Recent earthquakes in many countries of the world have confirmed the potential for very large seismic events that until now were not forecast. The level of disturbance and destruction of highways and bridges as well as life, suffered during these dominant earthquakes were far greater than structural engineers and their associated design codes had predicted. One important lesson that has been learnt is that it is vital that bridges, which connect major transportation routes, must continue to function after an earthquake. In the quest of this realization, new technologies and design efforts by engineers have resulted in the development of seismic protection systems, which include Shock Transmission Units (STU) together with various seismic isolation and energy mitigation devices. In the only book to provide independent, non-proprietary information on the design and application of STUs, the author offers information on a wide range of different applications, including new and existing highway and railway bridges, as well as non-bridge structures such as nuclear power plants. Illustrated case studies included throughout, Shock Transmission Units in Construction is written by a proven expert in STUs and the only world authority on the subject.
