Estudio del comportamiento ante carga lateral de pórticos de acero rellenos con panel de mampostería y reforzados mediante la técnica del enchapado : evaluación técnica y económica de un pórtico con relleno de mampostería sin reforzar, con las conexiones entre viga y columna soldadas y en otros apernadas, donde se le aplica un daño previo moderado a la mampostería y luego se refuerza con malla electrosoldada y sometido a cargas laterales cíclicas.

Abstract

The present work of curricular integration has the purpose of carrying out the comparison of steel frames filled with masonry and reinforced by the veneer method, through the bibliographic review of tests previously carried out on these topics. Reinforcement by the veneer method consists of placing an welded mesh on each face of the masonry and anchoring it to the surrounding frame, to later be covered by a layer of low-resistance mortar. To carry out the study, data from two prototypes reinforced by veneer after having been slightly affected have been used. The first prototype is made up of RCFT columns and IPE beam joined by welded connections and the second is made up entirely of IPE profiles with bolted connections. In addition, an economic analysis of this type of reinforcement is presented, through which the cost per square meter of this reinforcement is obtained. On the other hand, as one of the results, an easy-to-understand construction guide is presented so that reinforcement by the veneer method can be applied in the engineering field. Finally, the experimental results of the reinforcement were compared with its empty frame and masonry frame variants, in parameters such as ultimate capacity, stiffness degradation and energy dissipation, to quantify the increase in these values after reinforcement.
