Influence of Salt Crystallization on Composites-to-Masonry Bond Evaluated on Site by Pull-Off Tests Open
A research, made in collaboration with Politecnico di Milano and University of Padua, has started with the aim of evaluating the influence of aggressive environmental conditions (moisture, temperature and soluble salts presence) on the bon…
Strategy for Integrated Surveying Techniques Finalized to Interpretive Models in a Byzantine Church, Mesopotam, Albania Open
The research is part of a larger project, within an international cooperation, supported by UNESCO, for the study, restoration, and revitalization of Byzantine and Ottoman monuments in Southern Albania. The project was carried out on the S…
Investigation of commercial ready-mixed mortars for architectural heritage Open

Methodologies for the evaluation of seismic vulnerability of complex masonry buildings: case histories in the historic centre of Sulmona Open
This paper describes a procedure, addressed to an articulated knowledge of the material, of the morphology and of the constructive aspects of the masonry structures, of the mechanical behaviour and of the possible failure mechanisms of com…
Importance of the geometrical survey for structural analyses and design for intervention on C.H. buildings: application to a My Son temple in Vietnam Open
The geometrical survey of the structure is of great importance in the case of historic buildings, being the base for the interpretation of structural damages, for the structural modelling and for the design of the intervention for preserva…

Diagnostic strategies for the repair intervention on churches damaged by earthquakes: the Toscolano Maderno Monumental Complex Open
This paper describes the methodology applied to two churches of the Garda area damaged by the 2004 earthquake in order to define the repair intervention. After interpretation of the damage causes, based on an accurate onsite survey and doc…
Creep behavior of masonry structures - failure prediction based on a rheological model and laboratory tests Open
Masonry, subjected to significant compressive stresses, tends to creep. This creep behavior is modeled using a rheological model, consisting of several basic springs and dashpots placed in series or in parallel. Qualitatively, this rheolog…
Study Of The Seismic Vulnerability OfComplex Masonry Buildings Open
The study of the seismic vulnerability of complex buildings belonging to a historical centre located in the Umbria region in Italy is presented here. The area was struck by an earthquake in 1997, which emphasized the high vulnerability of …
Testing and modelling of multiple-leaf masonry walls under shear and compression, Open
Predicting the behaviour of multiple-leaf masonry walls is a challenging issue, given the influence of a wide range of factors as the mechanical properties of the leaves, their dimensions and the way they are connected to each other. In th…
Prediction of the service life of brick/stone masonry damaged by salt crystallisation: application of a stochastic model Open
An attempt has been made within a EC Contract, to establish the maximum salt content in brick and \nstone masonry, below which the surface protection treatments do not fail. Crystallisation tests were \ncarried out on treated and untreated…
Deterioration of Masonry Surfaces and of Surface Treatments: Experimental Results on Full-Scale Models Open
Salt crystallization and frost-defrost action are among the most frequent causes of masonry decay. Surface treatments using advanced materials, like organic and inorganic resins, are being applied to existing and new masonry to provide pro…
Measurement of Grout Injection Efficacy for Stone Masonry Walls Open
For nearly a century, cementitious materials have regularly been injected into masonry structures in attempts to rehabilitate and retrofit them. Typical subjects for this treatment are multiple-leaf, stone walls characterized by poor bondi…
The Time-Dependent Behaviour of Masonry Prisms: An Interpretation Open
The experimental investigation which was carried out on the materials collected from the ruins of the collapsed Tower of Pavia in order to seek possible causes of the collapse, showed an interesting time-dependent behaviour of the multiple…
Characterization of Mortars and Plasters from Ancient Monuments of Milan (Italy) Open
Lime mortars have been sampled from ancient monuments of Milan. Some of their physical and chemical characteristics have been determined. Particularly interesting are lime mortars containing crushed and powdered bricks call “cocciopesto” m…
