18. Select Output File
Select phase to be viewed
![Page 4: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/4.jpg)
Choosing “incremental
displacements” allows one to see the
displacement per calculation step,
helping visualize an eventual failure
mechanism
19. Deformations
Select orientation of displacement
Deformed mesh is displayed by default upon
opening program

20. StressesView effective stresses or total stresses (active pore
pressure + effective stress)
![Page 6: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/6.jpg)
21. Viewing Tabular Results
Table output can be viewed for specific areas of concern
![Page 7: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/7.jpg)
22. Flexible Footing
Instead of prescribed
displacement a load will be imposed on the soil yielding a displacement later
Save as under a different
name

23. Modify the GeometryChoose to
create a beam element
![Page 9: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/9.jpg)
24. Modify the Boundary Condition
Apply a traction to the boundary simulating the
applied force on the footing
![Page 10: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/10.jpg)
25. Assign Materials for the Footing
Select “New…” beam
material
Input material properties as with soil layer
Beam Material Properties
![Page 11: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/11.jpg)
Drag n drop footing
material onto the beam element
26. Assign Materials cont.

27. Generate Mesh
![Page 13: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/13.jpg)
28. Initial Conditions
Regenerate initial stresses
![Page 14: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/14.jpg)
29. Calculations
Name the phase
![Page 15: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/15.jpg)
30. Calculations cont.
Apply a multiplier of 350* to the traction load A
Accept default for
parameters
*note: (350) x (1kN/m2) x (p)(1)2 ≈ 1200kN
Check that points are still selected for
curves
![Page 16: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/16.jpg)
31. Output
Double click the beam in the out put
program to view bending moments or displacements in the
beam
![Page 17: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/17.jpg)
32. Curves Program
Select new chart upon
entering the program for the
first time
![Page 18: Plaxis Tutorial 03](https://reader036.fdocuments.us/reader036/viewer/2022081413/54724b83b4af9fcf2f8b4633/html5/thumbnails/18.jpg)
33. Generating a Load-Displacement Curve
Choose “Displacement
”
Select point “A” assigned in
the calculations
phase
Select Uy and check “Invert sign” for negative vertical displacement of
footing @ center
Choose “Multiplier”
Choose to plot the loading multiplier
along the y-axis

34. Curve Output Once generated, curve presentation
can be altered using chart and curve
settings
