INSPIRE: "Innovative Ground Interface Concepts for Structure Protection"


The goal of INSPIRE is to foster a new generation of highly qualified researchers and engineers able to implement novel soil-foundation-structure concepts for the efficient protection of structures from all ground induced hazards, including earthquakes and all other sources of low-frequency noise and vibration excitations.
INSPIRE relies on recent innovative scientific and technological concepts, mainly developed within the broad concept of meta-materials – natural or artificial materials or structures which exhibit extraordinary properties for inhibiting or conditioning wave propagation in all spatial directions over broad frequency bands. General developments of meta-materials will be combined or enriched with novel absorption and isolation concepts (i.e negative effective mass and stiffness moduli media, novel friction vibro-impact rocking motion based non-linear mechanisms) with the goal to overcome the limitations of the existing seismic and low-frequency isolation technologies and deliver highly-damped, low maintenance and easily implemented designs.
This network is led by National Technical University of Athens and consists of 7 European universities (Univ. of Trento, ETH, Univ. of Lille, Technical University of Keiserslauten, Univ. of Mons, Univ of Bologna) 1 Research Institute (Institut Fresnel of the Centre National de la Recherche Scientifique) as well as 5 industrial partners (RINAC, FIP, ADT, IGF, GRSc).

Objectives of ESR04 - Institut Fresnel:
- 1- Design a seismic wave cloaking approach using conformal and non-euclidean elastodynamic tools, able to be implemented in practice with appropriate columns distributed in a soft soil (see figure for preliminary results).
- 2- Verify the results with Time-domain numerical simulations using a finite-difference-time-domain (FDTD) software and frequency-domain simulations with a finite element software to geometries surrounding the buildings, as well as to geometrical constraints of the surrounding soil terrains.

Expected Results of ESR04 :
- 1- A new concept of a cloak/waveguide
- 2- New numerical tools for non-linear transformation elasto-dynamics, taking into account arbitrary soil geometries

Planned secondments :

  • TREVI/geotechnical engineering (3 months)
  • JRC/Seismic protection(2 months)
  • UNITN/modelling of elastic media (1 month)
