Steel design - CodeParams

polylouis — Tue, 10 Jan 2023 15:40:47 GMT

Hello everyone,

I am working with RSA 2021 and I succed to launch EC3 calculation like the following steps :

robotProjectPrefs.SetActiveCode(IRobotCodeType.I_CT_STEEL_STRUCTURES, "en 1993-1");

....

// create member type
IRobotLabel steelLabel = robotLabels.Create(IRobotLabelType.I_LT_MEMBER_TYPE, "Parois minces");

IRDimMembDefData frameRobotSteelSectionData = steelLabel.Data;
frameRobotSteelSectionData.Type = IRDimMembDefType.I_DMDT_MEMBER;
frameRobotSteelSectionData.SetDeflYZRelLimit(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Y, 800);
frameRobotSteelSectionData.SetDeflYZRelLimit(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z, 300);
frameRobotSteelSectionData.SetDeflectionYZ(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Y, 1);
frameRobotSteelSectionData.SetDeflectionYZ(IRDimMembDefDeflDataType.I_DMDDDT_DEFL_Z, 1);
frameRobotSteelSectionData.CantileverMode = 0;

IRDimMembParamsE32 rDimMembParamsE32 = frameRobotSteelSectionData.CodeParams;
rDimMembParamsE32.TorsBuckOn = false;
rDimMembParamsE32.LateralBuckling = false;
rDimMembParamsE32.LatBuckMethodType = IRDimLatBuckMethodTypeE32.I_DLBMT_E32_METHOD_GENERAL;
rDimMembParamsE32.BucklingDiagramY = IRDimBuckDiagramE32.I_DBD_E32_NO;
rDimMembParamsE32.BracedY = false;
rDimMembParamsE32.BucklingDiagramZ = IRDimBuckDiagramE32.I_DBD_E32_NO;
rDimMembParamsE32.BracedZ = false;

IRDimThinWalledE32 rDimThinWalledE32 = rDimMembParamsE32.ThinWalled;
rDimThinWalledE32.Active = 1;
rDimThinWalledE32.TypeOfForming = IRDimThinWalledFormingTypeE32.I_DTWFT_E32_ROLLED;
rDimMembParamsE32.ThinWalled = rDimThinWalledE32;
frameRobotSteelSectionData.CodeParams = rDimMembParamsE32;
robotLabels.Store(steelLabel);

I tried to do the same with RSA 2023 but error coming the following line :

IRDimMembParamsE32 rDimMembParamsE32 = frameRobotSteelSectionData.CodeParams;

Do you have any ideas to solve it ?

Thank you in advance,

Regards

Louis

hi @polylouis

have you try setting the preferences.

RobotProjectPreferences Preferences = RobApp.Project.Preferences; int code = Preferences.SetActiveCode(IRobotCodeType.I_CT_STEEL_STRUCTURES, "NF EN 1993-1-1:2005/NA:2013/A1:2014"); if (code != -1 ) { RobApp = null; return; }

Best Regards

hi @Stephane.kapetanovic

unfortunatelly it doesn't work :

Do you have other idea about it ?

Moreover if I comment lines 512 to 525, member type is created but like a timber type and not steel type.. Is it weird isnt'it ?

Regards,

Louis

hi @polylouis

it works with thin walled steel member type for me.

Do you work with version 2023 ?

yes, it works

hi @Stephane.kapetanovic

It works if I call it at first ! 🙂

I have an other question : do you know if nodal displacement views are implemented by APY ?

Thank you in advance,

hi @polylouis

I haven't compared the APIs, the enum IRobotViewDiagramResult Type seems to be the same so only U would be implemented out of the new dispatch possibilities.

Hello,

Please, I want to ask the difference between ParamsE32 and ParamsEC3.
Thanks,

Best regards,

hi @BadrDerouiche

the two interfaces do not have the same properties and methods, one offering more details.
