Thanks a lot, this comment means a lot to me, keep watching and supporting

[@krishnaprasadm7318]

Sir,the lecture was very nice,in last step for calculating Tbd ,we have to take 60% increase for deformed bars .so it will be 1.6x1.2 for M20

[@somnathmukherjee5794]

Sir, the way you explain different topics in your videos is just great in one word.

Excellent teaching . Easy to understand the details of design procedure. Your teaching methodology is very useful to the teachers those who are handling this subject. sir, while desingning the beam for the residential buildings, it is considered as SSB of Fixed beam.kindly provide the details . thanking you.

Hello engineer..... I had read lot of books about design for footing then I found some thing is missing them I came across "pillai and Menon" after ramamuthram and I found ur teaching so easy and understandable with code provisions.....plz work on designing solutions ( being str.engg ) it helps me. ....to get old knowledge back.....plz show: Column, slab, mat,raft,sloped,can't.slab.....and more designs and plz refer books with code provisions......

Dear sir, For dead load you calculated, 25*1*0.175 = 4.375 kN/m2 I think the unit should be kN/m 25 kN/m3 x 1m x 0.175 m = kNm2/m3 = kN/m Please verify

sir,your teaching is very nice. But before your are going to do problems , explain theory part..PLEASE SIR!!!

[@structuralanalysisanddesign]

Thank you so much, ok i will try to include some theory about slabs

[@MasterCivilEngineering]

Yeah

[@saritarnav]

If AST min (dist steel) > AST ( main steel) what does that explains? Does that mean reinforcement is not required?

[@petraalbatra9898]

same question

[@badotaipodia5304]

sir 1 question plz.. To find effective depth , d=span/（basic value *modification factor）is this correct？？？

[@structuralanalysisanddesign]

Ya its valid

[@badotaipodia5304]

sir why you have not used modification factor？

[@GauravGupta-yu1cu]

Which book you use for this problem

[@structuralanalysisanddesign]

Limit state design of reinforced concrete by B.C. Punmia

[@_edits_mtv]

33:00 here you have said that Ast required is 290 but shouldn't it be Ast min i.e. 210 mm^2?

For one way slab 180mm to 200mm depth should be kept for satisfying all criterias

[@rajeshnaik5556]

sir Ast Or Ast min mai compare keya to Ast.. =291 aya maximum but aapn jo provide 8mm diameter lagake.. ast nikali hai o kis liye hai..

Sir modification factor is not taken why sir

[@biswasmihir0001]

Dear Sir, could you please tell me how to find/get the live load of any slab?

[@jayaprakash3853]

I need a barbending drawing for this one way slab design

[@vinayakg4064]

Sir Is it reinforcement drawing compulsory we hv to do...to get marks in RCC Polytechnic DTE exams ?

[@prabhatrijal]

So confused...load unit is KN/m^2 and then using this unit, moment will come in KN only not KN-m!!!????.... Edit: if you are confused about it than this is the answer: Live load is in KN/m^2...and we have to multiply it with b(in case of slab analysis b is always 1m ) and hence the unit will be in KN/m...similarly for floor finish also multiply by b....

[@structuralanalysisanddesign]

[@nasirahmadkhairi4550]

Hi sir When we design a RCC slab to determine the thickness of slab why we dont determine the thickness of it directly? I mean why we find an initial thickness for it by estimation at first and then we select a suitable thickness. Is there any rule to follow in estimation step?

[@structuralanalysisanddesign]

Hello, initially we take it from L/d ratio as a guidance and than check for the d with respect to moment whether it is sufficient or no

Sir in the last step of development length calculation bond stress value should be increase by 60% because of Fe 415

[@MasterCivilEngineering]

Yes dear

[@NitinNarkhede-c9x]

Sir, Your way of explaining is away some. For 3m clear shorter span of any longer span one way slab having same load condition, does the design will be same as we considered 1000mm length of strip for design for longer span length? The deflection check ratio for thickness assumption of 20 for simply supported skab at initial stage gives very high thickness from practical point of view as slab of 3m ckear shorter span having 150mm effective depth will be uneconomical from concrete point of costing..... I think. Please guide 🙏

[@saikrishna889]

Hlo sir The floor finish value 1.5 or 1.75 kn/m^2 Pls tell which value we can assume. Thank you sir

[@structuralanalysisanddesign]

You can assume appropriately, usually in academic numericals they take from 0.5 to 1.75 KN/m2

[@பொன்மனோஜ்சு.பொ]

If development length check becomes unsafe then what to do

[@swarupdass7223]

Sir, How to place Ld=750mm for a d=150mm Simply Supported slab?

[@Echoes_of_infinityy]

Slab rests on beam so the development length of slab will go in beam, usually beam have depth more than 230 mm

[@BeatYourCompetition]

How the unit of load became N/mm^2?

[@structuralanalysisanddesign]

On slab load will be in per m2 or mm2
