Finite Element calculation of excavation pit walls
Because of the increasing building density in cities, a higher
demand for analysis of deformations of retainment walls is
necessary. The program WALLS-FEM with its effective input and
its automatic mesh generation provides an economic way to get a
calculation of complex excavation pit walls. The
SOFiSTiK-calculation kernel implemented in WALLS-FEM computes
realistic settlement dells and wall deformations using modern
ways of material definitions in all construction stages
according to the new recommendation EB103 of the EAB.
WALLS-FEM presents itself as the ideal complement for the
WALLS-series (the classic walls excavation calculation
program). In this combination with the program WALLS-Retain
first you will design the geometry, compute the
walls anchoring depth and anchor length due to the formulas of
the EAB, then you can import the complete system into WALLS-FEM
and after few additional steps you can perform the FE-analysis.
With the FEA all relative displacements of soil anchors and
wall will fully be considered and now you can verify wether the
assumption of the EAB for this case were valid or not. Because
of the interactive design of all objects (like anchor angle
and -length, initial tension...) the system can be optimised
very easily, e.g. for the minimisation of the settlements.
