The frame appearance is adjusted based on the selected verification methodology.
- Verification according to the factor of safety, or the theory of limit states - the last column in the table allows for inputting the design coefficients, which multiply the calculated forces. These forces are displayed on the desktop and are updated for every change of data and setting in the frame.
- Analysis according to EN 1997 - the last column in the table allows for specifying whether the load acting on a structure is considered as secondary one. This is explained in more detail in section "Load combinations".
- Analysis according to LRFD - in this case the last column is not displayed.
To verify the external stability a fictitious structure (wall) is created and further subjected to the verification analysis. A fictitious wall consists of the structure front face, a line connecting end points of individual nails, a vertical line constructed from the end point of the first nail up to the terrain depth and from the end point of the last nail up to the structure depth (thus the bottom edge of a fictitious structure is always horizontal). The wall points that cause a concave curvature of the structure back face are automatically excluded by the program. The structure is loaded by an active earth pressure.
The procedure for wall verification is described in the theoretical part of the help.
The computed forces are displayed on the desktop and are automatically updated with every change of input data and setting. The right part of the frame shows the result of verification of a wall against overturning and translation. The "In detail" button opens the dialog window, which contains detailed listing of the results of verification analysis.
Visualization of results can be adjusted in the frame "Drawing Settings".
