Staircase Load Calculation | How to Calculate Stair UDL Load | Load Transfer from Stair to Beam

Usually Most of the Structural Engineers Won't Model Stair in their Projects on Etabs or Staad Pro, Instead they Calculate the Stair Load as UDL and Apply that Load on Corresponding Beams.. In this Video I have discussed about the Stair Load calculation and Load Transfer as UDL from Stair to Beam..
If U have any Suggestions on Improvization of this Channel, Kindly tell me on any of the following social media's..

very smoothly explained please explain more structural component design as continuous beam ,column , slab ,bridge etc. design in this way
again thanks for explain

[@PraveenKumar-kg9ql]

Super video for quick understanding with animation but here 3 mistakes done....
1. Landing Load not consider at MID SPAN BEAM o fcourse not required at Plinth level because it is not present in you 3D model.
2. You have added 23.90 Kn/m on Mid Span Beams but it is 11.95 Kn/m only because you have calculated for one beam it is 11.95 Kn/m beside of that another beam is connected so if you add 23.90 on Mid Span Beam (23.90+23.90 =47.8 Kn/m UDL is applying) therefor we have to add 11.95 Kn/m only.
3. At plinth level and roof level you have added 11.95 Kn/m on whole length but here we have to add that load only half distance which means up to width of the Stair Case only and for remaining part it is not necessary of course when detailing small changes in shear reinforcement we can design for whole length for loading 11.95 KN/m.

[@deepapanneerselvam4618]

Very good attempt but How can you multiply with 1/cos theta instead of multiplying with cos theta...?
why are multiplying with projected length of the slab .....?instead of multiplying with Inclined length of the waist slab.....

Good explanation of transferring staircase loads on beams considering udl only but is 875 considers both point load and udl in staircase design

[@RakshitParazulee73]

Beautifully explained! Keep on sharing your knowledge.

[@maheshg5516]

Please make like this more videos, clearing load transfer concepts too helpful

[@zorro20010]

gravity load applied on the waist slab is always vertical directed towarrds th ground wether its Live load or dead load and it has to be inclined to make it normal to th waist slab
therefore th normal load on th waist slab wil b 9.40xcos(31dg) =8.06kN / sq.m for wich th waist slab is to be designed

[@debasishgoswami9291]

Thank you sir, it has cleared my confusion today.

[@ashishvardekar1746]

This is so helpful sir..

[@maniraja5711]

good work bro..!!

[@ramprasaththangavinayagam2516]

Great explanation. Engineer

[@devkartik]

Thank you sooo much for explaining that inclined load part!

[@zorro20010]

th inclined part was wrong
gravity load applied on the waist slab is always vertical directed towarrds th ground wether its Live load or dead load and it has to be inclined to make it normal to th waist slab
therefore th normal load on th waist slab wil b 9.40xcos(31dg) =8.06kN / sq.m for wich th waist slab is to be designed

[@zorro20010]

th remaining is good explanation of load transfer to beams

[@omarabdullah9969]

thank you....i understood very clearly

[@indramlimbu6886]

Very informative...keep up

[@abrananth]

Usefull thank u

[@tgmalunas2350]

pls explain where did the values of brick steps calculation came from, I dont get it

[@billygratia8902]

very helpfulll thanks a lot

[@jeevan10]

Thank you Sir...🙏🙏🙏🙏

[@MrLivekp]

Very thanks

[@nareshojha34]

Can you share design and load calculation excel sheets

[@soneemaharjan1719]

Sir plz upload video for open well staircase

[@ronakvagadiya8044]

Sir plinth/roof beam Carriers U.D.L. load in whole beam or just at a portion of stair width......?

[@civilconst]

Its carries for the portion of staircase width only.

[@angelofigueroa1305]

The video is good but the values appeared out of nowhere... not beginner-friendly

[@wyong6198]

Can u provide the L shape staircase calculation? Tq

[@Noone-qx4dv]

Hi, is this applicable to its deadload as well? coz u included the Liveload on the table in 0:50 Thank you!

[@zorro20010]

gravity load applied on the waist slab is always vertical directed towarrds th ground wether its Live load or dead load and it has to be inclined to make it normal to th waist slab
therefore th normal load on th waist slab wil b 9.40xcos(31dg) =8.06kN / sq.m for wich th waist slab is to be designed

[@zorro20010]

9.40kN/sq.m x sin (31) = 4.84kN/sq.m is the tensile stress on th waist slab section

[@dmah5183]

Very good. But some of the ideo are out of focus.

[@moutasemabdulrahman1194]

Doesn't the load taken on stairs have to be vertical ? since ETABS takes only vertical or horizontal loads

[@ronakvagadiya8044]

Sir, can u Please make a video for c-shape of stair which is having z beam..?

[@erkajamohideen]

Sure bro

[@ronakvagadiya8044]

Can I sir got u r mail I'd..?

[@mirestoration9154]

Sir you did not calculate the load on landing.
Can you please clarify this

[@sagardas4888]

I don't understand sir (0.5)

[@ishapatel7823]

0.5 is 1/2 X RISE X BRICK DENSITY. i.e 1/2 X BASE X HT X Density, We consider base as 1m.

[@laxmiraj5716]

@@ishapatel7823 if u take base as 1m then height will get changed.
