Efficient Bridge Seismic Isolation System with Innovative Multi-Level Seismic Energy Balance

Abstract eng:
Development of advanced technology applicable for efficient prevention of heavy earthquake damage and total collapse of existing and new bridges in future earthquakes was challenging motivation of the second author to start with realization of long-term pilot-innovative project entitled: “High Performance Seismic Isolation of Bridges”. The developed new technology for qualitatively improved seismic protection of bridge structures is based on application of the patented “GOSEB3” system for construction of seismically safe structures. Qualitative step of GOSEB3 (generation-3) innovative seismically-resistant bridge system, is created with full multi-level global optimization of seismic energy balance. The innovative project was officially nominated by the Government of the Republic of Macedonia to represent new and advanced national achievements in the field of INVENTIONS AND SCIENCE. The research activities have been continued in the frame of 3-year bilateral scientific project Macedonia-Serbia (2005-2007). The new “GOSEB3” high performance seismic isolation system for bridges, actually represent very important technical innovation capable of integrating the advantages of seismic isolation, seismic energy dissipation and effective displacement control. Furthermore, the new seismic isolation system for bridges based on multi-level seismic energy absorption and optimized seismic energy balance shows very high seismic control performances and can be used for full seismic protection of new and seismic revitalization of existing bridges in longitudinal and in transversal direction under the effect of very strong earthquakes. The present research activities are continued to provide conditions for wide practical application of the invented GOSEB3 seismic isolation system..
