In order to explore the vibration characteristics of multi storied buildings along the urban rail transit, a 4 story building beside the urban rail transit viaduct of a city is taken as the research object, and vibration tests are performed on each floor simultaneously.Then the vibration characteristics of each floor are analyzed by using linear weighting and Z weighting method, and the two weighting modes are analyzed respectively for the transmission characteristics of vibration under characteristic frequency. Finally, the finite element analysis software ABAQUS is used to establish the model and modal analysis is carried out and the cause of building vibration peak appearing on the 4th floor is found out.The results show that under the linear weighting and Z weighting, the global peak values of the 4 floors all appear in the 50~63Hz frequency range; during the propagation of vibration from the 1st floor to the 4th floor, the vibration acceleration levels of the center frequency of 50Hz and 63Hz frequency decreases at first and then increases and it reaches the minimum at the 2nd floor and reaches the maximum at the 4 floor.Modal analysis shows that when the train passes and when the frequency is 63Hz, the 4th floor resonance occurs, so the vibration is the most obvious.
