The behavior of stone masonry panels strengthened with high strength steel cords is experimentally studied and presented in this paper. It is proposed by the authors for the reinforcement of masonry structures including those made with irregular elements when the facing stone surface must be kept. The technique consists of embedding a continuous mesh of high strength steel cords in the mortar joints, the nodes of which are anchored to the wall by means of transversal metal bars. The technique is proposed either in addition to other possible techniques or by itself, separately. Experimental results and applications of the technique have shown positive characteristics and the results of tests carried out on site show, in some cases, increases in shear and compression strength and stiffness of the masonry walls.

Abstract
The behavior of stone masonry panels strengthened with high strength steel cords is experimentally studied and presented in this paper. It is proposed by the authors for the reinforcement of masonry structures including those made with irregular elements when the facing stone surface must be kept. The technique consists of embedding a continuous mesh of high strength steel cords in the mortar joints, the nodes of which are anchored to the wall by means of transversal metal bars. The technique is proposed either in addition to other possible techniques or by itself, separately. Experimental results and applications of the technique have shown positive characteristics and the results of tests carried out on site show, in some cases, increases in shear and compression strength and stiffness of the masonry walls.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
