Vibration Response Analysis Of Building Structure Induced By Running Subway

With the rapid development of the Metro Rail Transit in China, people enjoy thespeediness and convenience which the Metro Rail Transit brings to, they also pay moreattention to the effects of vibration induced by the running subway on the neighbouringbuildings. In this thesis, the environment vibration induced by the running subway is studiedby using the measured data which based on the vibration measurement of the third linesubway in Guangzhou and numeric simulation method. The main research contents are asfollows:The characteristics and propagation law of ground vibration induced by the runningsubway is analyzed according to the curve of the vibration acceleration time history. Using theFourier transform,the Fourier acceleration amplitude spectrum can show the composition ofthe vibration frequency and the distribution in each frequency band, thus providing support tothe vibration isolation. The vibration level which calculated by the formula compared with thenational standard, getting the vibration level along the subway.In the structure analysis software ANSYS, the six-story reinforced concrete framestructure can be established.The vibration response of the structure can be calculated by thenumeric simulation, according to consistent input and multi-point input, considering fourdifferent distances between the structures and the subway tunnel centerline. The comparisonof these data can get the characteristics of the vibration response of the surrounding buildings.In the analysis of vibration control for building around the subway, by setting the rubberisolation bearings on foundations of the building, this paper compares the vibration responseof the isolated building with the vibration response of the non-isolated building, andresearches the vibration response under the earthquake.
