VOLUME 2 - Masonry Structures

In this volume, through pictures, diagrams, technical reports, are illustrated all the applications that TEC.INN. has performed since 1995 till today on masonry structures (natural stone, masonry, etc,) with particular evidence to previous, contemporary and following installation testing activities, performed firstly to know the structure in need of retrofit, then to control the status of progression of the works and finally, once all the works have been completed, to validate the performance, quality and effectiveness of the retrofit application. The examples reported regards structures and infrastructures of historic-artistic-monumental value and also about buildings strengthened after the earthquake shock of 1997 happened in the regions of Umbria and Marche.
The volume describes then applications varying from FRP (carbon, glass as well as aramid fibers) applications on the frescoed cupolas of the cathedral of Città di Castello in 1996, the column confinement of the marble panels of the Maggiore Fountain in Perugia, the cupola confinement of the Cathedral of Urbino and nevertheless strengthening of the Italy’s Bank in Rome.
In the volume are described and illustrated many other jobs about strengthening works where TEC.INN. has been involved, regarding structures in need of strengthening, confinement not only of single columns but of the entire structure, historic structures as well as not, also performed under the works prescribed for security reasons after the earthquake of 1997.
Antonio Nanni, Ph.D., P.E., comments with these words the volume: “It is a rich collection of retrofit and strengthening applications on historic and civil masonry structures, for the most damaged by earthquakes shocks. The common aspects among all reported jobs is the restoration of the masonry element, being either a vault, an arch, a column, a wall, as it is in the tradition of the “master builders” of a time. The reader will discover that at the moment for many of the presented case studies, no available technologies could possibly substitute the one of FRP.
