Controlling seismic elastic surface waves via interacting structures

We present some recent research advances on controlling elastic surface waves in thin and thick plates, this is aimed at understanding the seismic wave trajectories in soils structured with buildings. We show the influence of building interactions on surface and body waves when a significant proportion of soil is replaced by inclusions with different densities and Lamécoefficients acting as building foundation, raising the question of the effective dynamic properties of these smart soils. One of our objectives is to improve the control of seismic waves by taking into consideration the in-plane twisting motion of local helical resonators.
