :

As we commonly have S beams and whenever we have a moment connection, We use end plate connection. End plate is welded to beam(both flange and web of beam are welded to end plate). Now end plate is bolted/welded to column.

My question is If someone wants to use HSS/angle/c channel instead of S or other structural member. How do we make a moment connection?

Thank You

here are images of a few examples of connections using steel tubes:

The top left detail in kipfoots link is most common in these environs, else a plate welded to the HSS section to attach a bolted end plate is also common. HSS with end plate is common as well as C section is often connected with clip angles. An angle is often connected to a simple fin plate welded to the face of the HSS for small loads.
