Units Conversion Tool

EngiLab Units is an easy-to-use yet powerful unit conversion tool for Windows.

Structural Analysis and Design of Timber Structures

Timber Tech Buildings is a structural design software for analysis of timber shear walls structures realized using both CLT and platform frame systems born at University of Trento and developed by TimberTech.

Finite Element Analysis Package for 2D and 3D Constructions

Analysis3D calculates two- and three-dimensional Trusses and Frames. These structures consist of long slender Members that are supposed to behave linear elastic.

Sieve Analysis, Hydrometer and Atterberg Limits Tests

SO-Sieve having a user-friendly interface, includes sieve analysis, hydrometer and Atterberg limits tests.

Raster to Vector Converter

WinTopo is a high quality software application for converting TIF, JPG, PNG, GIF, BMP files and scanned images into useful vector files suitable for CAD, GIS and CNC applications.

Site and Road Engineering 3D Design

Site3D is a fully featured software product for the engineering design of road systems and housing developments.

Pavement Analysis Tool

ELLEA1 performs real time computation of stresses, strains and displacements in a layered elastic half-space due to two uniformly loaded circular areas applied at the surface

Design Of Wooden Structures

The program for the sizing of wooden structures, for fire tests, for the calculation of metal connections, of the structural joins and of the wood-concrete collaborating floors.

Two-Dimensional Geotechnical Finite Element Program

ADONIS is an easy-to-use yet powerful geotechnical-engineering tool for the linear and nonlinear analysis of geotechnical problems.

Geotechnical Engineering Boring Logs

SO-Log generates boring logs as a means to summarize and report several tests performed within a geotechnical engineering project.

Pile Capacity Analysis

RSPile is a program for the calculation of the axial load capacity of driven piles and the analysis of piles under lateral loading.

3D Finite Element Analysis for Rock and Soil

RS3 is a 3D finite element analysis program that can be used for a wide range of applications in both rock and soil, such as underground excavations, sequenced tunneling, surface excavations, slope stability, seepage analysis, consolidation analysis, and much more.
