Hello,

I have a problem while generating moving loads.

In fact, when i generate a load, i dont understant how the total reaction is determined by the software.

In the example enclosed, i have generated a moving load called "eeeeeeeeeee".

In theory, the reaction is: R = 50 x 1 x 1 = 50 kN

In fact the reaction is 100 kN (twice more)

Therefore, i don't understand the first and the last résult (252 kN and 358 kN).

Thank you for helping me.

Hi,

I made some other tests with a single slab structure. Here's what i found:

- For a load of 150 kN/m² applied on 1.00m x 1.00m, the reaction should be 150 x 1 x 1 = 150 kN ==> Results OK
- For a load of 150 kN/m² applied on 1.00m x 0.50m, the reaction should be 150 x 1 x 0.5 = 75 kN ==> Results OK
- For a load of 150 kN/m² applied on 0.50m x 1.00m, the reaction should be 150 x 1 x 0.5 = 75 kN ==> Results OK

There is no problem with the reactions.

In fact the problem appears when you have a "frame structure".

I've done the same exercice and here's what i found:

- For a load of 150 kN/m² applied on 1.00m x 1.00m, the reaction should be 150 x 1 x 1 = 150 kN ==> Reaction of 300kN (twice more)
- For a load of 150 kN/m² applied on 1.00m x 0.50m, the reaction should be 150 x 1 x 0.5 = 75 kN ==> Reaction of 150kN (twice more)
- For a load of 150 kN/m² applied on 0.50m x 1.00m, the reaction should be 150 x 1 x 0.5 = 75 kN ==> Reaction of 150kN (twice more)

I don't understand...

You'll find the files enclosed (saved without results).

Hi,

Thank you very much!

It works perfectly.

Now, is there any way to do this (chose the object for the application of the moving load) trough API (VBA)?

While creating the moving case you wrote:

Set Cas = Robapp.Project.Structure.Cases.CreateMobile(Robapp.Project.Structure.Cases.FreeNumber, "Moving Load Case", I_CN_PERMANENT)

' What have i to add? I found this

Cas.ApplicationPlaneType = I_MCAPT_SELECTION

The problem is that i don't manage to select a panel to attribute...

Is it possible to have some help please?

This should work:

```Cas.ApplicationPlaneType = I_MCAPT_SELECTION
Cas.ApplicationPlaneBars = "3"
```

but it does not.

We need to check it

Hi,

I think I found the solution.

In fact, the lines you wrote apparently have to be after the attribution of a case at the end, as follow:

Set Cas = robot.Project.Structure.Cases.CreateMobile(505, nom_charge_roulante, I_CN_PERMANENT)

'''' Set route ...

''''''Set Fac ...

''''' Set Vlabel ....

''''' Set Vdata ....

'And then:

Robot.Project.Structure.labels.Store VLabel

'/!\ The lines you wrote seem to have to be written after this line, at the end of the case /!\

/!\ The line cas.vehicule = moving_load_name disable the selection, you can see it by doing "step by step" execution in VBA /!\
Cas.ApplicationPlaneType = I_MCAPT_SELECTION
Cas.ApplicationPlaneBars = "3"

It's kind of weird, but it seems to work...

Is it possible for to test it by your own and tell me if it works on your side?

Thank you,

VE

Virgile,

You are right! I  tried after Route definitiion...

After Cas.Vehicle  - it works !
