STX-200 Hydraulic Cyclic Triaxial System


The GCTS STX-200 Hydraulic Cyclic Triaxial System is excellent for measuring liquefaction, resilient modulus, cyclic strength, complex modulus, and other dynamic triaxial tests including synchronized cyclic axial and confining stress loading. Standard and Large Scale systems are available.

 

  • Closed-Loop Digital Servo Control
  • Specimen Diameter up to 100 mm
  • Dynamic and Static Loading
  • Load capacity of 50 kN for static loading and 40 kN for dynamic loading
  • Frequencies up to 30 Hz
  • Electro-hydraulic
  • Biaxial dynamic tests up to 5 Hz with synchronized loading
  • Cell Pressures up to 1,000 kPa
  • Meets ASTM D-3999 & D-5311 Standards
  • Larger cell capacity, axial load capacity, and specimen diameter options available

 

 

The STX-200 triaxial testing system is intended for performing dynamic tests for liquefaction, resilient modulus, cyclic strength, complex modulus, and other dynamic triaxial tests including synchronized cyclic axial and confining stress loading. This system also provides the necessary versatility to automatically perform conventional triaxial tests as well as advanced procedures such as stress or strain path.

 

The standard STX-200 system includes all the necessary hardware and software to automatically perform all triaxial stages including saturation, consolidation, and easily created cyclic and static customized test procedures. It allows creation of an unlimited variety of waveforms including user-generated profiles such as a digitized earthquake record. The system software provides advice for the user as to how to perform testing tasks.

 

The program helps the user select the proper testing parameters and provides the necessary information required to automatically execute the desired test. The Graphical User Interface helps minimize learning time and enables laboratory personnel to conduct more complex, but realistic, testing programs at substantially lower operating cost and also with minimal operator error.

 

Summary results for individual test specimens can be generated in report format and files can be merged to produce a Mohr envelope plot for up to five specimens. Data acquired from all the software modules can be easily transferred to other programs like spreadsheets, databases, etc.

 

Standard systems available for testing specimens with a diameter of 35-mm to 100-mm. Large-Scale systems are also available.

  • 50 kN axial load capacity
  • 1000 kPa confining pressure capacity
  • 30 Hz maximum frequency
  • 100 mm maximum specimen diameter
