Thanks a lot man, your videos are always helpful, much appreciated.

Muchas gracias, amigo. Con lo que enseñaste pude corregir el problema

[@brayanccapaanton9220]

Thanks for your video, the explication is very well. You help me.

[@digantmehta7764]

Very helpful video. Also make video giving clarity about node diaphragm too. Thank you

thank you so much , it's exactly what i'm searching for
very very helpful

Thank you! I've been going through the same problem. Also help me on why and how to define mass source

Thank you very much, very helpful.

Thanks for this great video

[@firaselhajmoussa6612]

Thank you soooo much, you're amazing

[@civilEngineering1145]

Thanks 😊...if all floors are same,do we need to defin Diaphragm number like D1 D2 ....et
For each story?

thanks a lot...this problem suffered me a lot....now its solved...thanks

Glad it helped

[@jhengroup]

Thanks a lot. This has helped me to solve a nagging problem. Much obliged.

[@Decodebd]

Glad it helped!

[@jhengroup]

I also found out that you could right-click the landings and change the Diaphragm entry to None. This also achieves the same result but its a little tedious.

[@galaxypungyambam5462]

Thanks sir! u save my day :)

[@strange086]

Nice sharing bro..

[@junyanchen6434]

Hello,I have a question.Does the stair weight tranform to lateral force from the seismic ?

[@NTC]

Would the mass from mid landing be included in the diaphragm if you do that way?

[@abenzer1946]

God bless you!!!

Thank u so much for thiis

[@michaelloreantz]

Should diaphragms always be assigned to floors? If I am using response spectrum analysis as an example, I am able to run the case without diaphragm assignments, so at what occurence do I need them?

Thank you sir

[@dhananjoydevnath9419]

thank u sir for your video, that was really helpful, I have one question regarding the fact that how can we assign diaphragm if the slab is inclined??

[@Decodebd]

No. for inclined slab we should not assign diaphragm.

[@keeyangyialao1017]

Thanks brother ❤

Welcome

[@mathstube1802]

sir can you share when do we have to use diaphragm option? what is its purpose?? do we have to use this option in any type of RCC frame structures design...Need your help as i am new to Etabs.

[@amitsah726]

sir,i followed the same procedure but still the same warning is coming.is it because of the same slab i have used for both staiecase landing and the floor?

[@asmaanasr9394]

Thanks

[@Latif_Abdul1]

Any reference for Diapharam assignment for U shaped building...

[@2EleDiosSar]

really smart you are

[@Decodebd]

Thanks a lot.

[@pi_arjun]

sir, any difference between assigning joint--diaphragm and shell--diaphragm??

[@The26011980]

tkank you

[@ankithrv]

please upload video on application of nonuniform shell option in etabs

[@mohammadtayeban6723]

Thanks man, I owe my degree to India

[@Decodebd]

Welcome

[@amitsah726]

Your videos are really great but it can be more effective for learners if u could explain why particular steps are followed in etabs I mean explanation of steps with reason.Thanks!
Like if you also want the same!

[@Decodebd]

Noted with Thanks

[@maunikmevada9115]

Why diaphragm assign ??

[@2EleDiosSar]

Sir how can the mid landing be shelling. i didn't see it in 3d but a put joint diaphragm for stairs and shell diaphragm for floors!

[@Decodebd]

Mid landing there will be no diaphragm.

[@2EleDiosSar]

@@Decodebd I really apreciate your remark thanks from latino's world --- Peru

[@Decodebd]

​@@2EleDiosSar Most welcome :)

[@8dsongs594]

Diaphragm we should apply separate for each storey or just 1 by selecting all storey ...pls ... urgent

[@Decodebd]

Selecting Separate for each storey. One diaphragm is for one horizontal level.

[@8dsongs594]

@@Decodebd thanks...

[@ronnie9096]

Sir, what is the difference between joint diaphragm and shell diaphragm ?. Is it same ?

[@Decodebd]

Joint diaphragm is connection between joints, Shell diaphragm is connection between shell corners.

[@ronnie9096]

@@Decodebd for Ground floor where there is no shell, can we assign joint diaphragm and for the rest of the floor i.e 1st, 2nd and subsequent floor where there is shell can we assign shell diaphragm. Since to my understanding, diaphragm action is to resist and transfer lateral force. Correct me if I am wrong. Plz elaborate.

[@rachkless]

Diaphragms displacement's results on my work is errors, how to fix it

[@Decodebd]

Delete/remove diaphragms, then assign properly again.

[@rachkless]

@@Decodebd okay sir I'll try it. Thankyouuu

[@ankithrv]

p( xyz)= ax+by+cz+d. non uniform load equation

[@nemalavenkatesh]

what is slab & diaphragm, purpose?

[@Decodebd]

Purpose of diaphragm is to find out CG of area & lateral loads will be applied on that CG.

[@nemalavenkatesh]

@@Decodebd Sir, but i never checked or come across this diaphragm concept in Staad pro, so irrespective of the size of the building we have to consider the diaphragm in ETABS, right ?

[@Decodebd]

@@nemalavenkatesh Yes.

[@nemalavenkatesh]

@@Decodebd sir does diaphragms are used in etabs only or is there any physical structural element also provided in building practically also? Coz i had come across diaphragms as a structural element in bridges, so in buildings also we consider in the site?

[@Decodebd]

Diaphragms are used in other programs also. 2 approach of applying lateral loads. One is to apply loading in peripheral nodes of beam column joints (like loads on cladding). Another is to apply lateral loads on CG of every floor.

[@manikandank2089]

Sir in etabs 2019 version detailing preference option is not available.so how to put detailing details.

[@Decodebd]

You have to use CSI Details for Detailing.
