Bonjour j'ai un petit problème lors de mon dimensionnement barres acier, je remarque que les calculs à l'ELS ne me donnent aucun résultat.
Quelqu'un a une solution à ce problème ?
Hello, I have a little problem when I design steel bars, I noticed that the calculations ULS don't give me results.
Anyone to help me ?
Sorry I want to say Robot doesn't want to calculate my SLS combinaisions
Why ?
Maybe because the type is SimpleBar ?
I saw if I change with Column or Beam it will calcultate.
Is there something to change ?
Maybe because the type is SimpleBar ?
This type hasn't got the SLS limits defined.

yes I know this
But When I do it
I really don't have same ratios
For example, I change my combinations SLS to ULS.
And then I obtaine for my "SLS", maximum ratios = 0.27
I thought if I add a condition on bars and change the name of bar by bar2
It will give me the same ratios but really depend on which conditions I choose
For a condition on displacement of nodes, I have a maximum ratio = 0.49
Where is the link ?
For a condition ON FINAL DEFLECTION OR DEFELCTION FROM LIVE LOADS, my max ratios are 0.04
Someone have a solution to explain me
I am afraid to do not understand you clearly but ULS design is performed on ULS combinations, SLS on SLS combinations.
Program recognizes combination types.
If it is not the case please explain and send us example.
Ok It will be very easy
1st CaseSLS1
First I create SLS combination : and all members are BAR, so no results when i want to see Verification design.
2nd CaseULS1
Second I tried to convert SLS to ULS but I don't change my combinations, i have results at Verification design and max ratio is 0.19
For my combinations 14to20By2 23 24to30By2 max = 0.19 Second file ULS (my ULS are my SLS but i just changed my combination type)
For my combinations 14to20By2 23 24to30By2 no results at design steel members SLS
Third I want to know how to stay SLS and found the same ratio than my second file ?
You said to change BAR, can you do it with my first file and tell me if you found the same ratios
If yes, you will resolve my problem and send me the file.

To obtain the results of SLS verification results you need to :
1. Define SLS combination and use them in the verification
2. Set SLS limits in the parameters assigned to elements of a model
2nd CaseULS1
Second I tried to convert SLS to ULS but I don't change my combinations, i have results at Verification design and max ratio is 0.19
For my combinations 14to20By2 23 24to30By2 max = 0.19 Second file ULS (my ULS are my SLS but i just changed my combination type)
For my combinations 14to20By2 23 24to30By2 no results at design steel members SLS
There are no SLS results as you need to follow the points described above.
The correct workflow for ULS and SLS verifications is:
1. Create ULS combinations (usually they have load factors larger than 1) and use them for ULS verification (type their numbers into ULS limit states load case selection field in the Calculations - CSA dialog)
2. Create SLS combinations (usually they have load factors equal to 1) and use them for SLS verification (type their numbers into SLS limit states load case selection field in the Calculations - CSA dialog)
3. Set SLS limits in the parameters assigned to elements of a model
4. Run verification
Third I want to know how to stay SLS and found the same ratio than my second file ?
You can in addition to existing SLS combination create new ULS ones (if you want they can be exactly the same as the SLS ones). Then you need to assign SLS limits to elements of the model. Afterwards type the ULS combinations numbers in the ULS case selection field and SLS combinations into SLS one. Finally press the verification button.
