NUMERICAL ASSESSMENT OF THE OUT-OF-PLANE RESPONSE OF MASONRY PANELS REINFORCED BY MEANS OF FRCM SYSTEMS

Abstract eng:
The use of Fibre Reinforced Cementitious Matrix (FRCM) materials, is becoming a very common technique of retrofitting for historical and monumental masonry buildings. This technique, if compared to the use of fiber polymeric materials (FRP), is more compatible with the mechanical property of the masonry and more appropriate with the preservation needs of cultural heritage, associated to the historical constructions. The effectiveness of such a type of reinforcement for improving the out-of-plane seismic capacity of masonry walls, in comparison with traditional reinforcements with steel tie-bars, was investigated in a previous experimental campaign. In the present work, a macro-modeling approach, already available in the literature for modeling masonry structures with plane and curved geometry, was used to predicting the out-of-plane response of masonry structures reinforced by means of FRCM. The model was validated by mean of the simulation of the previous cited experimental tests.
