My professor told our class if we asked him if a frame is sway or non-sway, he would call us stupid so I never asked. This video helps so much and saves me the embarrassment thank you!
NON SWAY FRAME sir Reason is whatever the loadings ,whatever the moment of inertia of members ,whatever the lengths of columns but there exists horizontal fixed support.
Because different members in a structure may have different values of moment of inertia. If the value of moment of inertia of one member is twice or thrice of that of another member, then it must be denoted as 2I or 3I respectively.
Great video. However, if the horizontal beam is made of two parts and one side has a different stiffness than the other side then the frame may be a sway frame too?
If the columns are of same length, same eleastic properties and having same end supports... then if UDL is acting on whole beam of different length and different elastic properties, it is a NON-SWAY FRAME. Bhavikatti is right.
This is not the definition of a sway frame. Your examples are all standard rigid connection "non-sway" frames. Just because the frame sways does not define it is a "sway frame". Please google search the definition of a "sway frame" vs. a "non sway frame" used by structural engineers.

That's really sad, but I'm glad that my video was of help to you.
It was very helpful for me, your style of clearing all concepts with examples is really appreciable.
Thank you sir. easy to understand and also the examples helped to confirm that I understood it
Useful sir 👍
Superb 👍🏻
Such a nice video sir ❤
Thankyou!!!
You're welcome.
nice video helpful
OK everything clear but what about bracing frames. Bracing frames sway or non sway. Can you give nor example on 3d frames
❤😍
Thanks this is useful!!
You're welcome.
Perfect :)
NON SWAY FRAME sir
Reason is whatever the loadings ,whatever the moment of inertia of members ,whatever the lengths of columns but there exists horizontal fixed support.
Would a ladder inclined at 40 deg and vertical load midway through the span, rigidly fixed at both ends be a sway structure?
Moment of inertia is denoted by I . But Why is there moment of inertia is denoted by 2I 3I, please explain someone 😶😶

Hey, Rob. Thanks.
And to answer your question: yes.
Udl is acting on beam and has different (I ) then it is sway but in ss bhavikatti textbook has non-sway frame
