LOVE YOU ALL MY VIEWERS & SUBSCRIBERS .

Very Informative... Shukran....
In case of vertical seismic is there further scale up required or not.
great work sir
sir,
we have to match the of base shear of EQX with RSX and base shear of EQY with RSY by scaling factor.
Similarly we have to match the base shear of RSZ by scaling factor with others or not ????
plz reply
thanks dear , would you mind if i get the files (ETABS , and cad ) To apply the Syrian code on the same model to compare the difference between the two codes?
Why did you not include load combination for the wall? Do we need to analyse the walls separately by its own load combination?
Can you share the resource used for tutorial. Its nice and excellent too.
If you can make a video on vertical seismic effect in static (Eqz), it would be great.
Sir, after the analysis why is the mode participation ratio was considered only from SumUx which came around 70% and why not from SumUy and SumUz? Some mode numbers have around 97% from SumUz, so why are they not considered?
And what effect does the analysis or result will have if we do not keep the mass participation beyond 90%?
thanks dear , would you mind if i get the files (excel , word and cad ) ?
how can I define a In-Elastic Response Spectrum ?
very informative video as always. I have few doubts.
1) Why did not u use manual combination for the previous video as mentioned in IS code.(I know combinatin will be different but still)
You need to be member to support the channel.
Sir, when u have taken load combination case 2 i.e {1.5[DL+-(ELx+-0.3 ELy+- 0.3ELz)]} and the other one, u have taken the live load, soil pressure and water pressure also. but I think the live load, soil pressure and water pressure should come under the imposed load section i.e case 1 only. In Case 2 and Case 3 as per IS 1893:2016 we should not consider the imposed load. please see that part (10:50 min).
Thanks for the video.
I think load combinations should be in this manner, Rsx+0.3Rsz and Rsy+0.3Rsz as the building is oriented orthogonal horizontal directions. Therefore cl. no. 6.3.2.1 & 6.3.4.4 of IS-1893-2016 shall be followed. Correct me if I'm wrong.
Your clause is applicable when you will not consider vertical seismic effect. Check Clause: 6.3.4.1: "When responses from the 3 EQ components are to be considered, the responses due to each component may be combined using the assumption that when the maximum response from one component occurs, the responses from other Two components are 30% each of their maximum." Accordingly they given the combination equations.
Sir where I can get proof of Model Eigen and ritz specifications??
Assalamualaikum sir.. I have a request for uh can plzz u plzz design the structure of 15 storey building with essential details and structural detailing and drawings using IS codes and economical as well... Plzz make a complete tutorial which have complete drawings and detailing and tell us what kind of details i have to see in the results for drafting the model in autocad just like structural engineers do and they make a complete detailed drawing on A1 sheet.... Plzzz sir plzzz make a toturial
I will try my best
Sir, Can you please provide the word file resource for it
Do you learn full coarse on online
Sir after getting the design by the etabs... How can we make it economical?
Check the playlist in static method I have discussed how we can optimize design- th-cam.com/play/PLiK7qkGjS_tKwxzi2H7-tzCBrBcHlUWEu.html
@@Decodebd thanks a lot.
Hola sir.
Can you please make a video about Performance Based Design with Nonlinier Time History Analysis? (FEMA and ATC regulation).
Thank you very much sir.
Will try
Exeelent video .. plz the axial sheet ? thx
very helpful
Glad to hear that
Will i have to always do this process in every structure? Plzz rply me sir
I have explained everything in this tutorial series, when and in what condition you have to follow the process.
how can we see storey response plots for Rs-z like we do for x and y direction
In storey response plot you can not see it because there is no option to select "Z-Axis". From deformed shape you can click on the joint for which you want to see displacement along z direction.
@@Decodebd and then through Excel we can plot a graph..
Excellent once again, have upgraded to loving fansub, so plz share the cad, Etabs and word file
Bro i m not able to join as fanbase. Card error can you help
Sent!
@@Decodebdgot it, time history for the same building plz
you can give? Word and excel file?
Sir i want to join but card error show everytime what i do...please help me. ..i change card but problem not solve.
I don't have any other option dear.
sir is it possible for me to get this excel file. Please
plz share the cad, Etabs and word file
Sir, Can you provide file resource for it
Check mail.
I have subscribe and member. Please share your step tutorial.
