The sliding check is activated by default in the geotechnical design configuration. You can find the theoretical background of the sliding design in Chapter Theory Basics.
Sliding resistance
If you want to perform the sliding design, you must assign an associated characteristic load combination to each ULS load combination. You can do this in the Load Cases and Combinations tab.
Passive soil pressure
For the design of concrete foundations, the passive earth pressure is preset not to be considered in the sliding analysis. If you want to consider the passive earth pressure, activate the Consider passive earth pressure option in the configuration of the geotechnical analysis.
After activating the passive earth pressure, you can define the characteristic values of the resisting forces at the individual foundation sides.
Resistance limit for undrained clay soil
If the sliding resistance has to be reduced according to 6.5.3(12), you can activate the option Consider resistance limit acc. to 6.5.3(12) for undrained clay soil in the geotechnical design configuration.
