GCTS SRC-100

The SRC-100 system is a fully automated testing platform that can simulate the dynamic response of soil and rock formations to seismic loads, providing a realistic representation of in-situ soil behavior. It is equipped with laser sensors to perform high-precision, high-accuracy testing in accordance with the most recent international standards and guidelines. The system features advanced hardware and software components that allow for precise control of the test conditions and real-time data acquisition and analysis. This ensures that the results obtained from the system are accurate and reliable and can be used to make critical design decisions. The GCTS Soil Resonant Column and Dynamic Soil Triaxial Testing System combine the features of both resonant column and torsional shear devices into one elegant system. By utilizing all available options, this system is capable of the full spectrum of modulus measurement, ranging from ultra-low strains to high strains with significant overlap.
