The requirements of EC7 are not always easy to understand or implement and in practice one encountersa variety of interpretations. The note does not describe the operational aspects ofWALLAP which are set out in the WALLAP Help system The purpose of this note is to summarise the requirements of EC7 as they relate to embedded retainingwalls and the use of WALLAP in their design.
Seismic and Accidental situations after the end of construction can also be investigated. This allows the user to investigate both stability and structural forces at all stagesof construction. WALLAP carries out Limit Equilibrium and Soil-Structure Interaction analyses at each stage of theconstruction sequence. There are also optionsfor user-defined Limit States for those who wish to design according to codes other than EC7.
Separate data sets (SLS and ULSparameters) can be generated in order to fully investigate the various Limit States.
WALLAP version 6 (June 2012) introduces a new feature to simplify the preparation of data inaccordance with the different Limit State analyses required by EC7. The use of WALLAP in the context of Eurocode 7(EN 1997-1, Eurocode 7:Geotechnical Design)
