RSA: I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS - Runtime error / API

[deligny-sa]

Hi,

I have problem with VBA;

RSA blocks at the line : RdimLabelData.SetDeflYZRelLimit I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 300

Here is the example:

Private Sub TEST_Click()

Dim RobApp As RobotApplication
Set RobApp = New RobotApplication

RobApp.Project.Preferences.SetActiveCode I_CT_STEEL_STRUCTURES, "NF EN 1993-1-1:2005/NA:2013/A1:2014"

Dim RLabel As IRobotLabel
Dim RdimLabelData As IRDimMembDefData
Dim RDimMembParams As IRDimMembParamsE32

Set RLabel = RobApp.Project.Structure.Labels.Create(I_LT_MEMBER_TYPE, "TYPE_1")
Set RdimLabelData = RLabel.Data

RdimLabelData.SetDeflYZRelLimit I_DMDDDT_DEFL_Z, 200
RdimLabelData.SetDeflectionYZ I_DMDDDT_DEFL_Z, 1

RdimLabelData.SetDeflYZRelLimit I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 300
RdimLabelData.SetDeflectionYZ I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 1

Set RDimMembParams = RdimLabelData.CodeParams

RdimLabelData.CodeParams = RDimMembParams
RobApp.Project.Structure.Labels.Store RLabel

Set RLabel = Nothing

End Sub

Thanks for your help

hi @deligny-sa 

The criteria for member deflection from live loads are not set by the SetDeflYZRelLimit method of the IRDimMembDefData interface, as they are for final deflection and checkboxes.

Instead, they can be set by the RelLimitdeflUz property of the IRDimMembParamsE32 interface.

'[...]
  Dim RLabel As IRobotLabel, RdimLabelData As IRDimMembDefData, RDimMembParams As IRDimMembParamsE32
  Set RLabel = RobApp.Project.Structure.Labels.Create(I_LT_MEMBER_TYPE, "TYPE_1")
  Set RdimLabelData = RLabel.Data
 
  With RdimLabelData
    .SetDeflYZRelLimit I_DMDDDT_DEFL_Z, 200
    .SetDeflectionYZ I_DMDDDT_DEFL_Z, 1
    .SetDeflectionYZ I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 1
    
    Set RDimMembParams = .CodeParams: RDimMembParams.RelLimitdeflUz = 300
    .CodeParams = RDimMembParams
  End With
  RobApp.Project.Structure.Labels.Store RLabel
'[...]

You can refer to the example titled: APi - steel design - Activate deflection limit

Thank you, it's perfect.

Hi,

I get the total arrow with "RDmDetRes.UZ"

How to get the instant arrow?

I can't find the code.

Thanks for your help

hi @deligny-sa 

Are you planning to use a set of combinations that exclude the permanent load cases? If so, the same approach can be applied in a second phase.

Best Regards

Hi,

I wrote the code to deduce the permanent arrow from the total arrow

it works.

Thanks

Hi,
I am working in cpython3,
I found similar problem, where the z deflection from live loads is not filled.
The Cpython3 code i wrote is below:
lbl = IRobotLabel(labels.Create(IRobotLabelType.I_LT_MEMBER_TYPE, "Adj_Member"))
lblData = IRDimMembDefData(lbl.Data)
lblData.Type = IRDimMembDefType.I_DMDT_MEMBER
lblData.SetDeflYZRelLimit(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z, 600)
lblData.SetDeflYZRelLimit(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 600)
lblData.SetDeflectionYZ(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z, 1)
lblData.SetDeflectionYZ(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 1)

Thanks in advance.

Hi @Stephane.kapetanovic 
I have read and already tried to modify to cpython3 code, below is the code:

RDmServer = IRDimServer(robapp.Kernel.GetExtension("RDimServer"))
RDmServer.Mode = IRDimServerMode.I_DSM_STEEL

lbl = IRobotLabel(labels.Create(IRobotLabelType.I_LT_MEMBER_TYPE, "Adj_Member"))
lblData = IRDimMembDefData(lbl.Data)
lblData.Type = IRDimMembDefType.I_DMDT_MEMBER
lblData.SetDeflYZRelLimit(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z, 600)
#lblData.SetDeflYZRelLimit(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 600)
lblData.SetDeflectionYZ(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z, 1)
lblData.SetDeflectionYZ(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z_FROM_LIVE_LOADS, 1)
param = lblData.CodeParams
param.RelLimitdeflUz = 500

However, 500 is not generated at all in my RSA.

[Stephane.kapetanovic]

did you forget something ? 

param = IRDimMembParamsE32(lblData.CodeParams)
param.RelLimitdeflUz = 500
lblData.CodeParams = param
