Science, techniques and legal norms

The reconstruction work required from the scientific community, the professionals, the enterprises and the Institutions, the ability to resolve technical problems of great complexity.

degli edifici in muratura, Regione Autonoma Friuli Venezia Giulia, 1977

In fact, earthquakes were still a little studied phenomenon in Italy during the 1970s. Anti-seismic engineering was just taking its first steps. There were no precedents from which to draw inspiration. The restoration of earthquake-damaged buildings raised problems unheard of in the field of engineering. The dynamic behaviour of stone buildings was not known, how to intervene to render them anti-seismic was not understood, which techniques were useful in the repairing of damaged structures were still a mystery. The world of scientific and technological research mobilized itself. Resistance tests were carried out on materials, structural calculation models were prepared in order to guide planning, and construction methods able to give greater solidity to buildings were studied. It was a challenge that was taken up and that quickly brought about a rapid improvement in knowledge and to its equally fast diffusion.

Besides the damage to the buildings, the earthquake also provoked obvious lacerations to the natural environment, sometimes modifying the features of the landscape. Hundreds of landslide episodes opened extended crevices in the mountainous slopes. Deep cracks marked the land. Water and sand mixtures leaked from below ground. The effects of the earthquake started a process of study that was useful for the prevention and the management of similar, new emergency events. The numerous studies on micro-zonation carried out in the most seismically-affected areas represented an authentic turning-point. The areas of greatest geologic, seismic, hydrologic and landslide risk were identified and mapped.

Furthermore, it was clear that the reconstruction process needed transparency, shared rules, certain technical-economic parameters and cost control. In 1977, fundamental laws were approved which established the guidelines to which Friuli would be reconstructed. These were the fundamental laws of the reconstruction: State Law 8th August 1977 n° 546, Regional Law 26th June 1977 n° 30 on the repair of houses that foresaw structural repair and anti-seismic adaptation work, and Regional Law 23rd December 1977 n° 63 on reconstruction. The immediacy, the consistency of the funding and the farsightedness of the contents of these provisions were merit of the Friulan parliamentarians and regional council officers. They overcame the political divisions in order to make themselves the instrument of a strong task force. The state norm simplified the procedures, allocated the funding, and handed the responsibility of the whole reconstruction phase to the Friuli Venezia Giulia Region. The regional legislation put into effect ulterior decentralization of action to the local agencies. It defined the delegated institutional structures to the reconstruction and instituted the technical structures aimed at the verification of the correct application of the norms.
