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 standard selected, amongst which global stability even in seismic conditions. Structural evaluations performs reinforcements sizing and verification with
Ultimate Limit State
or
Allowable Tensions.
Supported computation standards:
Eurocod 7/8
NTC 2008
STAS
British Codes BS8004/BS8110
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.
Optional module G.S.A. "Global Stability Analysis" carries out the
global stability analysis of the wall/soil system using several computation
methods: Fellenius (1936), Bishop (1955), Janbu (1956), Morgenstern &
Price (1965), Spencer (1967), Bell (1968), Sarma (1973), D.E.M. (1992), Zeng
Liang (1995).
Thanks to the manifold options available, the program permits treatment of Reinforced Concrete and Gravity walls in an ample range of cases.

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.
