ABSTRACT The repair of historical masonry columns damaged by earthquakes is a complex engineering procedure. In most cases, these elements support important vertical loads, and, for this reason, the repairing interventions (such as block replacement) could generate critical modifications of the stress pattern and eventually lead to local failures of the masonry material. In order to prevent critical

ABSTRACT A simple methodology for seismic assessment of masonry building, which allows the ranking of the seismic safety of buildings according to principles and rules that are established in Part 3 of the Eurocode 8 (EC8), is presented in this work. This approach uses the concept of “performance curve”, which consists in the representation of all possible performance points (the target displacements

ABSTRACT Auguste Fabre was a French contractor specialized in the construction of masonry vaults. He founded his company in 1896 and patented different systems of light and economic vaults, among them one for tile vaults.
