1. Axial Force/Stress/Strain Diagrams

Click N, and select "Force F" on the Dropdown menu (on the left of the N button), to see the Axial Force Diagram. You may take the picture below.

 

Example1_27

 

The Axial Force Diagram is out of Scale. Click the "Zoom All" button ZoomToFit to automatically scale the Diagram.

 

Now the result should look like this, which is much better. We see that the Force of Element 13 (Member CF) is -0.59 kN, the same as the one we found with Hand Calculations.

 

Example1_28

 

Select "Stress σ" on the Dropdown menu and click N to see the Axial Stress Diagram.  If the Axial Stress Diagram is out of Scale, Click the "Zoom All" button ZoomToFit to automatically scale the Diagram. You should take the following picture.

 

Example1_29

 

Again, select "Strain ε" on the Dropdown menu and click N to see the Axial Strain Diagram. If the Axial Strain Diagram is out of Scale, Click the "Zoom All" button ZoomToFit to automatically scale the Diagram. You should take the following picture.

 

Example1_30

 

Although the strain is in Permille units (‰), it appears that 2 decimal places are not enough to express it the right way. You may want to increase the number of decimals. To do that, visit the Units form and set the Decimals for strain from 2 to 4. Then you will get more accurate strain values. The Strain Diagram is plotted correctly and is not affected by the number of decimals used. Only the shown values are affected.

 


 

2. Axial Force/Stress/Strain Color Plots

Click CT_Color6, and select "Force F" on the Dropdown menu (on the left of the N button), to see the Axial Force Color Plot. You may take the picture below.

Example1_31

 

Click the "Zoom All" button ZoomToFit to automatically scale the Diagram. Now the result should look like this. Note that the Color Plot is drawn on the Deformed state of the Model, by default. This is a setting which can be changed in Settings.

 

Example1_32

 

Select "Stress σ" on the Dropdown menu and click CT_Color6 to see the Axial Stress Color Plot.  If deformation shown on the Axial Stress Color Plot is out of Scale, Click the "Zoom All" button ZoomToFit to automatically scale the Diagram. You should take the following picture.

 

Example1_33

 

Again, select "Strain ε" on the Dropdown menu and click CT_Color6 to see the Axial Strain Color Plot. Click the "Zoom All" button ZoomToFit to automatically scale the deformation on the Diagram, if needed. You should take the following picture. Note that we have changed the Decimals from 2 to 4 to depict strain values better.

 

Example1_34

 


 

3. Deformation

Click Deformation3, to see the Model Deformation. If the Deformation is out of Scale, Click the "Zoom All" button to automatically scale it. You should take the following picture. The program reports also the Deformation magnification, in our example x2859.51.

 

Example1_35

 

You can adjust scaling yourself by using the +/- buttons at the top left of the picture. If you click the "+" button a few times, you may get a picture like the one below where the magnification factor is now x7148.77.

 

Example1_36

 

See above that you can get the deformation values on screen, if the mouse pointer hovers over an element.

 

IMPORTANT: The values that are given on screen are the dX, dY, dx and dy displacements of the corresponding point of each element.

dX and dY are the X- and Y- displacements of a point, respectively, in Global axes. For example a positive dX means displacement to the right, while a positive dY means displacement upwards.

dx and dy are the x- and y- displacements of a point, respectively, in Local Element Axes, where x is defined from the Start Node i and the End Node j of the Element and y is perpendicular to it.

 


 

4. Free Body Diagram (FBD)

Click F, to see the Free Body Diagram of the Model. The Free Body Diagram shows the support reactions on screen and also the calculations of the equilibrium of the Model.

We see that the support reactions are the same as the ones found with Hand Calculations.

 

Example1_37

 

Note that if you hover the pointer over an Element, you can read the corresponding Axial Force at that point, as shown below. The Element End Forces are also given on screen, for the specific Element.
