Deflection of Beams || Deflection Limits

This video shows the deflection of beams as per American concrete institute codes. ACI recommends to use deflection limits as L/360 for live load and L/240 for dead load. These are the two limits which we should consider while designing our beam and taking servicibility criteria.

Is this only applicable for simply supported beams?

[@mauricioguaman1366]

Excellent video.
In the cantiliver beam. Are the same limits? L/360 and L/240?.
Thanks!!!!

[@civilengineering94]

Yes they are

[@arizona111]

Excellent vid. You havea gift of explaining. Is the ACI formula for minimum standard across the board or is it only used in specific areas (bridges, houses, etc)?

[@nanjubaba1845]

i like ur teaching and ur voice Thanks

[@selvarajmurugan9996]

I saw one video that video they said dead load + live load = l/240. Live load = l/360 But it's different. Which is this correct one?

[@peporights7776]

U r correct

[@omikaps2684]

Nice video...Ur uploading very imp. Concept...ty very much

[@civilengineering94]

Thanks dear Omi

[@ayadjasim9911]

Good work ... thanks

الله يسعدك

[@danellbaptiste3084]

How do I know when to use the load factor of 1.6 for the live load. I was doing a similar problem and got it wrong because I considered the 1.6 load factor. Please help

[@civilengineering94]

It depends on which load combination you are using, be careful while selecting the load combination.

[@danellbaptiste3084]

Can you give a more specific situation.

[@basimalbasim6074]

Beam for pedestrian bridge L/? ... thanks

[@emadgasser996]

You have to used I effective

[@mariosamardzic7751]

Good explanation ... thanks

[@C901-r8i]

why do you multiply the length by 12? Also, where from the 5/384?

[@reddevilian]

He is multiplying by 12 to convert to inches; 5/384 comes the deflection formula 5/384xWL/EI

[@civilideas1925]

👍🏻

[@tamim1089]

Please Mention the code number of ACI..
L/360 (LL)
L/240 (DL)

[@omikaps2684]

I think there is one correction... in the y max formula there is i effective instead of only i

[@S.B.Diyodkar6896]

very good knowledge 🌻🌹🌷👛💦❄

[@civilengineering94]

Many many thanks

[@sheikhkais4140]

So great sir g

[@civilengineering94]

Thanks dear Kais

[@mdahmed9336]

Thx sir

[@brentbarnhart5827]

What type of Beam? makes no sense? I-Beam, Square?, L, What about wall thickness?

[@brentbarnhart5827]

I studied this and used your equation, spent about 1 hour. You did a GREAT job, however at the very end I realized there were some things missing for what I needed to do. I was trying to estimate 4 x 4 square tube with 0.25 wall thickness. I'm not sure what the equation is for... but thank you.
