STX-300 Hydraulic Cyclic Triaxial System


The STX-300 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 from 70 mm to 150 mm.
  • Dynamic and Static Loading.
  • Frequencies up to 30 Hz.
  • Electro-hydraulic.
  • Axial loads up to 100 kN.
  • Cell Pressures up to 2,000 kPa.
  • Meets ASTM D-3999 & D-5311 Standards.

 

 

The STX-300 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-300 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 71-mm, 100-mm, and 150-mm. Large-Scale systems are also available.

  • 100 kN axial load capacity
  • 2000 kPa confining pressure capacity
  • 30 Hz maximum frequency
  • 150 mm maximum specimen diameter
