Fuzhou University - China

aaaaaaaaaThe three bi-axial shaking table array system for earthquake simulation at Fuzhou University, Civil Engineering Department.

The three table system will provide a powerful research tool
to establish the seismic performance of complex structures
such as:

  • Power distribution, pipelines and electrical distribution
  • Rail and road bridge
  • High rise building models
  • Underground rail system
  • Vibration testing scaled structural models
