The objective of our research is to examine the wave propagation properties of spatial structures. Spatial structures such as shells, space frames, membrane structures, tend to become larger and higher recently. On the case of those structures it may be possible that the structure is locally damaged before it becomes vibration state by an external force. On the other hand, it was reported that the roof of a spatial structure might be affected by a kind of impulsive forces through a hanging object on the ceiling when the Hyogo-ken Nanbu Earthquake occurred. It is seemed that for such spatial structures then the investigation and estimation of dynamic structural behavior from the view point of wave propagation become important. For these purposes, we planned and carried out impact hammer experiments on some lattice-type plates. In this paper the experiment results performed on three lattice-type plates and one continuum plate are shown. The results show that wave propagation properties of lattice-type plates depend on wave propagation properties of the members consist of those lattice-type plates.
