In order to quickly predict the dynamic characteristics of ancient pagoda structures,especially the basic period/frequency of a large number of ancient masonry pagoda structures,this paper first puts forward the basic form of the basic period/frequency prediction formula of ancient masonry pagoda structures on the basis of the basic formula of structural dynamics.Secondly,the measured basic period/frequency of ancient masonry pa-godas in China was collected,and a semi-theoretical and semi-empirical prediction formula for the basic period of ancient masonry pagodas was obtained by means of data fitting.The measured basic period of the ancient pa-goda structure was compared with the calculation result of the prediction formula.The result showed that the prediction deviation was less than 14％.The prediction formula can accurately predict the basic period of ancient masonry pagoda structure in good structural condition,and meet the requirements of cultural relics pro-tection projects.
