Prediction of Metro Train-Induced Vibrations on a Historic Building: The Case of the Round City and Chengguang Hall in Beijing

Abstract

With the development of urban mass transit, the train-induced vibrations become a potential problem to historic buildings nearby. The protection and maintenance of historic buildings have aroused a great deal of public attentions. In this paper, the problem of environmental vibrations was analysed for the Round City and Chengguang Hall, a group of historic buildings in Beijing. The historic buildings are located close to a busy road and are near to a planning subway line. The natural frequencies and dynamic amplification factor of the timber structure were estimated by an empirical method. Then, a finite element model was built to predict the metro train-induced vibrations. The results show that, even if the floating slab track was used train-induced vibration can still be a potential problem against long-term protection for the timber structure.
