Many research works about the wave propagation behaviors of continuum spatial structures such as plates and cylindrical shells have been presented. However, due to the numerical difficulty, there are very few research works on for discrete spatial structures. The objective of our research is to examine the wave propagation properties of lattice structures such as single layer lattice domes. We plan to carry out impact hammer experiments on some lattice plates and shells made of acrylic resin for investigating their dynamic properties. In this paper, impact response experiments performed on some cantilever beams with different fixed end stiffness which have been carried out as preliminary experiments for the purpose of evaluating the boundary conditions of lattice plate models and lattice shell models are reported. In the first part, the experimental method and the specimen are explained. In the second part, the experimental results are shown and some comments are explained. In the third part, theoretical results obtained by using simple wave propagation theory are shown and compared with the experimental results.
