Approximate Analysis of Frame with Gravity Loads Example 1 (1/2) - Structural Analysis
HTML-код
- Опубликовано: 9 сен 2024
- This is an example problem for approximate analysis of a statically indeterminate frame with gravity loads. The approximation is based on estimating the inflection points in the girders of the frame.
Part 1: Estimating the location of inflection points, detailed analysis of a girder. Drawing approximate shear and moment diagrams of the girder.
Part 2: Quick analysis of girder and shear and moment diagram. Determining the support reactions of the frame, approximately.
After 6 long years, I have graduated from the University of Queensland (located in Brisbane, Australia) with a Bachelor of Civil Engineering (Honours) and Bachelor of Commerce. If it wasn't for structurefree's amazing videos walking through solutions to many different structural analysis problems, I don't know whether I would have made it. THANK YOU for your help over the years, it has not only helped me, but many other aspiring engineers!
Mate, I'm at UQ as well and these videos are just so unreal!
I love this guy! It’s rare to get this solid of an engineering tutorial that is clear and fun to watch. love the energy!
I got an A for my structural analysis thanks to this guy.
Keep it up, structure freeeeee chuka chuka learninggggg 💙
Structure freeee Chukah Chuckahhh.. Awesome video dude. Thaknks
+looloolalaable awww yeahhhh, welcome back....
I've used loads of youtube tutorials for classes but this is definitely the first one ill comment on. EXTREMELY HELPFUL THANK YOU
also the only one I could find on portal method using vertical forces
Never been bored in your videos
Man please do some videos on portal frames and trusses. Solve some complex problems. This channel is amazing! 👌
Extremely helpful. Thank you for that. It would be very helpful if you have added the lateral loads (wind loads for instance) in the calculation. Looking forward to that.
Hey structurefree, could you do a video on the stiffness method? Thanks, love the videos! I’m doing very well in structural analysis with your help!
Can u help solve a question having both gravity and lateral load by portal frame method
I adore your intro!! So cute! 😆
Can we make an example for a frame analysis with cross method?
Which tools you used to write ? please tell hardware and software too.
Hi! How did you derived the moment at the fix-fix support beam wL^2/12 at video time 2:29 ? Hope I could get a response. It would really help. Thanks!
If we "assume" the beam fixed from both sides with this type of load, then the moment at the support is wl2/2
Search for fixed end moment and you will get it
I feel that i learnt.... cool!
wonder will it be more conservative to assume it as simple support or fixed support. Thanks!
boom! +structurefree please add example on tributary area load calculation.
Is this realiable to check with some software results of column end moments without doing a moment distribution method?
How to draw sfd and bmd for columns? Love your videos.
Where is part 2?
you're a god.
Dear Why 0.1L ?
regards,
+Cengiz Ipek some point from 0 to 0.21l. it's approximation
Dear MrGeiser :) Thank you for your reply
why don't we use 0.21L instead of 0.1L?
for average value ,Thats why (.21+0)/2=.1
pl z dont make stupid sounds sir, your explanation is awesome , so much helpful, but when making stupid sounds sometimes our attention is goings little bit out of the lesson.
I didn't get anything but awesome
just when i thought i finally understood.. lost it again
Marry me dude.....u're god.
