Thankyou so much!! Helped me understand Etabs better!! Excellent explanation. Getting to know more about the different options in Etabs 2015. Thankyou once again Sir.
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?
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
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 ??
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?
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
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?
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
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?
Hii sir..maine autocad se plan input kiya hai bt edit me jake grid line on kiya..bt show nhi ho raha hai..aur mera plan bhi select nhi ho raha hai...can u help me..?
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.
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
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?
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)
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
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.
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
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.
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
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.
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.
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.
Hi, i was trying this tutorial but i got stuck somewhere, i hope someone can help me out. when entering the grid system data ( X-Grid data ) @4:04min, you entered 1.2 and 2.7, how did you complete the other data in the grid? i failed to complete it thank you
Thank You, i thought there was a short cut that you used to complete the grid data...Your Videos are helpful, i would appreciate if i could get your email address to ask you for more help...Thank You Sir
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.
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?
Hi thanks for the tutorial i just have a problem when i try to render in 3d view unlike you @43:15 i get an error message 'could not initialize the model object' & when i hit 'Ok' i get another error message saying 'an abnormal condition has occurred. program needs to terminate'. any idea how to resolve it ? thanks.
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.
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.
+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.
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..
hello sir i want to know about long span building upto 400ft long. this because i want to know how to analyse such long building after breaking at every 100ft.
i went with this tutorial.. but at one point while drawing beam i could only draw the external line,,,, in ur video after drawing external line the internal beams automatically displayed..... i cant understand y internal beams didnt automatically displayed after drawing external beams... i hope u would help me with this problem
Thankyou so much!! Helped me understand Etabs better!! Excellent explanation. Getting to know more about the different options in Etabs 2015. Thankyou once again Sir.
Overall your modelling way was awesome. Really appreciate your modelling. would go for other tutorial tomorrow as well Insha Allah

i checked my first story and cross check B5 and 23..can somebody help to me this..thanks
