ABSTRACT
The aim of this paper is the analysis of the behaviour of brickwork masonry walls damaged by shear-bending loading and reinforced by Carbon Fibre Polymers.
The composite materials, FRP, applied at the surface of masonry permit acquiring tensile capacity and to avoid the cracking as a consequence of tensile weakness. In particular, masonry buildings may be damaged by seismic action that induces a tensile stresses. A typical failure of a masonry wall subjected to shear force is a flexural failure characterised by cracking at the tensioned side or crushing of masonry units at the compressed zone of wall.
In this paper the author exams this case of failure considering experimental brickwork masonry models in 1 to 2 scale. After damage the brickwork model was reinforced by CFRPsheets and subjected to the same path of loading. The experimental results obtained by the tests on the brickwork models are reported. Finally the comparison between the data of unreinforced and reinforced models leads to a number of considerations on the use of CFRP in repair works of masonry buildings.
Key words: masonry model, shear-bending test, strengthening, CFRP-sheets.
