With the development of infrastructure construction, environmental vibrations have become a major concern that influences the quality of life in modern society. The environmental vibrations are caused mainly due to train/road traffic, construction activities and factory operations, etc. The International Symposium on Environmental Vibration (ISEV) is an open forum for scholars and engineers from all over the world to exchange the latest technical information and research findings on the prediction, control and mitigation of environmental vibrations. The conference has been successfully held for five sessions (Hangzhou, China 2003; Okayama, Japan 2005; Taipei 2007; Beijing, China 2009; Chengdu, China 2011), and Tongji University is honored to be the organizer of the 6th International Symposium on Environmental Vibration (ISEV-2013).
