This paper presents a study of the harmful effects of ground borne vibration induced by high speed trains. A model has been designed using ANSYS software to evaluate and predict nearby building damage. A comparison has been conducted between predicted and real peak particle velocity inside the building. To excite the structure model, sample inputs for peak particle velocity are chosen from recommendations by ISO14837-1 standard. Frequency analysis of the output data of the software and comparing such output with ISO14837-1 standard predicts some harmful effects. In order to reduce harmful effects, mechanical dampers were added to the structure model.
