Densely built structures are analytically investigated focusing on their seismic response and their effects on the wave propagating characteristics in an irregularly layered soil for vertically incident SV wave. Seismic responses of densely built structures are reduced in comparison with those of single structures for both layered and irregularly layered soil mainly due to inertial effect of structures. For horizontally travelling waves like surface waves, effects of plural structures are smaller on the front-end structure than those in the rear side. Densely built structures affect wave propagating characteristics in the neighboring soil by inducing Rayleigh wave due to their inertial effects. In the irregularly layered soil, effects of structures on wave propagation are varied according to the location of the structures.
