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 reforzada con malla electrosoldada sin daño previo, con las conexiones entre viga y columna soldadas y en otros apernadas, sometido a cargas laterales cíclicas.

Abstract

The main objective of this Curricular Integration Work is to technically compare two lateral load-tested prototypes in undamaged masonry reinforced through veneered. In one case, the connections between the beam and column will be welded, while in the other case, they will be bolted. Additionally, an economic analysis of this reinforcement approach will be conducted. Prototype 1 will feature RCFT column sections and IPE beams, whereas Prototype 2 will solely consist of IPE profiles for both beams and columns. Both prototypes will be reinforced using veneered technique, which involves anchoring an-electro-welded mesh on both faces of the masonry panel, coated with mortar. This approach ensures proper force transmission between the frame and the mesh. By means of a bibliographic review of previous tests conducted on these prototypes and through modeling using the SeismoStruct software for an empty frame, parameters such as displacement, drift, capacity, stiffness, and energy will be compared. Furthermore, a reference budget per square meter for cladding-based reinforcement will be established, employing a Unit Price Analysis (UPA) methodology and considering material and labor costs from the year 2023 in the city of Quito. In addition, a description of a structural modeling guide will be incorporated, providing a foundation for designing this type of reinforcement within SeismoStruct.
