- Time History Analysis in Etabs 2015 deals with the procedure to conduct time history analysis in etabs 2015 on a G+6 building.
The tutorial explains the time history analysis by assigning the ground motion along both axis. Etabs 2015 provides the option of defining the time history function and scaling the defined time history case for analysis with respect to target response spectrum.Target response spectrum is defined as per ASCE 7-10 which is a predefined option in etabs 2015.In etabs 2015,linear time history analysis can be performed by linear modal analysis method and non-linear time history analysis by direct integration method.This tutorial deals with conducting the linear modal time history analysis in etabs 2015.Tutorial consist of following steps
(1) Defining the time history function 4:22
(2) Defining the target response spectrum 8:49
(3) Matching the time history with target response spectrum 10:18
(4) Assigning scaled time history as load case 15:46

Thanks for the tutorial Sr. You'r the great teacher.....
We appreciate your efforts, an excellent step wise explanation. Thank you very much. You are making people aware of design!
it is very nice and great explination in detail and speachless with u r tutorials and we need more more viedos frm u specially desining falt slab and prestressing for hope we will have them soon ..... wating for u r next viedos thanq.......
Thank you for your information and kind effort
It was very helpful
Thank you sir
Great effort indeed. Sir, I have to say that your videos are even better than the videos made by the developers of ETABS (CSI). Very clearly and professionally explained considering the recommendations of ASCE 7-10 codes. If possible, please make videos on Pushover analysis and nonlinear Time History Analysis because both are highly demanded ...lots of respect and God bless....
+Nasratullah Amarkhail thank you...glad to hear that
Hi! I was wondering about why you have adopted for total analysis time 12 seconds and for output time step 0.1 sec?
Thank you for the video!!!
Thanks for the video!!!
Can you tell me how you model the above building and will you design?
Thanks...very very....so clear...
Nice explanation sir. Please provide more videos related to modeling of complex structures and industrial steel buildings
Very interesting video go ahead sir.
Thank you for your nice and useful videos! If we have three different structures. the plan is one but the structure is different. 1) the structure is made of columns and beams. 2) the same add a few shear walls. 3) no columns and beams only shear walls. if possible to do dynamic analysis for all of them and compare the result. would be nice of you.
This is good informative video.Go a head.
Vey good explanation sir
Sir if possible, please provide such a comprehensive video for Pushover Analysis as well....Thank you...
Very informative video. Thank you. Can you make a short video on a similar basis for IS code specifications?
can you please make a video on applying time history analysis for a nodal point in SAP2000 for performing blast load analysis...
could you post a tutorial series full Hand calculation of a five story building.? it will much helpful to us and also your channel.
hi! great video! I was wondering, is there any way to export the matched time history to an excel or a .txt file?? thank you
Sir that was a great tutorial. Is there a way to change frquency of beam or column in etabs
Can you add a tutorial on Pushover Analysis in detail as this video is.
More informative.
Could you share the complete model so we can run it on our ends?
Thanks in advance
Thanks ..
Hi there , want to ask why Etabs always get the same maximum story drift even if I changed the ground motion scale factor from 1 to 20 , or even i changed the other ground motion from PEER , is it I'm doing anything wrong or need to modified the stiffness , hope to get some guide from here.
When I try Non Linear Direct Integration method for steel structure, hinges are not formed?
Salam /Hi. Thanks for tutorial with explanation.
Could you explain why time history acceleration unit g?
select preference acceleration time history which is taken from PEER website and the PEER provided ground motion data as unit g.
so, is that reason to considered time history acceleration unit g?
A very informative & helpful video. Would you please a make video about how to download time history function about a very specific earthquake (like Nepal earth quake -April 2015) from USGS website.
sir I'm working on a project "tuned liquid damper" on etab in this basically a water tank is coupled at the top of the building to reduce the dynamic characteristics of the building by the sloshing motion of the water in the water tank. So my question is how I can give the sloshing effect to water in the water tank for earthquake analysis because sloshing motion is the basic idea behind controlling the earthquake effects on the structure.
sir, please help me.
please upload the video for how to do designing in etabs
thanks
Sir will you please make an vedio for how to know our analysed and design building will be safe , stable and economic , on which output data we will decided the building is better for construction
verry good explanation, but how you define FY?, mine only shows FX...please be kindly respond.
How did u get the total analysis time for Time history...can u plz explain..
thanks a lot sir. i want to ask you some questions if you don't mind. what is masonry load and why is it in the group of super dead?
and if i separate the Time History in load cases, i divide it to "Time History X" with only U1, and "Time History Y" with only U2. is it okay?
Also i really hope that you can upload time history analysis with nonlinear direct integration. thanks a lot
Sir, why are you not considering the P-delta effect while performing Time History Analysis?
Why is it necessary to match static and time history base shear?
My base shear Fx shows me kN but in a really small number like 7,..... 6,..... can any of you tell what is wrong with my model?

GANESH LAL this is also my question if you got the answer please share to me thank you 🙏
I’m doing my thesis but how to put TMD on the structure? If you know please text me
Your scaling has screwed up the input ground motion, especially in the y-direction! X-direction scaling is probably acceptable though. But, look at the end of scaled time-history of y-direction. The acceleration data just blew off to get better matching in the long-period of target spectrum, which just imposes such a large low-frequency input acceleration to your structure. It can have good and bad implications; one can argue it is not a good data to be used for design purposes or one can say those data are in the very low frequencies away from the period of structure despite the large magnitude and it wouldn't affect the response as much. I would probably cut-off that last part of the scaled time-history where there are large low-frequency accelerations. Your purpose is probably here to teach how time-history analysis is done, but I just wanted to note a detail that ETABs screws up and engineers need to be cautious.
Sir wat can we do if proper matching of time history data is not there
We have the option to download the scaled and as well as the un-scaled ground motion data PEER website. In case if we download the scaled data, do we still need to do the scaling or matching command in ETABS?
+Nasratullah Amarkhail has to be scaled with target response spectrum...just check whether it matches or not
I have a questions if you please reply me... In your case, you have chosen 2 different types of ground motions for X any Y axis....Why not to chose the same type and apply it on X and Y axis separately? Thank you.
+Nasratullah Amarkhail that a good qs...u can ..in this tutorial I considered the actual scenario...u can consider the same time history along both qs..it's all up to the engineer
The units of my aceleration data is cm/s2, should I change the scale factor because this?
yes
I need help sir did we need any design of our building?
Salute sir. well done, where i would wish you to advise is on browsing x and y input data, me who using Eurocode 8, how can i generate that data.
thanks. Well done once again
how did you know that data is the x-axis one and the other is the y-axis one?
Sir, how to find Ss and S1 for Indian sites?
I am not getting those 2 files. Could anyone please share the link or the file itself..
How to download the peer ground motion database ?
thank you sir your ETABS videos were very helpful for me and I was wondering about why you have adopted for total analysis time 12 seconds and for output time step 0.1 sec?
i think analysis time was 10.7 in this example
Hi,sir .You can give me file Time history .Thanks
Hi there , i'm new here , current doing my final year project , want to ask is it possible to make a several earthquake in different time period as i'm doing repeated earthquake as consider effect of accumulate spread of damage , hope to get reply , thanks!
+Joon Hong Tai no...u can only hav one at a tym
Thanks for reply! but what does the arrival time means in time history analysis , will it consider as a sequence of earthquake effect so the accumulate damage of earthquake can be obtain?
sir, the points per line are 5 instead of 1, Greetings
Why have you adopted ASCE for target response spectrum.. why not IS1893.. If IS 1893 used, what will the criteria while scaling..? Please reply
Becoz IS CODE IS NOT GOOD AS COMPARED TO ASCE
Sir how did you find the ground acceleration data? can you provide a direct link please?

hello
please tell how you define Base FY, which is shown in plot function. There is only Base FX shown in my file
Yeah me too. Have got the solution?
NONLINEAR Time History Analysis IS NEEDED ???????????
Sir, How is the long period transition period determined to be 8 ?
+Nasratullah Amarkhail check the asce 7- 10
Sir, In the ASCE 7-10, the maps to determine TL are for US states. How to determine TL for other countries? Do we just simply assume as TL = 8 for countries other than US?
Hello sir. Can you give me the earthquake acceleration data ?
Bro if possible provide ground motion data
You obtained the scale factor as 1.54 and 1.48 then why did you insert 1.89 and 1.82 in time history load case?
He wrote it on the screen, just pay more attention....anyway its the result of moltiplication of the old factor with the one that came from the table...check the video and look on the screen he writes the calculation there
@@dion5924 hey asshole, try to be more polite when you talk to someone in your life
The values he obtained by calculations were 1.54 and 1.48 which is what I said
Then why did he put 1.89 and 1.82, for that I was confused
If you are so smart then atleast show the timing in the video in your comments
Hello sir, could I have your time history files?
Please send your WordPad file (imperial valley earthquake 1979)
how can apply a blast load on steel and rcc buildings
Sir your video's are so good but sir send the procedure from start to end
i.e how we analyse and design a small and highrise structure in etab
How we apply wind load earthquake load etc
Thanks for the tutorial Sr. You'r the great teacher
