Nicely explained sir, really awsome....

[@CivilBlackBox]

Thanks for liking

[@prudhvi5263]

I have a query related to STAAD pro analysis, will we give FRP material as a surface material to the concrete beam ???

[@CivilBlackBox]

Can you please drop me an email at [e-mail] with a detailed issue you are facing?

[@mahendraaandkaanchanpatil1489]

Hello sir you are not uploading new content Sir pls hlp with master slave , diaphrame release moments torsion aspects You are the best & clarity is very high

[@CivilBlackBox]

I have explained all these concepts in my Course "Structural Consultancy Blackbox". If you want to go deep, you can join the course. www.civilblackbox.com/structural-consultancy-blackbox

In secondary beams creation moment release at ends of secondary beams should also be shown. I was watching this because i have released Moments Mx My Mz at ends of secondary beams of a multi storey building. But after i run that for analysis it gives too many warnings at those points that release of moments have caused After making those ends of Secondary Beams Rigid instead of released i found that those warnings disappear but that is not good modelling. Should we care about removing those warnings

[@antoniosingh9758]

Sir I followed this tutorial, however after run analysis, there were many errors saying that the structure is disjointed and there were many Unstable warnings. I tried adding member end releases to connect the secondary beams to primary beams and the problem didnt show up in output file. However, now none of my loads (dead load and live load) are showing up over any of the beams where there are member end releases. What should I do ?

[@CivilBlackBox]

Firstly, you don't need to release moments. That is not how RCC works, assuming that you are working with an RCC frame. Secondly, I would suggest creating a new file and starting all over again. I hope the errors would go away. If they don't you can share the STAAD file on the FB group and I will take a look at it.

Sir secondary beam action for fixed beam or simply supported beam

[@CivilBlackBox]

Could you please elaborate your question a little more!

[@mystogan1186]

Why secondary beam is adopted? How much is the maximum spacing between column inorder to adopt sec beam?

[@dpat7566]

Very nicely explained . Thank you.

[@CivilBlackBox]

Glad it was helpful!

[@dpat7566]

How do you achieve same floor beam top of steel elevation when steel beams of different depths are used ?

[@jipjiptv566]

how to create a dummy beam? for my cantilever slab without beam

[@positivevibes4265]

Sir why you didn't release the moment at secondary beams??

[@weindians1813]

Very good information

[@CivilBlackBox]

Glad you liked it.

[@mahendraaandkaanchanpatil1489]

sir if a float column is taken from beam end shall that end be hinged for parent & support beam?

[@CivilBlackBox]

I will ask you a question to answer you. How would you provide a hinge in RCC structure? If the answer is you can't, then I you probably have the answer to your question as well. When it comes to RCC structures, a hinged joint (or moment release at a joint) is not feasible from the practical point of view. The story is different in steel structures of course. So the take away is simply this. Whatever you can create on site during execution of work is the same thing that you should be considering while modeling. Hope that helps.

[@mahendraaandkaanchanpatil1489]

Sir in the design pile foundations are considered to carry zero moments We create hinge inside the cap by criss cross of pile bars and firmly arresting finally in to the cap mesh Similarly any secondary beam is transmitting end shear force to main beam as a simply supported behaviour is most likely occurring Please comment on my statements as what you are saying is although reality may involve indeterminacy and complex extensive calculations leading to very high reinforcement

Very useful bro thanks

[@mahendraaandkaanchanpatil1489]

I have sir a counter balance supported cantileaver beam & the to steel must go uncut inside frm Cant to main beam how to model such beam Further Can you do a video on bracket beam supporting a five story load

[@ahmedferdous2433]

Sir usually we release the member at a secondary beam connection. Can u pls explain why?

[@CivilBlackBox]

That is a flawed practice. Releasing moments means there is a pinned joint which is usually not the case in RCC beam to beam connection. You should never release moments in secondary beams if you wish to simulate the true behaviour of structure for analysis.

[@sudarshannikam5243]

Sir is it necessary to merge beam to primary after inserting secondary beam before analysis ? Because after inserting node in primary beam it is divided into some pieces or numbers of beams.And they are gotten different beam no. What will be the correct method ? Either merged primary beam or leave it as splited beam before analyzing.

[@CivilBlackBox]

Split of a beam does not change the analysis. The only thing that changes is that you will have to look at the parts individually to find the reinforcement etc. As far as the analysis and mechanics is concerned, an additional node does nothing. Hope this helps.

[@beghuroba5326]

@@CivilBlackBox So we dont need define such as LZ, LX or something like that?

Very good, learn a lot of useful techniques. TQVM

Thanks Philip.

[@santhoshnageshwar8701]

Which movements are released for secondary beams.. Please share that also

[@CivilBlackBox]

Surely will.

[@rozza6068]

sir, can you please tell me if there's any tutorial video or suggest me a book to understand on when to provide secondary beams, purpose of s.beams and bar bending schedule of s.beams and loads and forces acting on the intersection of beams where there is no support? I've seen they have provided in case of long spacing of columns and in garages but i dont clearly get to know the load distributions on it and arrangement of reinforcements. thank you.

[@CivilBlackBox]

I will try and compile some resources for the same

[@zorro20010]

In staad modelling of RCC structures the beams and columns are provided from centre to centre Everything is c to center Wen beams are joined centre to center at corners there is no concrete at the corners because the beam is center to center This is also a reason for many errors to come To overcome this someone sugessts that v take a offset and extend that beam from center to the edge of th column What is your opinion to this Perhaps you wil adress this in one of your videos Besides i suggest that you make a comprehensive video about removing ERRORS from STAAD output and why they come in the first place Th floor plan beam slab layout of the of th first floor shud be checked for by using the various checks in the Tools menu That reduces much of th errors and warnings

[@vaidikshah9797]

The problem I am facing is when I create a beam it divides the primary beam in number of sections and it is problematic during load distribution

[@CivilBlackBox]

How so? You will just have to apply the loads on all the primary beam components which have been divided. Can you please share the issue that you face?

[@engabdirahim4090]

Why bentup provided in slab

[@CivilBlackBox]

Can you please elaborate your question?

[@TheAmanpro]

Sir what about plate? Will there be one plate connecting all four sides of primary beam or small plates inside secondary beams? Thank you

[@CivilBlackBox]

There has to be smaller plates inside the secondary beam. However, you can achieve the same effect by creating a larger plate and then using Mesh function.

[@RameshKumar-wz8by]

Please make a video on plate contours and using contours for plate design

[@CivilBlackBox]

Surely. Please support this channel by sharing it with your friends.

[@mukundkrishna5161]

sir It would've been better if you could have also explained about moment release in some directions and also how it structurally behaves when compared to Primary beams. But anyway thanks a lot sir.

[@CivilBlackBox]

Noted. I will try and make a detailed video on the same in the future.

I want design manual calculations beam with secondary beam was releasing and with out release the beam design main beam with manually

[@CivilBlackBox]

You should not release moments in Secondary Beams. This is a wrong practice which I see a lot of people doing. In RCC you cannot easily create a Pin Joint. And moment release is basically a way of telling STAAD that the joint is pinned.
