how to get joint displacement as step-by-step in sap2000 by using SM toolbox

I run sap2000 model using pushover analysis so I want to get displacement as step-by-step displacement what i got only as envelopes not step-by-step.

so I need code for SM toolbox to be used to get step-by-step displacement.

@Ali,

I recommend you post your request on the dicussion board for SAP + Matlab Toolbox, here, or at SM Toolbox Instructions in the File Exchange. Maybe you will get a response from the author or from others who uses that toolbox.

Hi Ali,

To obtain step-by-step joint displacements in SAP2000 using the SM Toolbox, you can use the following MATLAB code snippet. I assume you have already set up your SAP2000 model and performed the pushover analysis.

SapObject = actxserver('SAP2000.SapObject');
% Start Sap2000 application
SapObject.ApplicationStart;
Sap = SapObject.SapModel;
Sap.File.OpenFile([FilePath,'.sdb']); % Open your model
Sap.Analyze.RunAnalysis();
% Get the number of steps in the pushover analysis
numSteps = Sap.Results.NumberOfSteps;
% Initialize arrays to store displacements
jointDisplacements = zeros(numSteps, 1);

% Loop through each step to get joint displacements
for step = 1:numSteps
    % Get joint displacement for a specific joint (e.g., joint 1)
    [displacement, ~] = Sap.Results.JointDispl('Joint1', step);
    jointDisplacements(step) = displacement;
end

% close Sap2000
SapObject.ApplicationExit(false());
SapModel = 0;
SapObject = 0;
