AB  - Metre size inertial resonators located in the ground have been theoreticallyshown to interact with a seismic wave (attenuation, band gaps) to enableprotection of surface structures such as buildings. The challenge for CivilEngineering is to both reduce the size of these resonators and to increasetheir efficiency. Here we explore steel spheres, connected to a concrete bulkmedium, either by a coating of rubber, or rubber and steel ligaments, or airand steel ligaments. We show that for a cubic lattice periodicity of 1 metre,we achieve stop bands in the frequency range 14 to 20 Hz; by splitting spheresin 2 and 8 pieces, we tune down the stop bands frequencies and further increasetheir bandwidth. We thus demonstrate we are able to provide a variety ofinertial resonators with stop bands below 10 Hz i.e., in the frequency range ofinterest for earthquake engineering.
