I have just carried out a static study on a 50x50x30 square tube metal structure but I manage to get the result because my PC has crashed.
Well, I'm trying to determine the choice of tube to use for this structure, whether it's a 2 or 3mm thick tube.
This structure will be used for a ventilated façade that it will be fixed on the wall with a console so that the sandstone we are going to use it will be fixed on the structure with clips at the 4 corner.
The dimension of the stoneware is 1200X600 (mm) and the weight is 32 KG per 1 square meter
The tube material is S235JR
Limit the areas where I apply the stress that it will undergo the structure
NB: I marked the front with a red color (where we will fix the clips)
NB: the back face is to put the constraint of fixing the structure on the wall (always I talk about the limit areas with the dividing line tool.
Attached is the structure with the study I have just carried out. Please is there anyone who can help me.
There are quite a few basic errors in your model which should be simplified anyway before going any further.
But before answering you on the points of improvement to be made: would you be so kind as to close your previous request of December 25, 2020 https://www.lynkoa.com/forum/solidworks-simulation/comment-realiser-une-etude-de-simulation-statique?page=1#answer-1073634 by designating the answer that suits you.
It's been a long time but really I wouldn't be able to solve all the problems you mentioned to me about my last request (Static simulation). I chose to work on a single module to simplify the problem a little.
I carried out the study by applying a force of 3000N (Force generated by the mass of the sandstone ( knowing that a square meter weighs 30 KG) I worked with the beam and I took the four corners as a point of fixing on the wall so I took the six connection points between the tubes as the point of application of the load)eliminates the plates and the angles and the clips that will carry the stoneware).
I end up with a result and I wouldn't be able to read it correctly.
Please, Can you help me interpret the results (what does STRMAX mean (the resulting effort constraints); " the value 6.377e+05 knowing that the yield strength of the chosen material is 2.350e+08.
Will the structure deform by 5.8 mm maximum.
How can I know if the 50x50x3 structure is supported by the load. Can I play with the thickness to minimize the cost of the project ?
NB: on the report the thickness of the square tube is 4 mm but in reality it is 3mm because I can't find a tube of thickness 4 in my list. I choose 50x50x4 and I modified the sketch.
RQ: As I told you, I'm a beginner in solidworks and especially in simulation. Maybe all my study is wrong. but still, you have to try to learn.
Apparently, the loads exerted by the sandstone slabs are applied to the very place where the fixed areas of the structure are located, supposedly linked to a totally rigid "frame". As a result, the tubes of the structure are not stressed at all by these loads. Only gravity acting on the metal tubes of the structure has an effect, of course extremely small...
Hence a maximum displacement of 5,832e-3 mm, or 5.8 micrometers! Suffice to say nothing...
And a normal bending stress of 6.377e+5 Pa, or 0.63 MPa, to be compared with the yield strength of 235 MPa. Here too, insignificant. To conclude: the structure is not solicited.
In the attached pdf, some elements for a basic static study...
I read your pdf very carefully, and I imagine that our requester @wissem86ayed did the same... That being said, his last questions show that there are still points to be clarified to deal with his simulation: "I am a beginner in Solidworks and especially in simulation matters", or "you have to try to learn".
My ambition is not to denigrate his study or your answer, but to propose a few simple ways to achieve a valid result that illustrates the approach. And to comment on some of the results to understand how his model behaves. He is then free to integrate connections to supports, more elaborate connections or loading, other meshes or solvers, in a different context. Kind regards...
Thank you Pierre for all your advice and efforts to help me. Thank you very much, I wish you success in your professional and social life.
To conclude: While our structure is subjected to a very low stress of 3 MPa and a very low deformation of 0.016 mm. so we can use a 50X50X2 square tube instead of a 50X50X3 tube.
As for your experience, do I have to do the same study on the structure with 2mm thick tube where it certainly supports the loads.
A silly little remark, but it seems to me that it is a terrace that you are designing.
The dead weight of the slabs is generally more or less negligible compared to what will be laid on the slabs.
I don't work in the construction industry but it seems to me that it is at least 250kg/m2 of load that must be taken into account (i.e. 4 to 5 people per m2 or a few tens of cm of heavy snow).
It will flex a little more by adding this load to the masses of the slabs + tubes.
In this case, it is the ventilated façade of a building, with in principle a load-bearing wall, an insulating layer, and a cladding consisting here of sandstone slabs arranged vertically on a metal structure fixed to the wall.
m.blt: That's exactly what you just showed on the image in your last comment but in our case we added a primary structure because the load-bearing wall is in relief (it is not coplanar). What I am trying to determine is the thickness of the tube (either we work with 50x50x3 square tube or 50x50x2 tube) guaranteeing that it supports.
In my opinion I can work with tubes of thickness 2 because on the graph there is no part stressed more than the limit of elasticity of the chosen material "235 MPa" (only small slice at the corner which is colored red).
Attached is the report of my last study and the results I obtained
The simulation I have proposed is based on a very simple model, taking into account only gravity and rudimentary connections, and is not enough to validate your design. Its only ambition is to illustrate the simulation approach.
The building standards and rules in the real world are much more demanding, and take into account climatic (wind), thermal, seismic aspects, and in your case the solutions for connecting to the load-bearing wall and fixing the slabs, before authorizing such façade construction systems.
A search on the internet will allow you to find the websites of manufacturers specialising in the field and organisations responsible for certifying this type of work.
