Calculation of cantilever walls

FIDES-CantileverWall serves the clear calculation of angular cantilever walls with spurs in both sides and any number of consoles. By earth pressure methods according to Culmann and Gudehus concentrated loads consider steep slopes and inclined layer boundaries - actively and passively – can be considered correctly. In this way the program can take into account correctly concentrated loads, line loads and area loads as well as any number of slopes for example for the determination of the Earth Pressure. The results are displayed in a compact form directly within the side view of the wall in order to assure a maximum degree of transparency.  

All necessary calculations and verifications will be performed like: earth pressure, ground bearing capacity, tilting, sole pressure, sliding, settlement, ground failure, and sole canting.  All geotechnical verifications can be per-formed according to a global or a partial safety concept (DIN 1054 (2003), SIA or with freely definable coeffi-cients). The dimensioning can be carried out selectively according to the design codes EC2, DIN 1045, DIN1045-1, SIA-262 or ÖNORM B4700.
