The vulnerability and seismic hazard of informal constructions located in highly seismic areas have been identified as the main causes of human and economic losses during high-magnitude seismic events in Peru. In addition, seismic risk studies determined that a large part of the city of Lima has non-engineering masonry dwellings that do not meet the requirements of technical design regulations. Therefore, the present study evaluates the influence of electrowelded wire meshes as a structural reinforcement for confined tubular masonry walls. In this sense, buildings of common use, of confined tubular masonry, located in the city of Lima and settled on very rigid soils, have been studied. A calibrated model has been determined that represents the capacity of the non-reinforced and reinforced confined tubular masonry walls. Non-linear static analysis has been performed to determine the capacity of the non-reinforced and reinforced confined tubular masonry structures and the reinforcement cost of each structure has been determined to determine the feasibility of the reinforcement. Finally, reinforcement has contributed to improving the seismic performance of tubular masonry structures confined to reasonable reinforcement costs.
