Thank you
due to some PC problems our next etabs tutorial is delayed. I will solve it and upload as soon as possible.
@17:00 and @19:00 The relative distance 0.05 and 0.95 are ratios and not distances in cm. So for a beam of length say 5m, RD=0.05 will be 25cm (from end i) and RD=0.95 will be 475cm (from end i or -25cm from end j). Hence, actual distance of hinge from each end will vary according to the length of the beam in the model.
Hasan Shirazi yes you are right.
May I know how to generate the hinge state after i run the analysis? I had define and assign my hinge properties to beam and column , and i run for non-linear time history analysis with scale factor ground motion.
Fast reply appreciate!
thank you very much for providing such a comprehensive videos. I was wondering if you could provide videos for analyzing shear wall in details. How to decide the length and thickness of shear wall and how to optimize it. Where to decide the location of the shear wall in complex structures.
Thank you very much for response.
please provide video of pushover analysis by capacity spectrum method in detail
while modelling a high rise building , say G+20 in any zone in response spectrum method , failure chances are high after design ...so it is almost definite that if i go for pushover easily every hinges turn red , does that mean that building of that sort is not advisable if hinges turn red?....is it possible for all the building members to pass the design even if the hinges turn red in push over analysis ?
Hey.. m doing pushover analysis for frames with infills my pushover curve is not yeilding and m nt getting performance point wat shd i do
Sir,
If we analyse this Push Over with EQ in that case in Base reaction table EQ result is lower than push X max ..
So what we’ll do..
i have perfomed push over for a regular symmetrical G+7 building in zone 5 , here after the analysis almost all hinges turned red but i would like to know how to find at what magnitude of displacement , moment ,drift etc failure happened...?
can you please provide me video of pushover analysis of rc multi storey building by capacity spectrum method
sir please tell me that is this procedure is useful for frame with shear wall building
What are the loading combination use for pushover analysis?? They are according to FEMA, ATC or IS Code??
i have designed G+15 storey structure ,why hinges are not showing in internal beams. the error in assigning hinges. requested calculated properties may not br svailable for material or section property. please help me to solve this error
Thanks alot brother for the video, really appreciate the effort put into this. can you kindly make a video showing analysis to check reinforcement considering the lack of lap splice length in column. thank you
sir how to get performance point while using co-efficient displacement method of pushover analysis, iam working on comparative study by pushover analysis and following the same steps explained above, but how to get performance point ???
Sir How to model a equivalent diagonal struts replacing infill walls in etabs 2016
Hello sir. I m working on progressive collapse of high rise building.sir my question is after this nonlinear analysis how to find DCR ( demand capacity ratio) of flexural beam and PMM ratio graph result
Hi
I have used nonlinear static (Pushover analyses) for that building, but nonlinear case not finished run ???? i tried many times and for different model always Not finished run ?? even all steps were correct,
Hello sir, thanks for the tutorial. its my first time doing pushover, and i have a question. when defining load case pushover, how should we choose the load type between load pattern, acceleration or mode? i tried them all, and they give me different values in performance point. thanks in advance.
hi sir, i have a doubt in pushover analysis of rc building. i am doing a project on pushover analysis of G+9 rc building without shear wall and braces, with shear wall and with braces.
my doubt is howmany total number of plastic hinges do we get for a model without shear wall and braces, for a model with shearwall and for a model with steel braces. each floor has 32 columns and 54 beams. how do we define a plastic hinge? please help me out .I ll be looking forward for your answer. thank you in advance
Hi thanks, your videos are very useful to me. Pls can you upload Big hall with peripheral columns and beams lift room with shear wall design as per IS 456.
Hi May I ask you about pushover analysis on steel frames? in which order to we want to activate plastic hinges? should we get all hinges in beams first and then in columns?
It depends on the position of the point of application of load/displacement.
NEW VIDEO ON ETABS Check updates in recent Uploads.
Dear sir thanks for your precious efforts...@ 36.55 using plot type fema 440 EL why u have chosen spectrum source ASCE 7-10 general .Since we r doing in accordance with is code should not we define indian response spectrum and than chhose that one here...Plz clearify it will be a great help
Do we get story stiffness in pushover analysis
sir can i get the word file that you have shown in the early portion of the vidio. It illustrates all the steps and the definations of push over analysis.
Sir can you make seismic analysis of steel frames with eccentric bracing using pushover analysis...
Please provide some tutorials in ACI code too.
thanks
sir videos are very very useful.sir add some more videos about shear wall. how it is provided by using IS code.
Sir please tell me that u have used the full version of etabs or pirated one???
How to get yield displacement of rebar and unconfined concrete using strain from Push Over Analysis as defined in HAZUS-MH using CSI Bridge?
Hello sir
Can you tell me how to model x-plate dampers in etabs
I'm using etabs20
Whether the displacement you entered is same as target drift, coz Journal papers have Target drift given
No I have not considered any Target drift.
Hi there , want to ask is it possible to develop plastic hinge in time history analysis? because i' doing repeated earthquake which consider a several earthquake and time of rehabilation.
yes you need to use capacity spectrum with acceleration due to earthquake time history load pattern you can select when mentioning the load case PUSH-X and Y.
can you please provide a video on optimization of RC building for pushover analysis.
Sir yours videos are awesome ....can you also shared some learning PDFs of Etab ,sap and safe so that I can learn more and more....
Hi sir,
How to solve the error message: Error in creating frame element hinges. ? Since I try to run after creating beam hinges, meanwhile run with only column hinges is no error.
hi i need collapse analysis of a concrete frame building by using etabs
Hello sir,
I am following all your videos for my project work based on pushover analysis Multi storey building. Sir Can you Pease tell me that the same procedure can be adopted for the L-shaped multistory Building? or any another process is their for Pushover analysis using Etabs?
I am unable to find the document of definitions, if you could help me in this regard
Sr what is the limts of monitered displacement
How we decide value of monitered displacement.
Very informative!
while performing push over ....in some model i am getting performance point while in some not ..ie my demand and capacity curves are not meeting ....is there any way to make them meet in etabs pushover analysis ?
govind up u have to change the exterior effect or changing the hinges.
Hello sir can you please say me how to calculate demand capacity ratios for beams and columns in Etabs
HELLO SIR, CAN U TELL ME HOW TO DO THE PUSHOVER ANALYSIS OF STEEL FRAMED STRUCTURE??
can we get performance point for all the seismic zones for flat slab structure in etabs as per is codes????
yes
Can u let me know, how generate hinge results table after analysis??
hlo ji this video was very useful....thankyou ji.....can you uplod the video on pushover analysis of steel braced frame.....r else can u tell me wat is t difference between t both...I have doubts in providing hinges..can u please help me out
Why you DL not change in nonlinear and scale factor is -1
When we put scale value is 1 then graph is in -ve direction.
Plzz clear my concept
while assigning hinges, hinges button is not highlighted...can u tell me wer i have gone wrong?
how to do Pushover analysis for steel-Structure including wind, earthquake and response spectrum analysis
sir plz make video on pushover analysis on steel building with bracing
aur plz tell how to use pushover when bracing are there
Hi, This is Vamsi Kumar.
I am very happy by your videos on ETABS.
But can you provide me videos on SHEAR WALL, HOW TO CREATE THE TENDONS & PIERS IN ETABS.
Thank You so much for providing your Knowledge to use.So thank you sir.Please help use by sharing your Knowledge.
Best Etabs channel tutorial... pls sir can you Make a tutorial explaining how to model, analyse and design STEEL ROOF TRUSSES using angle steel and z-purlins. This I will be very grateful.
Thanks. I am trying to solve every problem, but need to wait till I finish the current design on Bracings. Next will be yours, so be updated.
Thank you sir, I will be checking... also explain the weight the roof exerts on the roof beam as gotten from Etabs.
Dear
I have followed your procedures but when I finished the analysis pushover says not finished please tell me why?
In which case pushover analysis is done ?
Good demonstration. However, it would have been nice to see the formation of mechanism in the structure. How could we ensure that the time steps will show formation of mechanism in the hinges. To achieve this do we have to increase the value of "Load to a Monitored Displacement Magnitude" in Load Application Control dialog box?
Hasan Shirazi In that case we need to do capacity spectrum method. This is just an small example.
Thank you sir 👑👑👑👑
sir please provide me document that how to analyze building for capacity spectrum method on etab
If we don't get hinges in upper storey then what it shows
Sir, How to analysis G+22 building using pushover analysis? Please replay

sir please send me push over analysis of flat slab building for all seismic zones as per IS codes....
Thanks for the video. I am confusing about ta capacity spectrum curve that performance point is not found in your tutorial.
Yes you can get that point by adding a non-linear dead+live load at the start of pushover. 👍🏻
Ok.
Respected Sir
I am having a building with shear wall which is rectangular in shape, i want to provide hinge in beam, columns and shear wall.
How and which Hinges should i provide?
Hinges for column and beam are shown in this video only.. Please watch this video for wall Hinges th-cam.com/video/v75u62GQReY/w-d-xo.html
Dear Sir,
I have performed FNA in SAP2000v14, but the 'show hinge results' tab is not getting activated. Can you please help me out?
Is that the case that the hinge results are shown only in static non-linear analysis or is available in ETABS only?
I don't know what you are talking about?? FNA ??
I have to do lab experiment to test a beam in the lab, but first i need to know the crack load of the beam using etabs. May i know how could i do that. Anyone could help me?
sir jii can you make a single vidio of interpretation of the push over analysis results.
Sir, How about Secondary Beam other Primary Beam, can i Assigment them in Hinge Properties for Pushover Analysis?
Gelfone Matatula yes possible to add. Add hinges as per your requirement.
Which software.??
it is very helpful to understand, if u upload the document that explained in video.
thank you
moonbookz.blogspot.in/2016/12/pushover-analysis-using-is-codes-in.html
Hello sir,
Which IS code did you use to carry out Pushover analysis? Indian seismic codes does not have any specifications for this analysis. Inform me if I am wrong.
Shahzeb Danish you are correct. Pushover method is given in ATC 30 and FEMA...
How to apply incremental lateral load sir??
I always have this doubt ..please clarify sir... We should do this push over analysis in time history method only? Or can we do it in response spectrum also? Please clarify my doubt sir please
You should do pushover to know the effect to structure when a known force or displacement is applied. Time history is completely different method. And Response spectrum is codal method with prescribed curve of response.
@@moonboyslife.. I didn't get what you told... Are You telling that i no need to consider time history or response spectrum in the design while running the analysis... Is that why you have considered only DL AND LL in analysis while running analysis.. Please clarify sir
@@anand4236 yes, while doing PUSHOVER ANALYSIS we need to run only NON-LINEAR load cases..
Not getting....I need seismic analysis of braced frames with eccentric bracing pushover analysis...
is it possible to perform pushover analysis in flat slab building ? ....since there is no beams how do i provide hinges ?
govind up u can apply hinges only to members not to areas. So you can apply for columns only.
to do push over analysis do i have to do response spectrum and time history to the model before that? or you just took a random model which has done that in your video
No no for pushover analysis response spectrum and time history are not required..
Can i get link of time history analysis
Dear Qamar Moonby,
I am dealing with pushover analysis of shear wall frame structure. I am trying to define plastic hinges to shear wall. As far as I am concerned, modeling shear wall hinges is not applicable in Etabs but there is some modifications have been done by researchers such as mid-pier elements. I was wondering if you could help me model shear wall plastic hinges by etabs or show me some tutorials or articles related to performing pushover analysis of concrete shear wall frame by etabs.
Thank you so much
Hamid Nikzad please refer to CSI tutorials, especially the one for performance based design in EATABS
it was very good video
Sir,how could you say its based on IS CODES
How to calculate target displacement ??
why we are not considering earthquake load in this model sir? if the model is in seismic zone whether the EQ load is considered or not?
For seismic zone you need to consider g value in pushover load.
@@moonboyslife ok sir...
sir.. how to define axial P hinges in case of struts ?
I think it is similar to that of the Column hinges.
Sir,as in this tutorial video,we aren't getting the performance point ,so what can we conclude from it?
life safety level we can use.
Great Videos. Keep it up. Could you please elaborate more on the curves you have showed? How to read them ?
Kaldoon Hussein sure I will create a video elaborating the curves on pushover.
Qamar Moonboy Thanks a lots.
Hello Sir ,
May I know how to apply hinges to braces if my braces is of concrete material
Since braces or/and struts act as columns, so as we apply hinges in columns we can apply column hinges in braces.
Thank u sir .. N I m not getting hinges for entire structure .. where might have i gone wrong
nice tutor
assalamulikum
thank a lot this kind of vedio .....
Welcome.
thanks
Respected sir,
This is Aijaz, from Bangalore,
Studying M.TECH in structure
Sawed some of your video of etabs,
My thesis are going on only 2months left.
Need a help & suggestion as well can you create a model of (pushover static analysis) of G+4 or any 'n' number of storey with bracing (any bracing like x, k etc) please ...
Thank you & regards
Sir, i followed all the steps of performing push over analysis in my model but after i started analysis the message reads as "error creating hinges in frame model". Can you please give your reviews on that. That would be really helpful.
Fehmi Yousuf I also have seen that error in one of my student's model. Then we have created a new model from beginning to do only pushover. Then it was fine.
Sir here I didn't get d curve sir can I tell me?,, how can I see the curve ofter analysing
You need to add variable non-linear dead+live load also.
Sir those displacement steps can we itself assign?? If so how?
Yes you need to use displacement method.
Sir koi bridge pier ka lia pushover anylasis per video bana da sap2000 ma ya etab ma
Hello,
This video help me to make pushover analysis in SAP 2000. Thanks.
But i have a problem, because my pushover analysis finished before construction collapse. I have control displacement set on 0,5 m, but analysis finished at 0,17 and i do not know what to do. I want my construction reach displacement 0,5. Maybe can someone help me? Thanks.
What about the hinge results? are they safe!!
Thank you for answer. Hinge are ok. Some says that probably numerical problem.
this is a wrong approach bro your results cannot be validated
what is the difference between fibre hinge and moment rotation hinge.
Ankita Tewari please follow the link for your answer. wiki.csiamerica.com/m/view-rendered-page.action?spaceKey=kb&title=Hinge
Moment rotation hinge is basically for plastic hinge.. for fiber hinge u go by finite element analysis method.
is any different while analyze the building with shear wall
yes You need to apply Shear wall hinges. Like coupling beam hinges in coupling shear walls.
BRO DURING NON LINEAR ANALYSIS I AM GETTING WARNING *ANALYSIS COULDNT FIND SOLUTION AT STEP 8* WHAT TO DO NOW. PLEASE HELP
I really appreciate your practice, These steps I just shown to show how pushover analysis can be done. Please follow the method given in th-cam.com/video/v75u62GQReY/w-d-xo.html
