P. To display time history graphs

To display data of time versus displacement, velocity, or acceleration, use the following procedure.

Time history plots are only available for STAAD.Pro models with time history loads.
  1. Select the time history response plot you want to view:
    To view… Select…
    Displacement data the Layouts > Displacement tool in the Dynamics group
    Velocity data the Layouts > Velocity tool in the Dynamics group
    Acceleration data the Layouts > Acceleration tool in the Dynamics group
    A set of three plots opens.

    If you do not have any node groups defined in the model, you will asked if you want to define any now. If you opt to not create any now, you must select the Analytical workflow to define node groups.

  2. Either:
    To graph data for… Select…
    a single node the node in the graphical view
    a node group that defines a floor the name of the node group in the Select Groups dialog
    ヒント: You can use the Group tool in the Attributes group on the Select ribbon tab to display the Select Groups dialog.
    Selecting a node group will display calculated average time history results for the desired response. This feature can be used to generate floor spectra at each floor level in a structure which can then be used as input for other dynamic analysis such as analysis of vibrating machinery existing on the floor.
  3. To select the global direction of action displayed on the y-axis for a plot:
    1. Right-click on the graph and select Diagrams from the pop-up menu. The Diagram dialog opens.
    2. Select global direction for the action. More than one global direction can be displayed on a plot.
    3. (オプション) Click the color block beside a global direction to specify a different color for the plot.
    4. Click OK.
  4. To change the x-axis of a graph to display frequency instead of time:
    1. Right-click on the graph and select Diagrams from the pop-up menu. The Diagram dialog opens.
    2. Select Frequency Domain and then click OK.
    The graph updates to display frequency. STAAD.Pro transforms the time-domain to frequency-domain by means of the fast Fourier transform (FFT) method.
  5. (オプション) To save the current set data to an external file:
    1. Right-click on the graph and then select Save data in a text file from the pop-up menu. A Windows File Open dialog opens.
    2. Select a location to save the data.
    3. Type a File Name and then click Save.
    The plot data is saved in a plan text file (file extension .txt).
  6. You can use pictures of the graph in other reports or external programs by right-clicking on the graph and selecting:
    Select… To…
    Copy Picture copy the graph to the Windows clipboard
    Take Picture save the image for use in reports for later use. A Picture dialog will open for a label and caption. Click OK to save the graph to the report Picture Album.
