If the issue of seismic performance is analysed on the basis of the three fundamental parameters: mass, own period and ductility, it is easy to observe the substantial absence of the former at least as far as the metallic structural elements are concerned.<\/p>\n

The metal structures belong to construction systems that usually include vertical closures and roofs made of lightweight prefabricated sheet metal panels with internal insulation layers, so the consideration of lightness extends to the construction as a whole.<\/p>\n

As far as design choices are concerned, it is easy to be faced with inverted priorities compared to multi-storey buildings.<\/p>\n

The masses are so small that the seismic action becomes secondary to the horizontal action due to the wind, proportional to the width of the surfaces. The project is often developed without resorting to seismic action reduction factors, and the advantages of adopting a steel construction for these structural types are emphasized in seismic zones.<\/p>\n

In the wake of the disastrous seismic events in Umbria\/Marche (1997) and Molise (2002), institutions and public opinion have given particular attention to the problem of earthquake protection.<\/p>\n

The Government Authorities responsible for this purpose have consequently encouraged the development and publication of new regulatory codes:<\/p>\n
