F.E.M. CODE FEA SLOPE
FEA – Slope is a very up-to-date slope stability program based on a sophysticated Finite Element geotechnical analysis (F.E.A.), fully developed by Studio Terrain.
The slope is described in eight-noded finite elements, having each peculiar characteristics.
Geotechnical input is in terms of cohesion, angle of internal shear, dilatancy, Poisson's ratio and soil Modulus.
The model encompass a failure function of non-associated type based on Mohr-Coulomb criterion, implementing a visco-plastic algorithm.
The solution allows for presence of groundwater, earthquake forces, external surcharges.
Fea Slope implements a SRF technique for the determination of the safety factor Fs.
Many types of structures can be analyzed in order to state geotechnical stability.
PROGRAM DIAFRAM 5.0 (in Italian)
Diafram is written by geotechnical engineers and devoted to geotechnical engineers' practice.
The program can perform a multi-level approach to the problem of flexible retaining structures:
- pre-dimensioning of a diaphragm
- verification at the SLU of the structure
- verification at the SLE of settlements to be expected.
Different types of structures can be taken in consideration: diaphragm walls excavated and cast under bentonite muds, sheet piles, groups of micro-piles, jet grouted columns, etc., considering a wichever number of tie-back levels.
Groundwater in soil can be modeled in presence of imperious
bottom layers ("static" neutral pressures) or in pre4sence of a filtration flow
("dynamic" conditions in presence of soil dewatering).
Seismic analysis can be performed after Mononobe-Okabe approach, fulfilling tall
requirements from modern building codes.
Calculation algorithms were widespread tested in a very long and comfortable author's practice, with a great number of structures satisfactory designed and realized.
Basic routines were first developed and tested inside the technical office of a leading firm in the field of diaphragm walls (ICOS s.p.a.).
Documentation coming with the program is complete and exhaustive, regularly updated with reference to the most recent building technical regulations.
These manuals are accompaining the software:
- Theoretic Manual
- User's Manual
- Examples of validations
- Examples of calculations
