Can anyone give us a tip in meshing this structure. File is attached. Control Model (RC Frame)

Thank you in advance!

Hi

Also see here for a tutorial showing the way we should model concrete structure and failure:

All the best and kind regards

I have uploaded some images of our model. The second and third picture is an image of the model with the reinforcement and without the reinforcement, respectively. Base on our own judgement, we think that the reason why meshing the said model is hard because of the third image where areas where the reinforcements are supposed to be are hollow which makes it hard for ansys to mesh. 

We are to mesh and analyze the beam column joints of the structure and we were actually advised to divide the model so that we can precisely mesh the beam column joints and with smaller element size while the other parts of the model can be meshed with bigger element size, but we find it hard to that. 

In addition, we can't seem to find the "Model Type" under properties section to use the REINF264 element. Thank you in advance.

Hi

 

The reinforcements (type) need to be modeled as line bodies, and then we can choose reinforcement type – the tutorial I show that it is 2021 R1 so the reinforcements are not available in 2020 R1 (as you also noticed) – one would need to upgrade to a newer version to use them (reinforcements) inside Mechanical - I would suggest to upgrade to at least 2022 R2 - any older models clike 2020 R1 can be opened with a newer version (not with an older though).

I have actually now upgraded my ansys, and have tried the reinforcement type to my rebars and it worked, can the stirrups and ties be designed as line bodies too then set as reinforcement later? And i would also like to add if you have any tutorial on how to add retrofitting techniques such as steel plate jacketing the correct way, especially when it comes to the bolts.

Thank you in advance.

Does this mean that we cannot mesh it the way it is now, or we can still do so in this version but it will be difficult? Can we also open this model in upgraded versions of ansys?
