A damping vibration experiment was carried out on an actual shell structure (a PC cylindrical shell) to clarify damping characteristics of the shell structure, and also to aid in preparing a data base on damping ratios of shell and spatial structures for use in dynamic response analysis. The experimental methods used were microtremor observation and a human excitation experiment. The analytical methods used for evaluating damping ratios were the random decrement technique (RD technique) and the half-power method.
