The main objective of this study was to establish, in a precise and detailed manner, the necessary guidelines for the design of the Tahuayo Bridge, which collapsed in 2021 due to heavy rains associated with the El Niño phenomenon, common in the Andean region of Peru in recent years. With a length of 25 meters, the bridge requires a robust and well-designed structure to withstand gravitational and live loads, such as those generated by the HL 93 design truck, according to AASHTO standards. The methodology involved applying AASHTO guidelines to determine load demands, both gravitational and traffic-related. The CSI Bridge software was used for structural design, supplemented by manual calculations to verify the results. The analysis revealed the need for reinforced concrete beams with a depth of 1.75 meters and a base of 55 centimeters, reinforced longitudinally with 28 one-inch diameter bars. Additionally, it was determined that half-inch diameter stirrups with two legs, spaced no more than 15 centimeters apart at the supports, are required for transverse reinforcement. Regarding deflections and service conditions, it was concluded that the proposed design adequately complies with the applicable standards, ensuring the safety and stability of the bridge under normal usage conditions. This study provides a valuable guide for the design and construction of similar structures in the region.
