The present professional sufficiency project develops a comparative analysis of the structural behavior of reinforced masonry walls in stations E-18 and E-19 of Lima Metro’s Line 2. These walls play a crucial role in transportation infrastructure as they must support both the dead loads from the structure and the live loads generated by the constant flow of passengers and the continuous operation of trains. This research is oriented toward identifying the optimal structural configurations for these walls, ensuring their durability and stability under high operational demand conditions. Previous studies highlighting the use of reinforced masonry walls in urban transportation systems are considered as background, yet there remains an opportunity for specific study under the unique loading conditions in these stations. In this context, the present work aims to evaluate the structural behavior of these walls under different loads, identify optimized configurations in terms of strength and safety, and formulate recommendations to improve the design for future projects in urban transportation systems. In developing the solution, a specific design is proposed for the P19-type reinforced masonry walls, selecting their height, thickness, and construction materials in compliance with regulatory standards. This design includes additional reinforcements in high-stress areas to ensure structural performance under the required loads. ETABS simulations allow the modeling of the walls' behavior under acting loads and the determination of necessary reinforcements. Additionally, the project presents an optimization of the steel quantity used, reducing reinforcement without compromising structural safety. This optimization results in decreased costs for materials and labor, contributing to greater efficiency in project execution. The validation of the optimized design shows that it meets regulatory and structural requirements. The comparison between the initial design and the optimized design demonstrates that the latter allows a considerable cost reduction, simplifying the assembly and execution of the walls without affecting their safety or functionality. The cost analysis conducted supports this conclusion, demonstrating the economic feasibility of the proposed improvements. Finally, the study demonstrates that reinforced masonry walls, designed and reinforced according to technical standards and structural simulations, represent an effective and efficient solution for metro stations under high load demands. It is recommended that the findings obtained in this research be applied in future urban infrastructure projects to promote safe, efficient, and sustainable constructions.
