Refuerzo de fustes de columna en la arquitectura monumental de <em>Italica</em> (prov. <em>Baetica</em>). Aplicación de nuevas tecnologías para la reconstrucción de una práctica singular

The pieces under study presented in this paper come from the already well known “Traianeum” of Italica (prov. Baetica, present Santiponce, Seville), a huge complex area, formed by a wide open square with a main central temple, built according to the extension of the city with a new quarter in Hadrian times. Most of them, fragments of column shafts, offer very peculiar technical features: canals for metallic dowels, cavities for marble tasselli and holes for also metallic staples or cramps. All these systems had the aim of reinforce a valuable material with potential structure problems. The ensemble is unique because of the preservation of a sufficient amount of fragments that allows their complete restitution with the help of photogrammetric techniques in order to obtain three-dimensional models of the pieces and to understand the ancient technologic solutions. Even more, the practices make us reflect about technical skills and economy and organization of constructions
