Moment Distribution Method Example 1 (1/2) - Structural Analysis
HTML-код
- Опубликовано: 9 сен 2024
- Introductory example problem applying the moment distribution method on a statically indeterminate beam. This is a good place to start if you have never applied the moment distribution method for structural analysis.
Part 1 demonstrates the application of the moment distribution method in detail.
Part 2 shows you how to draw shear and moment diagrams once you have determined the member end moments.
I can't believe how easier it is for the newer generations of engineering students to learn these concepts. When I was in University in the late 80s we had very limited (dial-up !!) Internet and certainly no RUclips. We had to haul our a%% in the campus library, dig through pages and pages of other books (in addition to our textbooks) , find material that was better explained than our prof would explain, find coins to insert in the photocopying machines (most engineering textbooks were 4" thick and hence heavy!) and photocopy relevant material. Now one can search 24/7 online to find solved examples that are well explained (such as structurefree does!).......
Well done sir !!
Then again, generations before mine used slide rules to design skyscrapers, so I shouldn't be complaining.
To those of you that are studying engineering, it is a rough, tough and long road but well worth it. Tough it out; work and study hard and at the end it will pay off.
Apologies for the long post. Keep up the great work you do 'structurefree" !!
To be or not to be.... that is the question
so true man. I acknowledge how super lucky i am. Don't think i could've been an engineer if it weren't for youtube. RUclips has taught me everything for maths, I taught myself calculus watching youtube videos, all the way from even before precalc. you're very right, we have it much much easier. and i'm so thankful for it, because it gives me the opportunity to become actually try and become an engineer whereas otherwise the odds would've been stacked against me, such as in your times. It's much easier now but it's still very hard nonetheless.
The good thing with you guys is that you learnt more by going thru that
@@TheMrgoodmanners 100% true
Yes we use RUclips to learn.. But we still weak..
hours of searching making you never forget it, and you learn much more by searching.
Dood, you have no idea how popular you are! The amount of people you are helping is crazy! Thanks for making your mark in engineering education!
+Eugene Smith Thank you for the kind words and your support!
Someone give this guy a medal
bling, bling.
thanks for the kind words and comment about units. I try to do both sets of units since I teach in the U.S. and the structural design codes are primarily in the FPS system with conversions to SI.
I wanted to extend a personal thank you for this video. I'm studying for the October PE exam and a question on a practice exam asked to solve for a reaction using this method. Never heard of it, let alone used it. This video saved me what would have been days maybe weeks worth of time trying to study and understand this method from a book or online source that probably would have taken me days to find in the first place. Absolutely brilliantly explained, clear, concise, excellently done!

You just did a better job of teaching me this than my professor did with 3 hours of class time and 6 homework problems. Thank you sir!
This is the best distribution method video on youtube; i have ever seen!
OMG...., you just don't know how you are amazingly supportive comrade, you deserve lots of gratitudes for real, from Tanzania may God bless you here on Earth and in heaven!
You are the GOAT of Civil Engineering!! I can't tell you how many times you saved my grades, I just love your work!!! God bless you!

I'll be taking my final in this course next week, and it looks like I'm home free. I couldn't have passed this class without your videos.
I hope your exam goes well and you end up doing better than passing!!
Watching this in 2019, excellent explanation!
This is the best explanation I’ve come across on this topic. Thank you so much
Thank you for the kind words!
Best explanation i have seen so far

My mother language is not english.. And I congratulate you how you can articulate very well.. Good lesson.. If you make more videos about Method of Hardy Cross.. We will apreciate. Thanks
Thank you so much for all the videos. I'm taking the FE exam after been out of school for 5 years, and all this info is very helpful. You're the man..
Without your videos i can fail my exams and with your videos i will not fail but also i will get a good mark, thanks very much!
You are the apple to my structure analysis
This video still kicks ass 9 yrs later
Thank you so much. Finally, I've got it . It's very useful before my examination. Simple description and understand easily.

k=3EI/L is used when the beam has a pin/roller on the free end or where the beam structure terminates. In this example, the roller is supporting the continuous beam and a moment can be carried across the beam at the support. See the moment distribution method example 3 video, it has a beam segment that uses k=3EI/L.
Amazing work. The cleanest and videos explaining engineering concepts and processes. This helped me a ton. Thanks, thanks.
Thank you! Very very useful. I was lost until I found this...
You are my best teacher ever!!!! You are amazing , I love you
truly thankful ur the best im goooona pass the exam tmorw :)
Sir, Thanks for all your videos.
Bro!!! I just wanna say thank you for this! 😊
Life saver. Thank you my man, thank you.
You are the best bro, you have help me pass a lot of exams. Greetings

Bro, I have understood things I havent been able to understand since year one in 15 minutes
Wow, best 15 minutes ever?!
@@structurefree The best ever
Very good and funny videos bring a great sense of entertainment!
Please add an example for a structure with an overhang. Very interesting and quick review thanks
very helpfull... thnk god i found your channl
Hey bro, not sure if you have a video on the stiffness method but if you don't, you should definitely make one! Love the channel, keep up the great work!

Oh man you're so helpful,thank you.
Im your biggest fan of your brain in the arab world lol
U really help me
Plz pray for me tomorrow is my first midterm exam in this subject 😭
God bless you.
Amen.
Deadpool is that you?
Bruh my english is my second language and I understand you
Thank you🎉
Bruh...structural analysis for all!
Thank you, sir! You've helped me to understand it easier
I LOVE YOUR VIDEOS
+ANSAH NANA BENYI thank you. #loveincapitalletters
thank you so much ! very helpful especially when you have a terrible professor!
Thank you sir! Please also include a video about moment distribution method on frames with sidesway.
When you calculate (FEM)AB, why you use w in (k/ft) and l^2 in inch?
Thank you for these amazing videos! I only wish I would have found them a year ago.
Fo sho.
A very detailed introductory example applying the moment distribution method. This is a good place to start if you have not seen the mdm method applied or need a refresher.
I thought you said MDMA, if you know what i mean lmao.
Thanks Soo much for clearing this up for me it was really bothering me with the carry over

Hey structure free. I love your videos it helps me a lot in civil. However could you please you do your units in the metric system. I think most countries use those units now and are more universally adopted
thanks so much buddy..helps a lot...done beautifully
I'm not sure if it was discussed in previous videos - how do we determine the K value to begin with?

Thanks for the lecture, the only problem for me is to convert KN/m to K/ft and in^4 to mm^4 for, we use (m) in north Europe.
sir it was very helpful ,application oriented please upload matrix method of truss and frame analysis by matrix method please upload
thanks for the help i have a small dought thanks man
Really Great work keep it up
Could you please Attach the solution steps as a PDF or maybe any other format that can be used as a hard copy Reference . Because really i haven`t seen any one illustrating the Moment.D.Method in that simple easy to understand way . and thanks again you are really great
Hey mate. Your videos really help all of us. They are probably the only thing that ensures we pass uni. And by "we", I mean the entire cohort of engineers every year. Appreciate it.
We just don't understand, in this instance, how you got the zeros in the purple line at joint B. Could you please clarify?
If you add the moments on each side of the joint B ( 52.083-3.456=48.627 and -40-8.627=-48.627) are equal. that means are balanced and you don't need to apply again the distribution factor. The iteration process finish when you get moment equilibrium at interior supports.
better later than never :)
@@marlam5478 Okay, can you still try to reexplain this? I don't understand. My professor kept doing the iterations until the distributions were negligible and small. What happens if you have seven iterations, do you have to keep adding up both sides of the joint til you figure out if they are even?
It's like hearing jesse pinkman discuss theory of structures
you are the best
you are very helpful...
Excellent!
Thank you so much for this! This is really helpful
good job bro. thank you so much.
Thank you
very nice explanation. Thank you. Btw, what software are you using for the writing stuff?
TERIMAKASIH SANGAT BERMANFAAT DAN MEMBANTU !!!!
Hi Structure:
I was wondering why your Carry Over for both parts of Joint B are 0 after 1 iteration? Im trying to teach myself this method and I cant figure this part out.
Thankyou !!!
too helpful .. thank u very much sir .....
Professor, please lets see a worked moment distribution solution to a "cube", "cube beside cube", "cube on cube", and larger number of cubes (rooms that is). a cube is four columns joined with beams above and below (or foundation on a ground floor). a roof can be an "area" of spread out load (like reinforced concrete). i have been surprised with so many books stop after beam, column and a 2d portal of two columns and a beam on top; and then plenty books dive into matrices.
Structurefree in the house!
Is the carry over factor always 0.5? How do you know what value to use for the carry over factor? Thanks for the great vid!
the best thing is that reading the replies of structurefree ...who else enjoying it
Word. I enjoy it too.
hope you would also post example using three moment equation
Hello..that was agood jop thanks for sharing 'can u do an example for redistribution moment!
my hero...
good work.....
Can you please make this video with metric units ? These imperial units are a bit confusing, thanks. And great job

sir , while calculating member stiffness how did you get 12 at the denominator.
ruclips.net/video/rI9qaseL1rs/видео.html
thanks alot structurefree , but where is BMD? The second part is from other question?
thank you! much help! much wow
mo wo-wizzle.
Where's the drawing for shear and moment diagram?
What would be DFab if there were a pin joint in A?
man can you do a video about frame using MDM
In the last row of the table in joint BA and BC part how did the values become zero?
Thanks alot man
BAM!!! Thanks!!
THANKS SO MUCH.
YOU'RE WELCOME.
Thanks for the awesome vids :)
But for the member stiffness shouldn't it be k=3EI/L, because it's a cantilever to pin/roller? I'm confused.
Far end is fix=) 4EI/L
Far end is pinned=) 3EI/L
