Caratteristiche tipologico-strutturali per la valutazione della vulnerabilità sismica nel centro storico di Caltabellotta tra persistenze e trasformazioni
The research carried outin this paper aims at the knowledge of the typological and constructive characteristics of the building in Caltabellotta, in order to think about the seismic vulnerability. To achieve this goal, sheets were drawn up on the building types found and on the construction elements, looking for a method to overcome the difficulty of knowing the masonry due to the presence of plaster.
Numerical Modelling for Assessing the Structural Efficiency of CAM® Reinforcement System for Masonry Walls
A large portion of the Italian building heritage is made of masonry construc-tions, which were erected in the first decades of the last century and were conceived to support gravitational loads only. Many research activities have been carried out in order to propose retrofitting techniques aimed at improving seismic behaviour of existing ma-sonry buildings. The present paper focuses on the CAM® reinforcing system. Such a retrofitting technique, which is widely used in Italy, consists in the application of pre-tensioned stainless steel ribbons on existing masonry walls, conferring to them addi-tional strength, ductility and beneficial confinement effects. The preliminary outcomes of a common…
Esposizione e vulnerabilità sismica dell'edilizia residenziale del centro storico di Caltabellotta
Aiming at evaluating the seismic vulnerability of the old town of Caltabellotta, first the main characteristics of the new survey cards CARTIS for the structural typology characterization recently developed, and the bases of the macroseismic method for seismic vulnerability and fragility curve estimation, are briefly summarized. Then, the main typological and structural characteristics of the house typology in the historic centre of Caltabellotta are described, providing a synthetic estimate of the vulnerability and highlighting the probability of reaching predetermined levels of damage in relation to the intensity of the expected earthquake (fragility curves). This information, combined wi…
