SAP2000 API MatLab - Setting restraints

[MathiasC]

Hi,

does anybody know, why the following part of my codes doensn't work?

%% Add Restrains to Point K1
U1=true;
U2=true;
U3=true;
R1=true;
R2=true;
R3=true;
Restraint=[U1,U2,U3,R1,R2,R3];
ret = SapModel.PointObj.setRestraint('K1',Restraint)

I get the following MatLab error:

??? No appropriate method, property, or field setRestraint for
class Interface.AF6944AC_37D3_42A0_8C32_A8DE5E501EF0.

Thanks for your help
Mathias

hi! Mathias

Try this:

PointName1 = ' ';
PointName2 = ' ';
Restraint = logical(zeros(6,1));
for i = 1 : 6
Restraint(i,1) = true();
end
[ret, PointName1, PointName2] = SapModel.FrameObj.GetPoints('K1', PointName1, PointName2);
ret = SapModel.PointObj.SetRestraint(PointName1, Restraint);

Regards

Dear ricbus,

Solved!!

Thanks for your help!

Hi guys,

I am using Matlab2017a to interact with Sap2000. Now that my model is built, i want to add a load case for response spectrum. In the CSi OAPI help documentation, the function to do so is:
SapObject.SapModel.LoadCases.ResponseSpectrum.SetCase

I tried to call the fonction with the following syntax :
LoadCases = NET.explicitCast(SapModel.LoadCases,'SAP2000v18.cLoadCases');
ret = LoadCases.ResponseSpectrum.SetCase('Spec');


It keeps giving me errors that the syntax for this function isn't appropriate:
Error using MatSap (line 357)
No appropriate method, property, or field 'SetCase' for class 'SAP2000v18.wCaseResponseSpectrum'.

Can you help me with the syntax in matlab to Add a load case ?

Hi Ushaann

NET.explicitCast refers to Visual Basic, therefore it does not run. Remove it.

Hello ricbus,

Actually the newest CSi OAPI documentation exemple for matlab uses it for ALL its functions !
Here is what a part of their example looks like:

%% create SapModel object
SapModel = NET.explicitCast(SapObject.SapModel,'SAP2000v18.cSapModel');

%% initialize model
ret = SapModel.InitializeNewModel;

%% create new blank model
File = NET.explicitCast(SapModel.File,'SAP2000v18.cFile');
ret = File.NewBlank;


%% define material property
PropMaterial = NET.explicitCast(SapModel.PropMaterial,'SAP2000v18.cPropMaterial');
ret = PropMaterial.SetMaterial('CONC', SAP2000v18.eMatType.Concrete);

%% assign isotropic mechanical properties to material
ret = PropMaterial.SetMPIsotropic('CONC', 3600, 0.2, 0.0000055);

%% define rectangular frame section property
PropFrame = NET.explicitCast(SapModel.PropFrame,'SAP2000v18.cPropFrame');
ret = PropFrame.SetRectangle('R1', 'CONC', 12, 12);


%% define frame section property modifiers
ModValue = NET.createArray('System.Double',8);
for i = 1 : 8
ModValue(i) = 1;
end
ModValue(1) = 1000;
ModValue(2) = 0;
ModValue(3) = 0;
ret = PropFrame.SetModifiers('R1', ModValue);


%% switch to k-ft units
ret = SapModel.SetPresentUnits(SAP2000v18.eUnits.kip_ft_F);


%% add frame object by coordinates
FrameObj = NET.explicitCast(SapModel.FrameObj,'SAP2000v18.cFrameObj');
FrameName1 = System.String(' ');
FrameName2 = System.String(' ');
FrameName3 = System.String(' ');
[ret, FrameName1] = FrameObj.AddByCoord(0, 0, 0, 0, 0, 10, FrameName1, 'R1', '1', 'Global');
[ret, FrameName2] = FrameObj.AddByCoord(0, 0, 10, 8, 0, 16, FrameName2, 'R1', '2', 'Global');
[ret, FrameName3] = FrameObj.AddByCoord(-4, 0, 10, 0, 0, 10, FrameName3, 'R1', '3', 'Global');

My name is Waldy Torres, studen of master degree in Mechanical computational, i am trying to converse SAP2000 with Matlab, for optimization free form, but the help the commands of OAPI SAP it not works to matlab, mainly all commands get, Count.... the next message is shown
"No appropriate method, property, or field 'Count' for class 'SAP2000v19.wFrameObj'."
I want to extract total number of Frames, coordinates x,y and z, joint i, joint j, labels, and all result how displecement , Stress, but I do not get any properties again.
Do you can to help me ?
how the commands of OAPI SAP they work?
Do you have any example ?
