Sheet walls are relatively thin, vertical structures, embedded in terrain to a depth sufficient to support an uphill embankment/downhill excavation thrust, including water and surcharges. This type of structure can be constructed of driven prefabricated steel pile sections, adjacent, bored cylindrical piles, and reinforced concrete sheet elements usually produced on site. The methods used for analysis / verification are: Limit Equilibrium Method (LEM) and Finite Elements Method (FEM). The methods mentioned are of increasing complexity from both the numerical point of view and for the amount of geotechnical parameters necessary for the calculation.

Easy MASW is a new software for the interpretation and archiving of seismic data using the MASW method (Multi-Channel Analysis of Surface Waves). It is a very easy-to-use application that, with simple steps, performs the analysis of the shear waves velocities Vs. The software allows the inversion using more modes. During the spectral processing phase the user can view the dispersion of a customizable synthetic model and the results are plotted directly on the velocity-frequency spectrum. The generation of the velocity-frequency spectrum has been improved to allow a more effective identification of modes. The user can select the points on which the inversion is performed directly on the velocity-frequency spectrum and assign to each point the mode to which it refers.

Features:

Hydrologic Risk allows the determination of the Hydrologic and Hydraulic risk in a basin or courses confluent to a main river trunk. The characteristics of the discrete elements (basin, course etc.) in terms of affluence and effluence quantitively and temporally can be determined and thereby the flood flow rate of segments under consideration is derived.

Trelis is csimsoft's high-end commercial pre-processor for FEA and CFD, based on the time-proven Cubit software from Sandia National Laboratories. For more than two decades, csimsoft has developed Cubit in conjunction with Sandia, and is Sandia's authorized distributor for academic and commercial use.

CVSoil is a complete and innovative tool for the determination of characteristic geotechnical parameters according to a probabilistic approach, considering the statistical quantities obtained from a suitable sample of tests. With the introduction of the concept of limit state was developed in parallel also the concept of characteristic value. Eurocode 7 concerning the geotechnical design, introduces for the first time the characteristic values of geotechnical parameters. The characteristic value, understood as a precautionary estimate of the parameter which influences the onset of the limit state into consideration, must be used in any type of geotechnical verification. The works must be verified for the ultimate limit states that may occur as a consequence of different combinations of actions and for the serviceability limit state, defined in relation to the expected benefits.

GeoRock 3D is a program for three dimensional analysis of rock fall and for the design and optimisation of protective works utilising a sophisticated algorithm for spatial analysis.

Slope modelling:

GeoRock 2D is a software for the 2D simulation of rockfalls using Lumped Mass and C.R.S.P. models.

For the Lumped Mass model, the computation assumptions are: plan outline, the slope profile similar to a broken line consisting of straight line segments; point boulder and neglectable air resistance.

CRSP (Colorado Rockfall Simulation Program) model has been developed by Pfeiffer and Bowen (1989) with the purpose of modeling the falling motion of boulders having the shape of spheres, cylinders or discs, with circular cross section in the vertical plane of the movement. The reliability of the model was verified by comparisons between numerical results and the results obtained from in situ tests.

The software is interfaced with other GeoStru programs: TriSpace for the automatic generation of sections from an xyz plane or from raster images; GeoStru SRTM for the automatic generation of topographical sections starting from Google Maps; GeoStru Maps, the new online App from GeoStru, that allows you to create topographic sections in a very simple way.
