GeoStru - MDC Concrete Retaining Walls Software
MDC is a software product for the design and analysis of reinforced concrete retaining walls either resting on their own foundation or on piles, optionally supported by tiebacks. The geotechnical computation employs the standard geotechnical methods subject to user choice and carries out the verifications prescribed by the selected standard, amongst which global stability even in seismic conditions. Structural evaluations performs reinforcements sizing and verification with Ultimate Limit State or Allowable Tensions. MDC is simple and intuitive but with amazing features including: pre-design work, easy management of the combinations: GEO, STR, GLOBAL STABILITY , localization and automatic import of seismic parameters, displacements analysis in dynamic field, reinforcements editor, Import and export of works that should fall in stabilization operations.
Software for the design and analysis of reinforced concrete retaining walls either resting on their own foundation or on piles, optionally supported by tiebacks. Thanks to the manifold options available, the program permits treatment of Reinforced Concrete and Gravity walls in an ample range of cases:
Reinforced concrete walls;
Gravity walls;
Walls supported on piles or minipiles;
Walls with tiebacks/anchors;
Walls with a shelf on the uphill side;
Footing keys;
Stepped wall on uphill side;
Tapered profile (stem and footing) on both sides;
Forces acting on wall: FX, FY, MZ on n points;
Layered terrain;
Backfill;
Loads on backfill;
Inclined terrain on uphill and downhill sides;
Ground water or confined water layers;
Drainage insertion on uphill side;
Fixed head walls;
Stress diagrams;
Global stability analysis using several methods: Fellenius, Bishop, Janbu, Bell, Sarma, Morgenstern & Price, D.E.M., Zeng Liang.
Supported computation standards:
Eurocod 7/8

SR EN 1997-1 Anexa RO / EC2: SR EN 1992-1-1 / Normativul pentru proiectarea lucrarilor de sustinere (Anexa A)
The unique feature of this software is the simplicity with which you can manage various combinations of loads summarizing in a single phase both load conditions and computation.
Stratigraphy
Simple layer declaration allow any series of layers to be modelled on uphill and downhill sides of the wall with individual inclination. Mouse click and drag allow layer boundaries to be moved or inclined. To each layer are assigned the geotechnic parameters required for computation and to each may be associated a colour and/or texture. An internal soils database, expandable and amendable by the user, simplifies these choices.
Computation
The user can choose one of the following methods for the computation of thrust: Coulomb, Rankine or Mononobe & Okabe. It is also possible to perform the computation considering the thrust at rest and, for the elemets subject to passive thrust, to impose the percentage of mobilized thrust. The structural computatin and analysis can be performed, at user’s choice, with the Limit States or Allowable Tensions methods.
