Verification
The frame "Verification" shows the analysis results.
To perform verification of external stability the program creates a fictitious structure (wall) which is then checked for overturning and slip. The fictitious wall consists of the structure front face and a curve bounding the end points of geo-reinforcements. The fictitious structure is loaded by an active earth pressure. The actual verification procedure is described in the theoretical part of the help.
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 case the last column is not displayed.
Several computations can be carried out for a single task. 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 slip. 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".
