[@civilknowhowtutorials7100]

+Arvind Kumar Thank you..:-)

[@galalhashim6371]

A very excellent Tutorials .awesome

[@dhrupalpatel4825]

VERY GOOD EXPLANATION Please explain 1) Why 0.7 & 0.01 taken in a moment of inertia and torsional constant 2) only concrete property apply but what about steel bars (i.e. FE500 or FE500D)

[@emanuelbedoya6541]

Thank you very much, your tutorials are very clear! Thank you!

[@thulodon]

Why is the effective moment of inertia taken as 0.7 and torsional constant 0.01? Are there any relevant indian standard codes where it is mentioned??

[@nightgaming466]

Moment of Inertia for column 0.7 is multiplied for columns

[@sharanu1629]

very nice and i got lot of idea about steel and concrete design

[@rupalsapra]

Everything was perfect.... Great job.... Thankyou so much

[@orlandodenelson3030]

Thank you for the Tutorial. It helped me a lot.

[@arunndinesh]

Thanks bro...really good way of explaining...nicely presented...post more...!!

[@civilknowhowtutorials7100]

Thanks bro ...:-)

[@SanthoshKumar-my6fw]

Hello sir.. you have not considered the column offset/eccentricity from the grid center line (between 0 & 90 degree orientation columns) as per the centre line layout.. doesn't this affect the design?

[@DesignReady.]

Can i design beams and slab only i don't want to design the column it possible to design without assigning column?

[@mohammedasimkhan3507]

hello, you doing great job want to know why you have changed the torsional and moment of inertia values ?

[@catherinemg6554]

Loved your explanation ,Thank you

[@chin3884]

Very nice and understanding. If there is a basement floor, retaining wall to retain the earth and under ground water tank, how to incorporate them in modeling?

[@jerinj4u]

Great tutorial... All best for future..

[@civilknowhowtutorials7100]

Thank you...:-)

[@avinashiytha9803]

Very gud tutorial. But I have a doubt regarding the intersection of beams. There will be primary and secondary beams right. ? If take the beams continuously, wouldn’t the beams will b designed neglecting the intersection. ? I personally think that main beams be continuous and the secondary beams should be splitted at the intersection.

[@nasratullahamarkhail3217]

Sir, generally (not for this example), if we want to define a diaphragm for RC buildings, which option should be selected? rigid or semi rigid??

[@arpitarora1489]

sir, i just started learning the software. I couldn't get that Master Storey explanation. Can you please tell me something more about why we assigned pstorey as master storey and how does it affects the modelling?

[@swastiksubedi]

Which is the exact level we should keep the support??? The foundation level, the ground level or the plinth level?? If it is ground level what about the structure below the ground level ??

[@narayananjayachandran831]

Hey, Great Video and commentary. Really appreciate your effort. Thanks a ton. one small question. I agree that you are applying the slab as a membrane. But why did you apply the lift walls as membrane ?...They are basically shear walls too and will participate in resisting seismic lateral forces right? So shouldnt it be applied as Shells?. or is it not going to take part in seismic load transfer?, Please clarify and enlighten me.

[@viku4]

ur correct, it should be defined as a shell

[@abdullaababiv6622]

Sir, thank you. How to relese the moment at end support if support width is 80 cm, release partial fixity only happening when support width is 20 cm.

[@MuhammadAwais-yy5oh]

nice explanation

[@huzeinbile]

thnkz sir excellent video but one question how you found torsion data you entry at section properties when was assign beams?

[@kiranbirdi556]

this video is really helpful but i have one doubt why we have made 8 noded slab for irregular shape and how it is helpful in load distribution mechanism?

[@thresmiphilip5500]

Great video...explained very well.

[@civilknowhowtutorials7100]

Thank you..:-)

[@shaikhasgar1684]

U had champer the edges of exterior slab at story 1 but u wouldn't show for beams and the column to support the slab.....plz help me ASAP.....i hd stuck on this

[@sami786samandari]

Thank u so much sir Awesome explanation ❤️

[@malsoma07]

Hi, can you do a tutorial on modelling of Step back buildings?? would be very helpful! btw, you're tutorials are awesome..thanks.

[@civilknowhowtutorials7100]

+Malsawm Dawngliana will do one..

[@faizanshaikh6036]

Sir if I want to delete Sun shade from ground what should I do? Because in my plan it is drawn in bottom story also

[@CrimsonTuber]

Hi, I don't understand why the slab should be spanning along the long direction at 29:09. I thought slab should be spanning along the short direction where to load will transfer to the longer beam first since there is a shorter load path?

[@engrRGV]

You are correct. Video is wrong

[@ahmedhyd867]

Dear Sir.....Thanks for this Etabs videos,Nice explanation with good english. Easy to understand, It will be very helpful if u could upload tutorials on Short and long column RCC (slender ) effective length calculation using etabs so also design Do we require to change MI modifier to 0 .7 in case of frame element

[@civilknowhowtutorials7100]

+ahmed Hyd yes u have to..

[@pgassociates7658]

@10:35 why you take moment of inertia property modification factor as 0.35?

[@vijayashalini3700]

yes am also dou..... t plz tell me

[@mohameddaahirafrika3504]

Excellent video, Could you pls help with more explanation on how you put your drew the beam @ 12:52, i tried but all grids are selected and i wanted only to select and place beams on the grids that you selected only...Thank you

[@m.shaihanayub7179]

Very useful video. I just wanted to ask if I draw one panel as a whole and then automesh that by choosing default option. Will that be right?

[@vivek123nani]

i am not able to assign slab when i start with the draw rectangular floor/wall when i click the joint and drag the cursor i doesnt show the varying dimension just above the cursor like in your video and i am not able to assign the slab plz help me

[@punyaarthun2233]

Thank you for the video. It is one of the best etab video tutorial. Can you possibly do a video on safe as well.

[@DesignReady.]

please how how to import plan from auto cad and then show how to proceed further

[@raktimbarua6973]

It's a very good tutorial to understand the basics of Etabs. But I would like to know two things: 1. Where did you find the values of torsion constant and moment of inertia values? I am from Bangladesh and in our building code (BNBC) I don't find any provisions for those. If I take those values as 1, would it be impractical? 2. Should the beams be continuous even if the beams cross other beams at one or more points? i.e. beam along 3A-3J should be considered as a continuous beam whereas beam along 4I-2I would be continuos too. is it? Note: I didn't go through other comments. So I dont know if you have covererd these questions. Even if you do, please repeat that.

[@civilknowhowtutorials7100]

+Raktim Barua stiffness modifiers are based on crack width moment of inertia...n about the torsion it's specified in asce code

[@ujjwalrijal1056]

i cant see the MIDPOINT shown in beam while placing the slab what should i do?

[@roshansharma1655]

can i get any video related to shear reinforcing and longitudinal reinforcing which is calculated in MS-EXCEL.... showing different checks...the chart to show calculations of stirrups gap calculation.....and various others chart

[@sami786samandari]

Really really helpful Thank u so much sir ❤️

[@ALLisWELL-kp1my]

Sir,3d rendered view option is not showing in view.only showing 3D rendered view (Ray tracing) option.what should do...???

[@Vasilijz395]

Sir I've tried to try to usse etabs to solve my previous seatwork in structural analysis using portal frame method, and etabs have generated smaller shear,axial and moment values compared to my manual solutions. Sir, I hope on your next video you'll be solving some easy 2d frames and show to us the generated values using etabs and using manual solution.

[@VAIBHAVSPAL]

THANK YOU SIR I HAVE LEARN NEW TOOLS THANKS

[@sremix2818]

Please please please help me sir, how to define cracked section in etabs? it would be good if you show me the way, i have tried by changing moment of inertia in property modifiers but deflections, moment etc results remains same as when the value of modifiers are 1

[@walkwithme1967]

Hi, Can you please include the methodogy of modelling coupled shear walls?

[@engrshamsurrehman4599]

why to take torsion modifier 0.01?

[@civilknowhowtutorials7100]

+Engr Shams to neglect torsion for design

[@engrshamsurrehman4599]

Civilknowhow Tutorials Engr.. if we didn't neglect, what would be the effect?

[@atifnawaz7623]

hi, firstly good vedios to learn. while defining a column , in the reinforcement or show rebar section by default it has 3 no of bars in x and some 5 bars in y direction. do we need to change that? or on what it depends no of bars in both directions. i mean we have to decide it?

[@civilknowhowtutorials7100]

+atif nawaz for analysis purpose...keep it as default

[@yashwanthkumar3700]

Easily understood. Tq u

[@engrshamsurrehman4599]

Engr also you not model the landing beam of stairs? wouldn't it effect the end reactions?

[@civilknowhowtutorials7100]

+Engr Shams one way slab is drawn connecting two beams...!!

[@hariomchandra9048]

How will u give property of 4bar steel with 16mm dia to a column

[@beenay18]

When i select none section for slab and assign load on it, slab does not transfers load to beams and columns. How can i apply area load avoiding the weight of slab.

In one way slab of this modeling, the span has been modelled along longer side..is it economical?

[@dharmajitjadeja8614]

Amazing, thank you so much for tutorial

[@rithisworld5904]

Well Explained...Thanks for this video...

[@civilknowhowtutorials7100]

Thank you .. :-)

[@saaiyogesh3366]

Can u compare Ast of long column in etabs and staads.....the Ast is not at all matching morever etabs giving greater Ast when compare to staad.....pls to explain

[@kishanaghera8375]

Respected Sir, is there any commands for giving offsets to beam and columns of outer periphery for matching edges? in 3d render view i saw slabs are slightly above the beam unlike in general practice top surfaces of beams and slabs are at same level, does that make any difference in analysis?

[@civilknowhowtutorials7100]

+Kishan Aghera don't b bothered about the 3f view....offset option is there in etabs

[@rujanshrestha10]

Isn't it necessary to define rebar properties while defining material properties

[@adiyapathampragadeeswaran2127]

very useful tutorial.

[@akhlaqhussain5122]

Nice tutoral

[@sahanahp6970]

Thanks a lot man it helps a lot .....

[@shrutgami1392]

Very helpful Sir can u add video for designing of isolated eccentric footing I face problems for corner column footing

[@yasar1abdurrahman348]

Nice explanation. I have a question regarding the stiffness modifiers. Have you adopted these modifiers from ACI? because there are no provisions for modifiers in IS code. Why do you think IS code is silent about them.

[@civilknowhowtutorials7100]

Thank you........Yes i have taken from ACI code.About the indian code what i came to know from senior engineers is that IS 456, though it was revised in 2000, most of the revisions pertain to durability clauses, may be because the team responsible for revision is from Cement and concrete research. Hence it contained most of the provisions from the earlier version of the code. So we may see the stiifness modifiers included in the next revision.

[@yasar1abdurrahman348]

+Civilknowhow Tutorials This is really sad if that is true. I also read somewhere that it might be because the dead load factor in combinations taken in IS456 or 1.5 while in ACI it is 1.2.

[@civilknowhowtutorials7100]

In the case EQ comb....our dead load factor is 1.2....n when w apply stiifness modifiers ...ther is 65 % n 30 % deacrease in the case of beam n column respectively.So i dont think the D.L factor of 1.5 can really compensate that.This is what i think..

[@MdNayem-to1fu]

Sir, What is the difference between reinforcement to be check and reinforcement to be design in column define?

[@oscareulatic2964]

Hi sir, How can we check the serviceability of the building in ETABS like drift, Center of rigidity and soft storey check?

[@nasratullahamarkhail3217]

Sir, Don't we need to mesh the membrane type slab?....Or the meshing is only in the case of shell type slab??

[@civilknowhowtutorials7100]

+Nasratullah Amarkhail in Etabs 2015...slab meshing gives finer results for membrane...in previous version membrane slab is not meshed

[@yashbirla6947]

thanks for the support...searching for dome modelling, hope you do that also.

[@civilknowhowtutorials7100]

+Yash Birla sure

[@shruthiarikeri1661]

Can you please make a tutorial on attaching a damper to the water tank which acts as Tuned liquid damper

[@harshkhatri3075]

Nice Explanation, But 1 doubt Is there any explanation for BM on axis 2 &3 to give exactly 0.35?

[@civilknowhowtutorials7100]

+Harsh Khatri crack width moment of inertia

[@er.abhisheksharma2240]

Why you made the modification in MOI and torsional rigidity

[@farazkhan2564]

as the slab assignment the front three slabs are also oneway slabs??? right

[@md.idrisalam437]

It is very helpful for learners. Is retaining wall a shear wall?

[@muhammadnouman6501]

Nope.

[@ananthraj8433]

i completed the model and then i analyse my structure for any duplicate frame or shells..but i see a lot of warning..even i checked again i m sure there is no duplicated beam.it shows like this " Story1, B5 & B23 are overlapping each other. Overlap =0. Check at (12600 13500 3000) " for most of the beams i checked my first story and cross check B5 and 23..can somebody help to me this..thanks overlap 0 ? can somebody explain this too.

[@abhi_dubey94]

Pls make a video on foundation design using similar plan.

[@nasratullahamarkhail3217]

Dear Sir, Why have you selected membrane for the slab type instead of shell?...Membrane will transfer 100% of the load to the relevant beams. While shell slab will bear some loads and transfer the rest to the beams which is realistic. Thank you.

[@civilknowhowtutorials7100]

+Nasratullah Amarkhail I am following the thick beam thin slab concept

[@viku4]

very good video

[@hamzalatif2]

i just start work on etab.. any one here to know how can change the wall height and opening for windows

[@ALLisWELL-kp1my]

Sir, what is process for below warning... *Warning: Area load transfer for storey 7.A1.Total loss=5.88 for load pattern...???

[@rashmi2585]

No Steel is defined.? And is there any reason y u changed ur modification factor. Usually it's taken 100 % that means 1. But in ur Caseu changed it.

[@omarjailan4598]

It is very helpful but when I define material I do not see the BS how I can get it

[@Mansoor2bfree]

very good tutor for me to learn this soft..very welled explained...can u upload tutorial for beam that are not placed symmetrically with column....but at an offset..i means center of beam and column are not coinciding....... as in real life situation.

[@mohammadmajeeduddin3545]

mansoor kathanawala I also faced such problem .how to model beams which are eccentric to column??

[@VGR566]

I THINK FOR THAT WE HAVE TO PROVIDE A CANTILEVER BEAM FROM BEAM CENTRE TO COLUMN CENTRE WHICH MAY LIE IN THE COLUMN. PRACTICALLY WE HAVE TO OMIT IT. BUT THEOROTICALLY WE HAVE TO TRANSFER LOAD THRO' AXIS WHICH ARE UNIDIRECTIONAL i.e. SINGLE LINE AND NOT THREE DIMENSIONAL.

[@Ayyubi12]

Hi Does anyone now how I can make second order analysis in Etabs on structure which consist of concrete walls. Another question is can I achieve second order analysis if I generate notional loads on my building? Thank you

[@msdqafzal6063]
