Information obtained from Wallap analysesįailure of structural members by excessive deformation, formation of a mechanism or rupture Each is denoted by an acronym: B+H p.32 §2.7 EC7 identifies several different ULSs which must be verified. Is concerned with collapse or instability of the works which may affect the safety of people or the structure, or cause major economic loss. Is concerned with functioning of the structure (and adjacent structures), the comfort of people and the appearance of the works. (1996) Geotechnical Earthquake Engineering.

Excellent presentation (and resolution) of conflicting interpretations of EC7. With this, C580 and the Designers' Guide (above) you may never need to read EN 1997-1.

Partial factor on strength of strut / anchor Partial factor on strut / anchor strength Partial factor on bending strength of wall Partial factor on undrained shear strength Notation aULS, aSLS ULS and SLS seismic accelerationsĬharacteristic value of a material propertyĬharacteristic angle of shearing resistance This note endeavours to set out and justify some of the choices which must be made during the design process so that the WALLAP user can a) arrive at a rational design. The note does not describe the operational aspects of WALLAP which are set out in the WALLAP Help system The requirements of EC7 are not always easy to understand or implement and in practice one encounters a variety of interpretations. The purpose of this note is to summarise the requirements of EC7 as they relate to embedded retaining walls 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 stages of construction. WALLAP carries out Limit Equilibrium and Soil-Structure Interaction analyses at each stage of the construction sequence. There are also options for user-defined Limit States for those who wish to design according to codes other than EC7. Separate data sets (SLS and ULS parameters) can be generated in order to fully investigate the various Limit States.

The use of WALLAP in the context of Eurocode 7 (EN 1997-1, Eurocode 7:Geotechnical Design) WALLAP version 6 (June 2012) introduces a new feature to simplify the preparation of data in accordance with the different Limit State analyses required by EC7.
