Concrete Diaphragm - Grad Engineer Mistake

[@bengthebrazilianengineerinAus]

Obs.: The suspended slab can absorb bending moment and reduce deflections depending on its rigidity. You can create a portal frame system with the slab as long as you design it to work as such. The point I’m trying to make is that the forces will not disappear. The sum of the horizontal reactions will still be the same with or without the slab and if your columns are not stiff enough, the structure may still excessively deflect. Hope this clarifies :)

Nicely, shortley explained an IMPORTANT topic in structrul engineering, well done!

[@bengthebrazilianengineerinAus]

Thanks Musab :)

From a BEng in the US, muito bom ver mais brasileiros ajudando a comunidade da engenharia estrutural! Great explanation! Keep up the good work!

[@bengthebrazilianengineerinAus]

Valeu meu brother. Muito bom seu canal tbm. Abraco

[@rabibrahman5990]

Awesome demonstration.

[@bengthebrazilianengineerinAus]

Thanks Rabib

[@ahmedferdous2433]

Very very very helpful..splendid

[@anton9004]

Great demo. Thanks!

onz thing is that a diaphragm (concrete slab) is a horizontal bracing, so it is a bracing. however, the overall structure misses vertical bracing. just to clarify, it does not mean that the slab (or diaphram) is not acting as bracing.

[@bengthebrazilianengineerinAus]

yes. Thanks for the clear explanation :) The point of the video was more to remind engineers to follow the load paths and transfer the loads from the horizontal bracing to the vertical bracing and foundation. Just basic stuff that we miss when we're starting in the profession. Cheers

very interesting and very clear explanation sir. thank you.

[@bengthebrazilianengineerinAus]

Thanks Sam

[@thualfiqar87]

Well said

[@bengthebrazilianengineerinAus]

thanks mate

[@brianmugabi7516]

Great content! Thanks to technology (software) that can help us quickly analyze and solve problems in addition to our prior knowledge.

[@bengthebrazilianengineerinAus]

God bless technology :D

Have you set self-weight of slab equal zero for this illustration?

[@bengthebrazilianengineerinAus]

I did :)

[@PawanKumar-xr4qm]

I am bit doubtful about the last illustration of wall modelled. Becoz no diaphragm can be compared with flexible diagram and flexibile diagram distribute the forces equally to the colums opposite of walls must have higher deflection as their stiffness is less kzbin.info5P0WbSV2kcc?si=ei4nuTO1OVM9YsrG
