The structure vibration induced by building base dynamic excitation often has harmful effect to the comfort of residents or the applicability of precise instrument inside. So, predicting the proposed building vibration is necessary. This paper presents a new method based on multi-source fuzzy finite element dynamic analysis to predict the building vibration caused by traffic loads of vehicles. The uncertain parameters of the dynamic function are the fuzzy sources including structural mass, stiffness, damping matrix and the excitation magnitude on the structure base. The fuzzy dynamic characteristics and frequency response function with multi-source fuzzy number are discussed. Finally, the example with fuzzy excitation on structure base is given. Some key steps of this method are contained: 1) the acquisition of the vibration acceleration data of the ground excitation, 2) the analysis of the one-third octave band power spectrum density of the test data, 3) the construction the fuzzy source membership functions of favorite center frequencies of the one-third octave band, 4) the construction of fuzzy finite element dynamic model of the building which residents complaining. 5) the analysis of the fuzzy membership function of finite element dynamic model response, 6) the overall weighted root-mean-square acceleration value in α-sublevel of fuzzy number by ISO2631-1,2 standard.
