Abstract
Damping is an important nature for vibration of structure. Vibration experiments on actual shell structures were carried out to clarify damping characteristics of the shell structures, 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 are the microtremor observation and the impact vibration experiment, and the analytical method for evaluating damping ratios are the RD technique and the half-power method, respectively.
