GGU-CANTILEVER: Design
When you begin an analysis, the program requires the stiffnesses of the cantilever wall and any anchors and struts present. The stiffness EI of the wall is acquired from E·d³/12, where d is the thickness of the wall in the section under consideration. The stiffness of each element is assumed as constant, where the thickness is the thickness at the centre of the section. The remaining values of any anchors or struts can be specified before beginning the analysis.
The program first computes the internal forces of the cantilever wall above the footing (see
figures in “Theoretical principles: Determination of wall loads for reinforced concrete design” - Base of wall (stem) Example 1/Example 2). The wall is then designed using the identified internal forces.
The earth and water pressures are then calculated for the entire system with footings. Together with the self weights and area loads, bounded or double-bounded surcharges, stability analysis can now be performed:
calculation of bearing capacity safety to DIN 4017
calculation of sliding safety
calculation of overturning safety
calculation of settlements to DIN 4019
calculation of hydraulic heave safety
calculation of buoyancy safety
calculation of heave of anchor soil
By going to the menu items "Editor 1/Verifications/Partial factors" and "Editor 1/Buoyancy + Hydraulic heave", you can select the verification to be performed.
The settlement analysis can be activated or deactivated by going to "Editor 2/Settlements".
