Diseño de un puente vehicular sobre el “Río Anzu” en la vía El Rosal – Simón Bolívar, parroquia Fátima, cantón Pastaza, provincia de Pastaza, utilizando la normativa AASHTO LRFD 2020

Abstract

In the province of Pastaza, along The Rosal – Simon Bolivar Road, there is no adequate bridge over the Anzu River to connect the Simon Bolivar community, which belongs to the Fatima parish. This lack of proper infrastructure has limited the mobility of the local population and has negatively impacted on the commercialization of their agricultural and artisanal products. The existing bridge is structurally deficient and not suitable for heavy traffic, which has contributed to a decline in the parish’s economic activity. This study proposes the design of a steel bridge with a reinforced concrete deck as a viable solution to improve connectivity and stimulate economic development in the area. The project includes the collection and analysis of technical data required for the design, such as hydrologic, topographical, and geotechnical studies, which were obtained from the MTOP and complementary sources. Considering thar the proposed bridge will have a total span of 73 meters, and in accordance with the AASHTO LRFD 2020 standard, which allow spans of up to 100 meters without intermediate supports.
