Thanks you so much for being more than helpful. God bless you!
Extremely helpful, I'm appreciating so much. Good luck for you!
Hello all. Thank you DrDalyO for this and more great tutorials! I also had the same error as many have mentioned here. The error goes like, "Switching to a different shape is not allowed while elements of ... Element type 1 is not the same shape as SOLID65." The solution is to select your concrete part and modify the mesh by doing the following: (1) right click on mesh, (2) select "method", and change the method to "multizone". Apparently SOLID65 elements should have such shape.
Thank you DrDaylO for the video .
That's a very nice video. There are not many RC examples done in Workbench. After some time, I was able to come up with a similar model (including command blocks), but it's really good to see we are on the same track!
Keep up the good work and thank you!
Igor
Thanks! If you improve the model and/or verify it with data please keep me posted!
Actually, I am analysing RC structures subjected to fire, which is basically this, but extended for higher temperatures (material data, linked thermal and structural analysis, etc).
We shall definitely stay in touch :)
You have great tutorials! Can you continue making them please
thank u very much .. I'm learning so much things from your videos .. please keep going :)
Thank you Dr Its perfect
So good Dr.Dalyo
Thank you DrDalyO for the video! Sir, Are the commands used in this video applicable for lateral reinforcement as well? If not, what commands are to be changed ?
Thank you for the understandable tutorial.
Hi, and thanks for putting up your concrete modeling videos. One comment on the static structural model that you have developed: Viewers should note that the coupling connection between nodes reinforcing rods and concrete by node coupling works only because of the element sizes and placement of the rods in the concrete block. You have done it so that you have coincident nodes in the elements of the concrete block and of the rods. Users will need to ensure that they use low-order bricks so that the SOLID65 bricks can be substituted. It will take more work for the "general case" in which the concrete is carved up into a multibody part so that reinforcing bars can be placed along edges of the bodies that are the concrete. With mesh density controls along the edges that are shared between the line bodies of the reinforcing bars and the concrete blocks, it should be possible to have coincident nodes that can be coupled with reinforcing bar locations that are not quite as restrictive. I am impressed with how smoothly and quickly you are able to present. Nice piece of work!
Ok sir thanx for your good work.I will try it.
thank you for very interesting. Vedio ,,I hope is these are. available. ,, one Vedio. for. doubly reinforced. beam. also. thank you. for a nice last Vedio. about. all the ,topic of static sturcture ,,,continuo dr don't stop ,,many people are watting for you.
Awesome video! Thank you!
Thank you DrDaylO for the video .
I'm new to Ansys and Is it possible to model and analyze the above without the command blocks?
Also, Is it possible to include bond strength between rebar and concrete in the analysis ??
Thanks.
This tutorial is awesome. Thank you so much. I have 1 question, did you ever calculate rc beam strenght by FRP sheet?
I want to solve this problem using ANSYS, using analytical method and in natural experiment. So Im open for all advices))
it is really helpful video thank you very mush
Great video, thanks
awesme job, thanks man
Hello Dr Dalyo... Thanks for the video, it's been helpful. Can you please advise me on how to model prestressing in workbench assuming the same model was prestressed concrete beam. how would I add a prestressing force to the rebar.
Thanks you for your nice presentation.
Thank you!
Really helpful video..
I want to check a sandstone behaviour can I approach in the same way ?
could you please do a detailed video on soil-structure interaction analysis and design of a building? that'd be very helpful
DrDalyO, I had previously tried out this tutorial during my PhD, but I was using APDL. I can provide some comments here, but I also have questions. 1) Your concrete stress-strain graph for concrete plateaus at peak strength but the real graph for concrete shows strain softening. As I know, v12 - v14 cannot model strain softening and I think that's why you had used the plateau here. Is the only workaround for this is to use Explicit Analysis? 2) Why was strain softening able to be modelled in v10 and earlier? Were v10 and earlier using a different solver or was that an ANSYS coding error? 3) What are the limitations in Workbench (WB) that requires one to revert back to using (parts of) APDL on certain situations? 4) Wasn't WB supposed to replaced APDL, so why do those limitations still exist in v18? Thanks.
Hello Dr Daylo,thank you for uploading the tutorial!
I want to know if I can still work on the Ansys workbench if I don't have the command inputs from solid work that you've mentioned then please let me know
Thank you sir for uploading this video. I have a question about the pre processor command, does it have to be absolute 65 elements for concrete?and why must it be 65?does it matter if i changed the number of elements? thanks
Awesome video! Thanks a lot. But I have a problem, how could we analyze the prestressed concrete beam in Ansys Workbench？
DrDalyol
Can we have few recommendations in the modeling of prestressed reinforced concrete slab?
Hi DrDalyO,
thanks for nice tutorial. I have a question, since I am using ANSYS 17.0, there is no select mesh button available. The only thing I have here only Node (Ctrl+N) and Element (Ctrl+M)
Dear DrDalyO,
Thank you for uploading this useful video. Expecting more informative tutorials like this.
Can you please send me the link to the entire report of NGUYEN ?
Thank you,
Regards.
Thank you for the tutorial. I have a question. How to match the nodes of concrete and the ones of rebars, if the rebars are positioned random in the section? Thanks!
Great video! Thanks!
Thank you!
Dear DrDalyO,
Thanks for this tutorial. I have a question.
How can I get the full beam results though?
Regards,
Thank you for this tutorial, it's help me a lot to use ANSYS Workbench.
But i don't understand one thing, why you use the commend APDL for stress-strain relationship, and didn't put them in engineering data?
Can i put the stress-strain relationship in engineering data? because i have to model a frame under lateral loads
Hi sir,
thank you for your demonstration.
i tried to model a slab with rebar using this method for my research but an unknown error is showing.
it would be helpful for me if you could upload a video about modeling a simply supported slab in ANSYS 17.2
Thank you
Thanks for sharing!
I almost do the same thing, "more than 1 element in at least 2 direction are present."
I have this problem ,could you help me out?
Thank you DrDalyo for such a useful video. However I have a question that, is it necessary to use command?
Dear Dr, for Ansys 2021 R2, can we use the same method to assign the element type and material model as shown in this video? I mean you assign command for each of the geometry element. Thank you
hey dr thanks for this useful tutorial i just want to know that how to expand the symmetry to view the full beam
thanks and regards
Thank you DrDaylO for the video .
An unknown error occurred during solution: "your product license has numerical problem size limits"??
May you arrange stirrup rebar in order to learn how you provide bond between longitudinal rebar and shear rebar ?
Dear Dr, I ask you in recent version of Ansys workbench static , the bond slippage between bars and concrete can defined as built-in without command ?
Hey! I'm new to Ansys. Is it possible to apply a force in the center of the beam and measure the cracks opening in the software? As if we were using a hydraulic press?
Sir could you please tell me how to add reinforcement ratio when I use the APDL command to model one beam?This tutorial has introduced us the way of discrete model and now I want to set up a smeared model which need reinforcement ratio.
Dr DalyO, thank you for this very helpful video. You have mentioned that there are other tutorials that do similar static modelling for concrete/rebar from within Ansys APDL - could you point me to these tutorials please that you refer to when you get an opportunity. From APDL, I am presently endeavouring to model concrete/rebar with stirrups (eventually studying the effect of openings within the concrete beam); I have come across a few relevant tutorials using APDL but would appreciate if you or any of the community could point me to other relevant tutorials (using the APDL development environment please). Many thanks
why is it so important to make connection (that we did before meshing) ? is it always required to make connections when multiple bodies are involved?
R,MATID,12,,0
The 12 on the last line, does it represent the rebar radius, diameter or area? I saw a document were someone put in the rebar area instead.
Also, you put the concrete crushing stress value as 25 but the compressive stress from your data points for the concrete stress strain relationship is up to 30.
Please provide info on this.
Also, i modelled the same geometry on ansys 19.2, and after analysis the impactor on top slides outwards, but when i keep the contact as bonded, it stays.
Please help.
2021 R1 workbench allows to define MISO tabular data for the material. Does that mean using APDL command isn't necessary?
Also DR. when adding the commands: /PREP7
ESEL,S,ENAME,,65
ESEL,A,ENAME,,180
ALLSEL,BELOW,ELEM
CEINTF,0.001,
ALLSEL,ALL
/SOLU
OUTRES,ALL,ALL
Do you not have to change the 'ENAME' to something else? Such as the Support so the errors do not show up?
how to model stirrups
in RC beam
What changes should i make in the modelling if i want to wrap the opening alone inside and around with gfrp sheet...?
Hi, thanks so much for your videos, Im starting use Ansys because I want to do a tesis, and your videos are helping me so much.
I'd like to ask you something, Im really sorry to disturb you but I'd to like to know, how do you connect 2 materials without use comands? I cant connect steel and concrete.
Im trying to make a RCB but Ansys sends me an error and I dont Know what to do.
If you can help me I'll appreciate so much.
Thank you sir for uploading this video. I have doubt in concrete slab testing i analyse a slab with reinforcement and without reinforcement but the result for the both model is same. Sir pls help me in that problem
Bro u amazing
Hi,
Can you make a tutorial of RC Beam/column with FRP? Really appreciate it.
Thank you>
i was about to ask this too. i think i can do that using staad but in ansys i dont know. 😅😅
Dear Dr DalyO
How can I obtain crack formation by time of analysis?
Thank you in advance.
Thanks, DrDalyo. I met this problem 'Element type 1 is not the same shape as SOLID65. Switching to a different shape is not allowed while elements of type 1 exist.' It seems when solid65 tries to override Structural Steel, it fails. Do you have any idea about how to fix it?
I have a question. I'm doing my project on magnetorheological shear thickening polishing for brittle materials. However, I'm doing simulations with ANSYS software for CFD, and I have obtained satisfactory results. But for static structure, I want to check when cracks and fractures will occur and how the penetration of grits or abrasive particles could impact this. Could you please help me with this?
Thank you DrDaylO for the video .
I'm new to Ansys and Is it possible to model and analyze the above without the command blocks?
Also, Is it possible to include bond strength between rebar and concrete in the analysis ??
+amr ali it is possible, but you must do it in APDL
how to made it in APDL
I have the same question, the command objects don't work in my model, and I hope there is a way to enter the elements types and material properties by APDL and continue all the other steps in Workbench. I would be very grateful if you helped me
If we model reinforcement by slicing the concrete material and provide a bounded contact with the concrete, would it be right ?
Sir, nice video,,
Can u guide me how to use combin40 element for joining two structure with spring and damper type elements
Thanks for the video. I have an issue with the commend input. i tried to input paste the concrete command to ansys but it just won't paste. Can anyone provide any suggestions?
it is excellent video. sir i want to make tapered rcc beam or haunched beam so how to give non linear section to the beam and how to make model and how to give material like concrete and rebar
Sir please explain how to give prestress to the beam
please how can i define bond between concrete and rebar in ansys workbench such as (combin39 ) or spring 14? if you can send me code for this definition
Hi, for link180 element the radius assigment via a real constant is not supported from 14 and later. Instead of you should use SECTYPE and SECDATA commands
Hi Dr ur video was so helpful for me just one more thing can u explain more about Concrete and Rebar commands and thank you so much
Can you please tell me the analysis of a structure in case of support displacement .
how can i specify that the comands for the stress-strain curve are for compressive or tensile stress only ? concrete doesnt have the same stress-strain curve for compression and tention and i need to input both curves. How can i do that? I mean the command you used was for compression or tention ?
funny thing happening to my model when i add APDL. the force i apply is in Possitive Y while the deformation i get is in the opposite direction.
is it possible to get shear cracks using ansys. to get flexural cracks we give cracking stress and crushing stress. in the same way is there any code or command to get the shear cracks.
DR. DalyO i would like to know that how we can do the modal analysis with the help of simply supported beam in ANSYS
Can you please tell me how to model a steel concrete composite connection using conta173 and targe elements ?
Sir I am doing transient structural analysis, I am confronting with convergence error. Can you help me in resolving it?
Can a method like this be used to simulat tied reebars? And how would the ties be treated?
Realy very nice vedio
+Sunil Chopdekar thanks!
How can we find out shear force and bending moment diagram for a simply supported beam with some load? Hoping for a suggestion from you sir. Thanks in advance.
sir..plz give tutorial on analysis of column strengthened by angle steel shapes and strips using ansys workbench
I have a problem my geometry is complex so it's a tetra mesh is there any way to use the same command the solve is give me error because of concrete elements
Hello Sir,
I am new to ansys and i am trying to model circular concrete column with biaxial bending. While defining the concrete material as per the apdl commands I am getting an error as, "Element type 1 is not the same shape as SOLID65. Switching to a different shape is not allowed while elements of type 1 exist". Also, if I am to model 3D reinforcement, please can you guide me with the commands for rebar as solid65. Please guide me asap
Hi, I can see concrete material in Ansys workbench 2023. Is it okay to assign that concrete to my reinforced concrete beam?
HI,yuor video is very useful for us ,a lot of thanks.we had conducted a non linear analysis on RC beam. we would like to know
how to visiualized cracks. thanks
Sir,I have a doubt.solid65 element is used for concrete . It is used for all grades like m25, m30 and so on....so how could I particularly use it for a specific grade?should I have to alter it's command
I think to avoid error in solution as appear when use solid65 for beam models , should choose dropped mesh for element midside nodes
How then do you determine the compressive strength of the beam with ANSYS?
If we did not want to use command file then how we will give bond property b/w concrete and reinforcement bars ???? Plz explain it
Hi have a good day sir,
How can I obtain the value of the bending angle occurring at the support points of the beams.
''Node 4 does not lie on or near the selected elements. The CEINTF
operation produced no results for this node." I have this warning... do you have any idea what is happening?
Can you please create a post-tensioned RC concrete beam model simulation. How to simulate the cable that compress and cause bend of a beam
Can you please show how to add stirrups in the beam? Thanks
Hi, want to ask. If i click the solution for maximum principle stress, the impactor is moving out from the body (concrete). why? can we lock it so that it cannot move?
Hi Friend,
I want to add properties of Fe250 steel and M30 concrete ....can u show me where to change the commands.....
can i just simply click on engineering data and select Engineering data sources for Concrete Material properties rather than insert the commands?
Hi Dr DalyO! May I know how can I define the C50 concrete material propreties?
Hello, can wen use Body interacter in static structure analysis?
Fatigue analysis in abaqus using beam model
Where can i get these infos which are included in Command file ?
Must commands be added for like these analysis? Why did we enter that?
I'm looking forward for the answers. Very educating video. Thanks sir !
please see the description of the video for the command file. Yes they must be added in workbench, if you use APDL then you can do it there also.
Hello Dear DrDalyo!
Thank you for this useful video.
Could u make a video for (shear Wall or RCC wall ) with biaxial loading, how would be deformation and cracks.
Thank u very much, waiting for the video.
Me too waiting for that plz
