GGU-STABILITY: "Footing" menu item

If you activated the "Bearing capacity" option button in the "Editor 1/Analysis options" menu item, a further menu item, "Footing", becomes visible.

Here, you enter the footing parameters required for bearing capacity analysis.

• "x", "y" = position of left footing edge

• "Width" = footing width

• "Inclination" = inclination of footing base

• "V" = vertical load on footing

• "H" = horizontal load on footing

For a bearing capacity analysis the safety is then acquired from a comparison of the failure load V_b and the working strip footing load V_work. (also see Section 9.5):

= V_b/V_work.

For an analysis of bearing capacity the program varies the load V_b until the slope stability FOS   = 1.0 using the global safety factors or the utilisation factor µ = 1.0 using the partial factors. When using variation, the horizontal load is increased or decreased corresponding to the vertical load.
