Abstract： For the features of close models and complex structure, damping of large span space structure has its special properties. In this paper, the basic theories of damping include common damping models and analyzing methods for current practical engineering have been concluded. The research progresses on damping about the overall models consisting of the upper large span frame structure and the supporting concrete structures in recent years are summarized. In the end, the main problems and further research aims on damping of large-span space structure are discussed.
Keywords： space structure, dynamic analysis, damping ratio, time-history analysis
