Lecciones estructurales del sismo del 16 de abril del 2016, para mejorar el diseño y construcción de futuros puentes, utilizando el puente de Mejía ubicado en la provincia de Manabí como ejemplar de estudio

Abstract

Abstract: The devastating earthquake of April 16, 2016, in Ecuador revealed critical vulnerabilities in our road infrastructure, highlighting the urgent need to strengthen seismic engineering practices to protect the population. This study focused on the Mejía Bridge (Manabí) as an exemplary case, seeking to extract vital structural lessons. Through analysis of technical data, field observations, and consultations with experts, key deficiencies were identified. The inadequate configuration of the metal DECK and poor connections reduced the inertia and load-bearing capacity of the bridge. Additionally, soil liquefaction contributed to severe damage. The findings allow for recommendations to optimize the design and construction of future bridges, covering improvements in the metal DECK, robust connections, and advanced geotechnical considerations. Implementing these guidelines is essential to enhance the resilience and safety of our roads, ensuring that the infrastructure supports the social development of the Ecuadorian people in the face of seismic adversity.
