At the end of the number of the Chinese isolated buildings had increased to more than and included even rather tall constructions. Moreover: SI had already been applied to 5 further large span structures and 20 road and railway bridges or viaducts; 30 buildings were already protected by ED devices; 5 buildings and 6 bridges were already been provided with hybrid or semi-active seismic vibration control systems. SI had also already been used, for the first time in the P.

In the P. China passed the Russian Federation Martelli and Forni : in fact, the Chinese isolated buildings were in May against the approximately declared at that time by the Russian experts — see Martelli and Forni and those protected by ED systems The first included the so-called Isolation House Building on Subway Hub, completed near the centre of Beijing in , which consists of 20 7- to 9-storey buildings, all separately isolated above an unique huge 2-storey isolated structure that contains all services and infrastructures, including railways and subways Dolce et al.

In October , the number of isolated Chinese buildings was about In November a further significant extension of the applications of the AS systems was reported in the P. This more rapid increase of the number of building applications of SI was due to both the excellent behaviour of two r. In November SI systems had been installed in the P.

The latter had also been installed in 8 bridges. SI has been applied in the P.

China not only at the building base or at the top of the lowest floor, but also on more elevated floors for risings or for erecting highly vertically asymmetric constructions , or at the building top to sustain, in the case of retrofit, one or more new floors acting as a TMD , or also on structures that join adjacent buildings having different vibrational behaviours.

More recent applications also included sets of buildings on artificial ground, base and roof SI of stadiums and the protection of valuable objects e. More recently, the number of applications of the AS systems really strongly increased in the P. In fact, it was reported by Eisenberg et al. China to protect 4, buildings, bridges and viaducts and even 50 industrial structures e.

The Lushan event caused deaths besides 21 missing people and the wounding of , people. About 40, buildings i.

The heavily damaged buildings included numerous strategic and public buildings including schools and hospitals , even constructed or reconstructed after the Wenchuan event. However, where it was used, SI showed, once again, an excellent effectiveness. Particularly interesting were, in Lushan, two cases of r.

About the two schools, while for that conventionally founded the PGA value of 0. Thus, the effectiveness of SI can be quantified in a reduction factor of the roof maximum acceleration equal to 6.

As to the county hospital Fig. After the retrofits of some important historical buildings Dolce et al. China, for the overall number of applications of the AS systems and devices Eisenberg et al. In this country, however, such applications go on being satisfactorily progressing only for bridges and viaducts and for buildings protected by ED systems.

They concern both new constructions and retrofits. On the contrary, as far as SI of buildings is concerned, the number of new applications remains still limited recently 3 or 4 per year , in spite of the excellent behaviour of some important U. This is a consequence of the very penalizing design code in force in the USA for the isolated buildings: these were not more than in September and are now approximately , although the related applications are mostly very important and half of them are retrofits, even of monumental buildings Martelli and Forni With regards to the design earthquake levels adopted in California, Martelli and Forni stressed that they correspond very large magnitudes e.

There, the use of the AS systems began in for bridges and viaducts and in for buildings Dolce et al. In spite of the aforesaid pioneering role of Italy in the development and application of the passive AS systems, in the years s their use remained rather limited several years long, due to the lack of design rules to the end of , then due to their inadequacy and a very complicated and time-consuming approval process to Dolce et al.

FPS devices in the years — and one of the isolators during and after its installation. To the knowledge of the authors, this is the only application of SI to chemical plants and components so far existing in Italy prior to the Abruzzo earthquake, it was also the only application of CSS devices in Italy Open image in new window Fig.

Martelli in The use of SI became particularly rapid especially after the Abruzzo earthquake of April 6, , as a consequence of the large damage caused by this event to the conventionally founded structures and cultural heritage Martelli and Forni , b. The recent applications of SI include wood, r.

These were seismically isolated, for the first time in Italy, using CSS devices manufactured in the country Fig. In particular, the new Francesco Jovine school Fig. Right: detail of one of the 40 CSS devices, manufactured in Italy, which have been installed at the top of columns made of steel or r.

Since the occurrence of induced earthquakes is directly related to human activities, the attraction of this approach—which is not available when confronting the threat of natural tectonic earthquakes—is obvious, since control of the causative activity could be expected to result in control of consequent seismicity.
