In plane deformation value

[Anonymous]

Hi,

how is it possible to show in plane deformation? I need to show deformation in X plane and in Z plane!?

When I select "exact deformation for bars" I get this:

And when I enter in "axe 2 view" I get this:

Kind regards!

Very needed but still Not possible. What you see on any view ,even if it is a plane view ,is the value of the resultant global defrormation.

Thank you. This is what I figured out but hoped, maybe, there's a way around.

I found the nodes that have max and min deformation values and inserted the table in printout but for sure it would be more convenient (and more professional) to insert a graphic representation of the structure.

.....very sad.....I do not understand that something so obvious is missing.  

Kind regards!

PS: Do you have some tips on how to create printout composition? What I realized is that sometime, somehow screenshots rescale without logical explanations!

It still also happens here to and has always happenned!! It gets better the more RAM you have. But I have 32gb and in a printout that has many screenshots it gets worse.

I always print to pdf , so I can check the output. If there is something wrong I go to that particular screenshot and edit it. Sometimes just opening and closing the edit session solves the problem

Thank you. I thought that I was doing something wrong.

I have the same workflow as you. Unfortunately, even when printing to pdf takes some time when there are many screenshots involved. I also experience software crashes.

Hope it gets better, but honestly I doubt it.

The whole principle of making reports in ARSA is very obsolete and takes to much working hours.

Hi @Anonymous ,

In fact , there is a way to make RSA show the displacements on each of the 3global axes. I have thought about this sometime ago , but never really needed to execute it.

But if you really need to show it graphically , maybe it is worth the extra work , which probably will be more easily done with the aid of an API.

I modelled a simple bar frame as an example. The "trick" is to attach tiny panels to each bar node . These tiny panels shall have a material that is weighless, with very low" E"(small stiffness) and/or with a very small thickness. For this example I just made it with 1mm thickness ,concrete.

Attach them to the bar nodes with rigid links

Then Using "Maps..." results on "Principal" tab ,you are able to get the displacements on each of the 3 global axes directions

Still using the Maps... dialog you can set to have the above deformed shape using the "Deformation" tab.

Then you can use it to also show the global X deformation

Probably Robot will report an instability type 3 warning , which can be ignored.

Test model attached

Thank you so much for your time.

I will try this step by step although I think that it should've been something implemented 20 years ago.

Kind regards!
