One of the best videos/sites on Stiffness matrix here on KZbin

[@DCBAonline]

Andrew Jeffrey thank you so much, feels good to read such comments.

[@andrewcjeffrey]

I am currently doing a postgrad course in Stability and Dynamics, and after watching at least 6 videos on KZbin, yours is the only one that makes sense - you've made this topic so very easy to understand! I would like to request that you do some worked examples so that we can consolidate our understanding. Also, can you do a video on trusses, using the Direct Stiffness method? Thanks in advance.

[@DCBAonline]

Andrew Jeffrey sure i would definitely look into providing more examples and solutions, actually even I'm doing my post graduation in Structural Engineering so these days im having a hard time managing the videos though i will definitely pay heed to your request, thank you.

[@andrewcjeffrey]

Thank you.

[@saureennaik1603]

great work buddy, clear and precise. Pls do more of such videos

[@sidahuja2851]

Thank u so much sir for this fully conceptual vdo on stiffness matrix...i hv watched many vdos but yet had confusions about direction. But now after watching ur vdo all confusions are cleared . A big thank u.... Pls make more vdos and continue ur service ....

Good one

In 1:52, right hand rotated towards you but your red arrow goes in the opposite direction. Should the arrow flipped as the four grey arrows? Am i right?

[@Inspirational_Homes]

sir please make more conceptual videos thanks

[@kashmirtheheavenonearth6410]

Luv u bro

[@jaffarkhan4487]

How to calculate the reaction values?

[@purplepenguin91]

I have a question, in the previous video the direction of angular rotations are different, is there a reason why they have this configuration versus the other one? Also how did you go about choosing the direction for theta B for the matrix? I had used the same direction theta B had in the previous video and didnt quite work out. Btw, love your content

[@DCBAonline]

Can you please mention the timestamp where you have doubt and also possibly the link of previous video and timestamp which you mentioned. So it would be better for me to solve doubt.

[@purplepenguin91]

@@DCBAonline I was actually able to figure it out! There was an assumed positive direction for the angular rotations at A and B, but I greatly appreciate the prompt response :)

HOW DO WE FIND STIFFNESS MATRIX IF THE BEAM ELEMENT IS INCLINED LIKE TRUSS

[@DCBAonline]

for an inclined beam element the stiffness elements include sine and cosine terms and they need to be derived before writing it in matrix form.

[@abhinayakula1644]

HOW DO WE DERIVE THE SINE AND COS MATRIX

[@DCBAonline]

Abhinay akula by resolving the force components

[@abhinayakula1644]

JUST LIKE TRUSS ELEMENTS??

[@DCBAonline]

Abhinay akula you need to resolve the forces and then find the rotations and deflections done due to those forces and then form the stiffness matrix
