- Description
- Repair of historic masonry by Fiber Reinforced Polymers (FRP) systems is being more and more used especially in seismic areas. A rather great deal of experimental research on the mechanical behaviour of the repaired masonry has been carried out but very small experimental work has been done on the durability of FRP repairs when masonry is exposed to aggressive environments.
Carbon FRP (CFRP) have been applied on the surface of both soldier course and running bond
specimens respectively as bonds in thin vaults and in solid walls. A total number of 20 specimens have
been prepared and tested. A RILEM pre-standard procedure was followed for the evaluation of resistance to sulphates of the specimens. The damage evolution has been monitored by visual
observation and by quantification of material loss in the vertical section at each 4 week cycle and the
first results are here reported which show the importance of a carefulr application of FRPs.

- Description
- The sudden collapses in Italy (Civic Tower of Pavia 1989, Noto Cathedral, 1996) initiated the research into long term behaviour of historical masonry structures. Last decade, international ad hoc collaboration was established within several research inatitutes in Europe. The testing on masonry samples identified the creep behaviour as a possible cause of the collapse of historical masonry buildings. Secondly, research focused on the study of the factors affecting creep (rate of loading, stress level,..) and efforts were made to set up the most suitable testing procedures to understand the phenomenon. The gained insight in the long term behaviour and its description by means of rheological models, is validated mainly by means of long term testing, identifying significant parameters (strain rate of secondary creep phase, damage parameters…).

- Description
- A valid approach for the limit analysis of existing masonry buildings in seismic areas concerns the application of single or combined kinematics models involving the equilibrium of structural macroelements. They can be more reliable in describing the real structural behaviour than common equivalent static procedures, based on the “box” behaviour of the structure and on the elasto-plastic behaviour of the
masonry. The main results of the application of different procedures for the static analysis of masonry buildings in seismic area are discussed in the paper. Urban centres suffering different levels of damage and different typologies of buildings are compared.
