One way and Two way slabs - When to model slab as membrane and when to model as shell thin

[@nicolasmarie4398]

Hi. Thanks for the video. There are situation where we have to put the Longer Bar as B1 and the Shorter Bar as Distribution/B2 bars for example if there is a cantilever adjoined to the longer direction. I will greatly appreciate if you can talk more about this? Thanks.

B1 need not be always short even in normal slabs. It is dependent on many things. In site it is not practical in a large building as adjacent slabs may have different orientation.
For your cantilever question, see if this video has any info ruclips.net/video/8GPx8ZIrZCM/видео.htmlsi=9LUZqg4tTEkJIciA

Thank you sir

Always worth watching your videos sir.
Full on knowlegede and your unique way of teaching makes hard things very simple to understand.

Thanks for your words

Very informative loved it.

thanks for the comment 🙂

[@manuswaruprajsekar1775]

Very well explained sir. Thank u for your effort..

[@CIVILERABangalore]

:-) Nice to know you liked it

[@hcStructuralDesigns]

Yes, sir I have experienced this in cype cad.
In FEM design, one way and two way slab won't work.
Wherever the more moments we provide more steel on that direction.
Thank for the video sir.
You explained the same thing here in this video.

[@CIVILERABangalore]

but why? why 1 way and 2 way dont work? It works but only that it is approximate rule of thumb
The reality is based on stiffness which is captured in shell analysis

[@hcStructuralDesigns]

@@CIVILERABangalore yes sir.
In fem design of slab there is possibility of getting more moment in longer direction of slab.

[@CIVILERABangalore]

@@hcStructuralDesigns Thats the reality. stiffness decides the flow.

Sir really your teaching is excellent 👏please I need more more videos sir....🙏🙏 Thank you so much sir.....

[@CIVILERABangalore]

Nice to see your comment Ravishankar. Nice to know you learnt from it. More videos will come but you can choose to enroll for my flagship course too if you have not 🙂

[@hcStructuralDesigns]

Sir there are two methods for detailing for slabs, one is crank bar method and another one cut piece method.
Can explain two methods in detail.
Which method is easy and economical???

[@CIVILERABangalore]

Its all covered in the courses. Is it possible to achieve detailing by cranking if the bottom rebars and top rebars are considerably diffferent? cranking works well when the slabs are small and spacings are all uniform

[@zuberibrahimsultan8771]

Which model is more accurate, membrane or thin shell ???

[@CIVILERABangalore]

shell thin will be.

[@zuberibrahimsultan8771]

@@CIVILERABangalore could you tell me why ???

[@CIVILERABangalore]

@@zuberibrahimsultan8771 Should be in the video. Membrane will replicate Yield line theory behavior and shells would do stiffness based
