The Research Unit of SDGEE has long and internationally recognized experience in all kind of laboratory testing under static and dynamic conditions. It is equipped with state-of-the-art laboratory apparatuses to perform both routine determination of physical, mechanical and dynamic soil properties, as well as high- quality research in soils, soil mixtures with recycled material (rubbers, pumice etc) and rock. We provide the following services:
-
Soil classification and evaluation of physical properties
-
Testing of soil samples (intact and remolded) of different dimensions under various strain/stress conditions for all kind of geotechnical projects
-
Evaluation of dynamic soil properties (stiffness and damping) at a wide range of strains
-
Evaluation of liquefaction potential
-
Small-scale shaking table testing (new)
The Research Unit of SDGEE has recently installed and operates a small (max 100kg) shaking table (ANCO R-201) for earthquake engineering, vibration, system dynamics, control systems, and data acquisition and processing studies and demonstrations:
-
1.5g acceleration with 80kg payload
-
Peak displacement of +/- 12 cm
-
Peak velocity of 50 cm/s
-
Frequency range of operation 0 to greater than 20 Hz
