LISG - Laboratory of Structural and Geotechnical Engineering
The Laboratory of Structural and Geotechnical Engineering LISG is divided into the Materials Resistance section (LISG - RM), the Structural Testing section (LISG - PS) and the Soil Testing section (LISG - GEO).

Research areas
The scientific field in which the activity of the three sectors takes place can be split into different disciplines:
- LISG – RM (Materials Resistance, ex-LARM): Construction Science discipline
- LISG – PS (Structure Test, ex-LAPS): discipline of Construction Technique
- LISG – GEO (Soil Testing): Soil Mechanics and Geotechnical Engineering
The research field of LISG involves a wide range of aspects of experimental control, both of new buildings and of those with historical and monumental nature. These include the determination of the mechanical properties of materials, quality control, the study of the mechanical behaviour of models and structural elements, both in the static and dynamic field, non-destructive testing and monitoring of structures.
LISG activities also relate to the analysis of the mechanical behaviour of soils, through standard and advanced laboratory tests. Research themes connected to the laboratory encompass the site characterization and the related numerical modelling, with applications in the context of hydrogeological risk mitigation and cultural heritage preservation.
In particular:
- LISG – RM offers support to experimental activities related to research on the Mechanics of Solids and Structures (further details on research activities of section “Materials Resistance”)
- LISG – PS carries out support and development activities for scientific and research studies in the field of structural engineering
- LISG – GEO offers support to scientific and research activities in the field of Soil Mechanics and Geotechnical Engineering (further details on research activities of section ‘’Soil Testing”)
Services and consultancy
LISG carries out experimental activities in the laboratory and in the field at the service of companies, organizations and individuals. In particular:
- consultancy agreements, tests on building materials, structural elements and structures in regulated contexts and in innovative contexts not yet regulated are held at LISG - RM
- static load tests, tests for the evaluation of the mechanical behavior of prefabricated building systems, dynamic tests in situ and long-term tests in controlled climatic conditions are carried out at LISG – PS
- At LISG - GEO standard and advanced laboratory tests can be carried out on soil samples (further details on services and scientific expertise in the section “Soil Testing”)
Educational activities and training
LISG offers support to:
- Bachelor and master theses
- Research projects of PhD students, exchange PhD students from foreign universities, post-doc research activity
- Orientation days for high school students
LISG-RM offers support to:
