Recent Progress of Application of Modern Anti-Seismic Systems in Europe - Part 2: Energy Dissipation Systems, Shape Memory Alloy Devices and Shock Transmitters

Abstract eng:
As mentioned in a separate paper presented at this conference, there are already well over 8,000 structures in the world that are protected by seismic isolation (SI), energy dissipation (ED) and other modern seismic vibration passive control (SVPC) devices, such as shock transmitter units (STUs) and shape memory alloy devices (SMADs). The number of applications is increasing everywhere more and more, not only for SI, but also for the other SVPC systems. The conclusive influence of earthquake experience and availability and features of the design rules used on the extension of application has been confirmed for the latter systems, as well. Although the data concerning ED systems, SMADs and STUs are more uncertain than those related to SI, Italy is most probably fourth at worldwide level (after Japan, the P.R. China, the USA) and again first in the European Union for the number of applications of these systems (also thanks to the numerous bridges and viaducts and some important cultural heritage structures protected by them). Italy is now followed by Taiwan, New Zealand, Canada, Mexico, South Korea and Canada. Important applications, although limited to bridges and viaducts, also began in other European countries, namely in Greece, Portugal and Spain; many of them make use of devices manufactured in Italy. Italian devices have also been installed in several other countries. This paper focuses on the application in Italy and other European countries (including the entire Russian Federation) of ED devices, SMADs and STUs, while a separate paper, presented in Special Session S05-01, deals with that of SI systems.
