JATIVA, Jefferson; TORRES, Ivett2; HERNANDEZ, Luis  e  AREVALO, Diego. Study of the Reinforcement of Concrete Block Masonry through Destructive Tests Applied to Steel Frames with Bolted Joints. Rev Politéc. (Quito) [online]. 2023, vol.51, n.2, pp.87-98. ISSN 2477-8990.  https://doi.org/10.33333/rp.vol51n2.08.

This study is based on the fact that there is little literature on the intervention of steel frame structures in which masonry infills are given a structural function from a seismic-resistant approach. However, an intervention strategy for masonry structures is a priority to prevent and mitigate seismic risk and reduce human losses. For this reason, a structural intervention system called enchape is presented. This system was applied in two prototypes of steel frames designed and built with a prequalified beam-column connection Bolted Flange Plate (BFP) and infill masonry to test them in three study scenarios through the application of cyclic lateral load in the laboratory and applying the type 1 protocol established in FEMA 461. For this purpose, materials and geometries used in construction were selected to develop a methodology for both construction and testing under laboratory conditions. By means of this work, the behavior of these prototypes when subjected to a cyclic lateral load is known, in this way a reinforcement methodology applicable to steel structures with masonry infills without seismic affectations and rehabilitation for those that have suffered some damage in their post-earthquake masonry is proposed.
