Analysis of dynamical test for a masonry vajra throne pagoda in Cideng Temple
摘要
Abstract
To study the dynamic characters of the vajre throne pagoda of Cideng Temple in Hohhot,Inner Mongolia Autonomous Region,the vibration response of the pagoda is test excited by ground random on dynamical test equipments.The vibration frequencies and modes of five towers above the vajre are acquired by analysis in time domain and frequency domain.The numerical model is built for the calculation of the dynamical characters of the structures,with the results being consistent with those of the test by adapting to the parameters and the dynamical characters being analyzed.As results,the first two stage vibration frequencies are nearly among the four pagodas at the corner but they are fewer than those of the middle pagoda.The first two stage vibration mode curves are similar and the vibration mode coordination values appear in a different way.When the vajre is considered to be in simulation calculation,the frequencies of each pagoda are reduced while the mode coordination values are increased.Therefore,the distribution of mass and stiffness of each pagoda is consistent along with height,and however the vibration mode coordinate values and damp are influenced by local weaken stiffness because of the differences in structural damage to each pagoda.Nevertheless the vajre throne is effected to the results of dynamical characters of the pagoda.关键词
