Abstract
For thousands of years human beings have built with earth, producing a rich and diverse heritage of vernacular and monumental architecture, small villages and cities, archaeological and still lived sites. In recent years a large number of dramatic seismic events has focused attention on the historic built heritage in general and, in some regions, the earthen built heritage. Most of earthen architecture is undoubtedly particularly vulnerable to seismic activity, but the most seismic areas of the planet still retain a strong constructive tradition that involves the almost exclusive use of this material. The challenge for the conservation of this heritage is huge and very heterogeneous, being the earth architecture equally distributed on the planet and then linked to local geography, climate, environment, and very different social issues. Among all, the problem of preservation of the earthen built heritage in seismic zone is among the most discussed, being the base material poorly mechanic resistant and therefore not suitable to resist the lateral and torsional solicitations caused by earthquakes. A rich literature on the subject is slowly bringing clarity on the correct use of this material in high seismic risk zones. Norms, regulations, guidelines, published in every continent, provide information about the reinforcement intervention strategies of structures damaged by earthquakes, and suggest solutions for designing new constructions to resist to seismic stresses. The paper aims to give an overlook on traditional strategies and current regulations on the specific issue.File | Size | Format | |
