VIBRATION AND SEISMIC ACTION ABATEMENT METHOD FOR STRUCTURES

Abstract

The new estimation method of the seismic isolation of the whole nuclear power plant building and the vibration isolation method of structures will be introduced. This method has been developed by Professor E. Kurbatskiy. The method is based on the properties of Fourier transforms finite functions and gives opportunities to estimate effectiveness of different means of seismic protection. At present time the new production power-generating units of nuclear plant are under consideration in Russian Federation. One of the tasks of this problem is to create the structures that can be used in the high seismic activity regions. In many industrial areas there appears a significant problem of isolation from vibration caused by trains and different equipment. An inexpensive way of vibroisolation by placing granular rubber or polymer -soil mixtures around foundations can be of great benefit to the infrastructure protection. In recent years, the disposal of scrap tires has become a significant environmental problem. Utilizing rubber tires in earthquake hazard mitigation can be a viable approach of resolving the chronic problems associated with waste tire disposal and costly provisions for the earthquake and vibration protection of the infrastructure. Applications of artificial granular medium to vibration and seismic isolation are offered.
