AMRetain™

 AMRetain™ design software version 1.2

 

AMRetain™’ is a new design software developed solely for the design of steel sheet piling structures using the ArcelorMittal range of steel sheet piles. AMRetain is quite a versatile design software, based on a ‘Subgrade Reaction Model’ (also called ‘Soil Structure Interaction Model’, or SSIM). This SSIM is an excellent compromise between quite simple design methods like the ‘Limit Equilibrium method’ (LEM) and more complex ones like the ‘Finite ‘Elements Method’ (FEM).

The basic idea was to replace ArcelorMittal’s free software ‘Prosheet’ which is based on a ‘Limit Equilibrium method’, and additionally to add the feature of the design of sheet pile structures based on the new European standards Eurocodes.

The aim of ArcelorMittal is to provide to the industry a valuable, user-friendly, and state-of-the-art software to design cost-effective steel sheet pile retaining walls. AMRetain is available at a reasonable price which covers partially the cost of its distribution, technical support and royalty fees. The intent is not to compete with existing commercial software. The target are civil and geotechnical engineers with a basic knowledge of design of retaining structures, but who do not deal on a regular basis with the design of complex retaining structures, for which a SSIM is definitely more adequate than a LEM approach.

AMRetain allows the design of cantilever walls, as well as single and multi-anchored (or propped) retaining walls. Furthermore, it can also calculate a double sheet-pile wall with one or two anchors / struts level(s). A key feature is the possibility to simulate the different construction phases, which is not possible with standard LEM based software.

 There are two options:

  • design of a retaining wall with a SSIM model. In principle, this is the method that can be used with the ‘Allowable Stress Design’ (ASD) method, which is based on a global safety approach (global safety factor)
  • design based on the French standard NF P 94‑282, which is the French National Annex of Eurocode 7, Part 1. It is based on ‘Design Approach 2’ from EN 1997-1, and uses the partial safety factors and some additional assumptions from the French standard. In this mode, the length of active anchors can also be determined.

Please note that the chosen design method based on Eurocode 7 is not valid for all the European countries, as every country may chose between three different ‘design approaches’ (see EN 1997-1 for more details). Besides, in their NAD, every country is free to adapt proposed values for some parameters (‘Nationally Determined Parameters’) of the Eurocode, like the partial safety factors.

Besides, the user can either work in ‘metric units (SI system) or in ‘imperial units (usual units in the United States).

AMRetain works in a Microsoft Windowsâ operating system (XP and following versions). It is based on ‘KRea’, a commercial software developed by the French company ‘Terrasol’ (www.terrasol.fr). Some features were added to the basic version of KRea on top of the new European design method.
