In case of existent masonry building, the definition of reliable mechanical parameters could be a very difficult task to be achieved. For this reason, an estimation of these values is useful, for example it is the first phase of the knowledge process, for simplified mechanical model or when NTD test is the only possibility.The transversal connection in masonry panels is a technological detail that affects the static and seismic behavior and could significantly increase the strength of the element.In this paper the effect of transversal connection in double-leaf brickwork masonry panels is evaluated by diagonal compression tests. To achieve this goal, a new set-up was designed to load each leaf independently.The results have shown an increment of about 20% in strength if transversal connection is present. If the leaves have very different mechanical parameters, the tests highlight an unexpected beh...

It focuses on validation and improvement of Risk-UE LM2 capacity curves for unreinforced brick masonry (URM) buildings, with stiff floors and reinforced concrete (RC) shear wall buildings. Given that the standardized Risk-UE capacity curves have been mainly developed for building stock of southern European cities, their reliability for different building features is validated. Within the framework of the development of seismic scenarios for the two cities, a detailed survey was performed for a sample of 500 buildings. Individual capacity curves were determined for all buildings, following the DBV simplified approach. Specific typological classification has been proposed for the Swiss built environm...

The vulnerability model connected to the survey methodology provides an evaluation of the expected mean damage. Comparison with the observed damage determined the
