Numerical and experimental platforms

Experimental means

To carry out its missions, and build programs of experimental research, the SEISM Institute can rely on the experimental platform TAMARIS of the Seismic Mechanics Study Laboratory at CEA Saclay. This installation includes 4 shaking tables, a pit, and a reaction wall. Among these equipments, there is the AZALÉE table, which is currently one of the largest shaking table in the world, outside Japan. Commissioned in 1991, it is used to test large specimens with heavy mass (up to 100 tons). To enforce movements in all directions (3 degrees of freedom, in translation and rotation). The TAMARIS platform also comprises the bi-axial shaking table (horizontal-vertical) TOURNESOL capable of applying mono or bi-axial dynamic loadings to specimens with a mass of up to 10 tons and the mono-axial shaking table VESUVE capable of loading specimens up to 20 tons. Finally, there is the pit IRIS, with a hexagonal section of 4.2 m x 4.2 m and 15 m deep so that mechanical (static or dynamic) loadings can be applied to slender structures such as nuclear reactor control rods. A hydraulic set constituted by 6 electric hydraulic units with a total power of 900 kW can be used to supply the experimental facility at an operating pressure of 210 bar and a maximum possible flow rate of 2200 l/min.

The SEISM Institute also relies on the experimental means of the test center of the LMT, ENS Cachan.

Simulation means

Different theoretical and numerical models developed under different projects involving the Institute are capitalized in several simulation softwares:

  • CAST3M
  • SALOME-MECA
  • EFISPEC3D (BRGM)
  • SPEC3D
  • MKA3D
