ANSYS 2020 Tutorial: Reinforced Concrete T-Joint

ANSYS Workbench V2020 R2 Tutorial for a Reinforced Concrete T-Joint using CPT215 Elements with Reinforcement type option in Mechanical.

***NOTE: You must use the same version of ANSYS 2020 R2. There are reports that newer versions of ANSYS no longer work with this tutorial.***

I demonstrate how to use the latest modeling technology to simulate a reinforced concrete T-joint using Ansys Workbench version 2020 R2. In this example The simulation results will be compared to that of actual experimental results.

This tutorial we will go over importing the geometry, setting boundary conditions where we will fix the column in place and apply a displacement of 80mm downwards at the end of the beam, and finally go over viewing the results which include the homogenized tension & compression damage by using APDL commands:

PLNSOL,MPDP,TOTA: Homogenized total damage (TOTA)
PLNSOL,MPDP,COMP: Homogenized tension damage (TENS)
PLNSOL,MPDP,TENS: Homogenized compression damage (COMP)
PLNSOL,MPDP,RW: Split weight factor (RW)

We will also be using CPT215 elements (Drucker-Prager Microplane Model) and the Reinforcement Type option within Mechanical to model the rebar. This is an improvement compared to my previous video which uses SOLID65 elements and REINF265 commands.

The is absolutely fantastic. You're one of the best FEA resources on YouTube!

great job, thank you very much for sharing. For your information, I repeated this simulation with version 2023 R1 and the idea provided in tutorial works. Results are however slightly different - in the first phase it is almost identical as Ansys Inc., then, after reaching peak force reaction the softening happens faster (results go belowe experimental curve), however it is still satisfying. I will play later with analysis settings and check the correlation. Thanks once again!

Thank you! I started to study ansys, everything turned out like you did. Thanks again for your work, we are waiting for new videos

[carelesseagle]

Just wanted to say, Amazing work! Thank you for your amazing commentary and attention to detail. It has helped me a lot!

[willywirawan]

Best quality of ansys tutorial on youtube!!

[wangjeerneeful]

Thank you Dr. Dalyo for your useful videos

[ΑθανάσιοςΓιαννακόπουλος-ξρ]

You would be the ideal Matlab instructor for FEM!!!

[nhatvule]

Thank you for coming back. Your tutorial is the best.

Thank you DrDalyO. I have been waiting from 2016!
Great Man!! You are amazing! Big thanks!!

[adrianviloria]

thank you! I have been waiting for this!

Hi i was rrying to find any info abit the parameters that appear in 10:23 but cant find any, do you have any relevant info or point me in the direction? Great video

[hopkinsjr]

Your videos are just fantastic.
It would be great if you did a video om the explicit dynamics environment. Maybe an impact tets

Thanks for your model, it's really inspiring. I've one question: ¿is this model able to simulate cracking and crushing? It seems that Drucker-Prager concrete is a kind of plastic material since there's not a decrease in its stress when tension strength is reached. What I mean is, is there a way to combine steel reinforcement (via REINF264 elements) with cracking-crushing concrete (via SOLID65 elements with CONCRETE model)? Thanks in advance and br!

hi Dr Dalya can you make tutoral nonlinear buckling analysis in ansys workbench 2020

[djerradabderrahim]

Hello, Please can we use the same simulation process but using other analysis type such as Transient analysis or Random vibration analysis ?

[williamandarohondro]

Nice Master... thank you for the tutor

[sahinsozen]

It is wonderful as usual. Thanks a lot. Can CPT215 be used for masonry?

[rzgarasadd]

fantastic sir, i need more about rcc members, but could you tell me whic one better software Abaqus or Ansys ?

[allaf]

Thank you ... How can i add crack/crush diagram to the results ?

What's the purpose of the symmetry and how do you decide the face to pick for it.
