The dynamic behavior is an important index to evaluate the seismic property and structure damage of historic pagodae.On the base of the research of protection technology on Jinaozhou pagoda, the key points and schemes for applied ambient random excitation technology to determine the dynamic behavior of ancient masonry pagodas is introduced.The test scheme for Jinaozhou pagoda is verified by the results of finite element software Strand7. The similarities and the differences between them are discussed and the causes are analyzed.It is believed that the present research can provide a valuable reference for the eternal protection, reasonable development and utility & test of similar ancient pagodas.
