- ANSYS Workbench 17.0 Tutorial for a three-dimensional (3D) Bridge Truss with a surface slab as the platform. In this tutorial I will go over how to create line bodies or trusses in ANSYS DesignModeler as well as Surface Bodies. We will then go over creating manual contact regions between the truss and the platform or surface, creating the mesh, creating our fixed support and roller constraint (displacement), and finally the pressure load. We will analyze the stress results, deformation results, axial force, bending moment, shear-moment diagram, and reaction force results.

the most explained video I've seen on Ansys. Thanks a lot.
Thanks for this video, it has provided the perfect introduction for a welded space frame structural design and analysis project I’m about to start.
Thanks!
Your tutorials are so much helpful for a self learner! Thank you so much Sir 😎👍
it was really clear & helpful and thanks for sharing the geometry
Very helpful! Good luck in next tutorials.
wowww....so cool and clear tutorial...thanks for sharing
I learned SO much! Thank you!
Thanks!
thank you sooo much it is really helpfull for me to understand ansys very much..
Very helpful information
Thank you men, you really save men :D
very helpful ,thanks !
thank you for such a detailed explaination
Welcome!
Grt explain sir...pls make video regularly that is very helpful who beginners who like me...
Indeed an excellent video. Thanks!
Thanks!
Thank you for this video! Man!
@@drdalyo No! I am not! I am Seanghai, Cambodian student who is studying Civil Engineering in S.Korea
Good work hero. I really like your work. One subscription from me.
great lesson.. :)
good tutorial.
thanks great work
Good luck in next tutorials
very helpful
Muchas gracias! Muy útil!
Muchas gracias!
Thanks +DrDalyO for another fantastic video tutorial. Really appreciate that you showed detail of steps especially in the geometry setup of the model. For beginners like me, the more details the better ! I have a question by the way: usually, for truss bridge, we model the connection of the truss to the base as "pinned" connection. The way you did in the video looks like it would be able to transfer moment. How would you release the rotation about y and z axes (the axes other than longitudinal axis of the truss) ? Many thanks
very good video!
Thank you
Thanks!
So helpful thank you! Any chance you can do an example on how to model a suspension bridge?
excellent video!
+Serkan Ali thanks! Please subscribe!
Thank you!!!
Hey Doc! Thank you so much for the tutorials, they are very useful. I know it is a bit out of time, and I don't know if you are still working with Ansys, but could you make some video about Microplane analysis? Thanks again!
can you please tell me how should i model joints where their is U Clamp in a truss?? and by any chance could you please tell me which analysis software should i use to get better results ANSYS or SAP2000??
Hi, That was great tutorial. Thanks a lot! I have a question, can we assign different material to the beams , say half of them made out of aluminium . another question is that is it possible to assign material coating on the beams?
Thanks!
great bro my problem is solved
Thanks for the tutorial!! I'm wondering the cross section definition. Does it have to associate the cross section to line body every time I create a new line or a new cross section? Can I go back to edit the material source(like adding new one) when the mechanical module window is open? Thanks for the answers!! Likes for your lesson:-）
all are great
Thankyou so much please share more projects
Thanks!
Can you please demonstrate the temperature effect on the bridge structure. Thank You
This is an excellent initiative. I have a little request to you to please share the modelling of a single span composite I girder bridge as I have been stuck in it. It would really ease my life. Please help me. Thank you so much.
Another question: usually for truss structure, the failure comparing stresses of the truss with yielding stress is not useful since buckling tends to occur first. Can you please make a tutorial video for buckling of a column or similar structure ?
Thank you
Welcome!
Useful Video, very helpful.
My assignment for University requires that I calculate Member forces of the trusses as well, could you offer me any guidance?
Thankyou so much for the video. I wanted to ask a help. I am trying to output the Maximum principal stresses as the negative stresses too. Can you please help me on doing that?
thanks man
Welcome!
Congratulations your videos are great. I'm from Brazil and I'm translating this text using Google Translate, then if have a mistake I apologize.I learn more with you than with the videos that speak in my own language. I would to know if it is possible to simulate through ANSYS a vehicle (with its concentrated loads on wheels ) to cross the structure and find the worst moments of bending the slab of a bridge. You could make a video on this subject, if you have this knowledge? Thank you.
thank you
Thx!
Can you do a tutorial on 3D beam structure in fire loading? Thanks. Great video!
Hi, Im wondering if it is possible to simulate uniaxial/triaxial cylindrical tests assigning some "rock properties" to the sample in order to obtain the rock mechanical properties like UCS, Friction Angle, Tensile Strenght, etc. It is possible to assign random rock properties to the sample, rocks are heterogeneus, porous, brittle, etc..... Please let me know your comments.
Thanks, Marcel.
Really useful video.... thank you so much...can we validate this manually.
Hi, Thanks you for video
I just wonder that What it use governing equation in Truss ???
You should do slowly when you choose at the endless sub-menu. Please get the experience in next videos.
Hello.
Thank you for this lesson. What do you know about books/practic lessons of ANSYS (like "arhive" for self-studying)?
Finite Element Simulations with ANSYS Workbench 19 - Huei Huang
Hi, nice video and explanation there. Just want to ask about the best simulation tools to study the heat responses of rock cutting. It might be useful if you can advise me this matters.
+ikhwan9455 hi, thats not really in my field. But you could maybe research the software called DIANA FEA. Its more for civil engineering analysis. Good luck!
Hey I'm really new to ansys and this video was absolute gem. But, I didn't understood the cross section work. Is it need to be associated every time? And what about that dimension of 0.05*0.05 you used? Can you please help?
Hello sir, how to get amplitude value at a particular position in the beam along the length like at 0.1m ,. Or how to get amplitude value at 0.1m intervals?
I tried the same geometry without adding the surface body but when i was selecting the type of stress i could not show thing like facor of safty while it appers well in case i add the surface body, anybody have explanation with that ?
can u please tell me how to change the preassure unit from pa to mpa
The mesh looks wrong at the vertices. the mesh doesnt actually join uniformly . does this affect our problem. if i consider a 3-d truss elements?
Why do you have to take a new co-ordinate axis to join the lines in the design modeler? btw great channel!
I have an issue with a similar bridge truss.The points where multiple L section for the bridges comes togather are not like a sigle point. Each sections has an edge there. It is shold be like a single pint welded
Hey, in min 6:19 you're adding Contact Vertices and i'm doing exactly same things, at the bottom program shows me "10 Verticles Selected" but when i click Apply, it gives me "No selection". Do you have some idea what am i doing wrong, what can be my possible mistake?
Any chance you could do a tutorial on a some kind of a simple fordable bridge
Thank you sir , i m follwoing your video lecture to learn ansys, Lectures are most knowledgable and excelent, but sir what is the process to define mesh size, can u tell me ??
Could you tell me how I can perform a dynamic analysis on this? To extract the first few mode shapes and frequenices. I am new to ANSYS and hence encountering a lot of difficulties.
+Rahul Kochar you can use a Modal analysis. In workbench, under analysis systems, drag Modal into the project schematic, and link the cells from the static structural to the modal to share the data, then open modal and find the mode shape and frequencies. Hope this helps! Thanks for watching!
I learn so much from your videos but I am trying to do a wind loading analysis for tipping moment on a tower crane. can you make do us a tutorial about this? thank you :)
Hi. Is there any hand calculation that you could provide? Thank you.
Very helpful are you going to upload any new tutorials?
+Alek Madej hey! I will soon, i have been abit busy lately. Sorry about that. Did you check out my other videos?
Hello. How can I insert a pinned connection between bars?
Can I do this with the student version of Ansys ??
I think you can if you lower the mesh count.
How do I put the profiles under the slab?
hi.yhank you for your education so much. but I have a little question. If you want to use Truss Section you must change the model type to link/truss not beam. you can do it from this address:
Model- Geometry- Line Body- details of Line Body- Model Type- Link/Truss.
thanks.
If the load is applied using the bucket hanging downward. How does that apply in Ansys ?
hello, can you send me solid model of bridge? i can't open your geometry file.
Hi,
I want to ask what are the advantages of using line bodies for beams over the conventional solid bodies? Which will yield a more accurate result?
Cheers!
Line bodies save compute time, which means it solver faster. Sometimes you are not interested in all the details of the body but more the effect it has on the transmission of forces to the other body, so in this case you can use a line body for simplification.
DrDalyO Sure, thanks!
An unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes.
after done everything and go for solution i got this error what is this i don't know please tell me.
Sir, could you please make tutorials on GUI cause it’s really became hard in finding so or please suggest any tutorials to understand GUI.
Have you seen my pluralsight video course? I explain the GUI: www.pluralsight.com/courses/ansys-introduction
Hi DrDalyo, i am having problems modelling a composite structure of a wood frame embedded inside a masonry wall. Do we have to make interfaces between this materials? how do we approach having two different materials when one is inside another and they might interact as the structure deforms. Any suggestions?
Hi, did you finally solve your problems? I'm modeling a composite beam with some tuss connectors and an insulation layer embedded. How to set the interface to be a perfect bond?
kindly tell why there is corss symbol with line body and surface body.
i did the same and it gives me error pivot ........ etc so what should I do?
tararengkyu brother
Hey DrDalyO,
I keep getting an invalid geometry error. Is there a way to diagnose this error(s)?
Hi, you could check the solver output. It would be under the Solution branch, then Solution Information. In the Details window, look for the first option which is Solution Output and make sure its on Solver Output. There you can scroll down and see some more details about the error. Feel free to post it here.
Maybe try redoing the geometry and starting from scratch though, or even try something simpler to start.
Hope this helps!
You could also download the file he used and compare it to yours.
How I can apply more than one force or load?
Hello DrDalyO,
I'm in design modeler attempting to draw a truss frame. I attempt to generate a new line from sketch and once I do it assumes an existing line body that I had generated before with a given cross section, therefore I cannot assign a different cross section to the newly generated line. This frame has components with varying cross sections. How can I generate independent line bodies with different cross sections?
Just set them to "frozen", go search on google.
There are some things unclear to me.
Are beams pin joints or welded on each other and surface? Because if it's pin joint then the beams carry only the axial forces. But in the results there are bendings on beams which means they are not pin joints. So in case the bridge structure would be truss structure, then how is the model changed?
I've seen mech. apdl software is used widely for truss analysis to model truss elements on the other hand for those who claim they are doing truss analysis are actually doing it wrong I think.
Thanks in advance!
+Fırat Ertürk hi, i should probably change the title for this my mistake. They are welded beams. Il probably make another video thats actual trusses, which yes, only take axial force and no bending.
DrDalyO oh great! thanks for your answer and good luck with the new videos!
King regards.
how to download program. help
why did you put Pressure boundary condition on surface.
What type of load are you expecting
hey can i have a solution to manually solve it on paper! please!
U made ansys look so simple
Where did u learn all des things?
In college!
How did you get the stress tool to be available. Mine starts at Deformation. Thanks.
Is it because I'm using the student edition?
I am interested in the safety factor :(
I'm working on a truss problem with structural beams.
what exact version of Ansys do civil engineers use
Could by any version really. Usually depends if they paid for the updates or not, if not then they are stuck with older versions. People are generally on version 13 or higher. Im of course running on 17.
what are the laptop hardware requirements to use ansys 17 smoothly
Any decent computer can run it, however the time to calculate will vary depending on your element, node count and model. Im running a quad core i5 with 8gb ram, and standard nvidia card. You could run on a dual core also. Ansys is very "core" hungry so the more cores you have the faster it will solve. Theres also something called simu cloud i believe where you can run problems on their servers for a fee, and they have tons of computing power.
Thank u so much for this such a great video..it's helpful of many Engineering students......sir..... actually I'm doing a electric go kart..so I have problem with simulation..can I have u r contact details sir .??
you are a bit fast i can't get very well please next time don't be fast when you are lecturing , peoples are not the same capability . thanks for your lecturing and your obedience.
Thank you for your input!
You can change the speed into 0.75x
very helpful
