Abstract:Large scale static and dynamic concrete hydraulic servo triaxial testing system is designed by using computer and hydraulic servo technique. This equipment can be used to conduct static and dynamic combined test. Hydraulic mechanism, concrete element floating device and working principle of feedback controlling device for loading, displacements and strain are introduced in details. Traits of computer code are presented. Application of this equipment in experiment of "Failure Criterion of Concrete under Multiaxial Variable Amplitude Fatigue" shows it is reliable and steady, and can get expectant goals.
Keywords:concrete  triaxial  hydraulic servo  static and dynamic  testing equipment
