Análisis de resistencia de un puente vehicular de acero estructural en arco con tablero intermedio considerando la normativa aashto lrfd

Abstract

Civil works and infrastructures satisfy the needs of the community, having to bear loads and the passage of time; therefore, they require maintenance by guaranteeing their stability, especially the bridges that interconnect strategic points; At the Technical University of Machala there is a bridge for vehicular entry built in steel with a concrete deck, facilitating access from Avenida 25 de Junio to the interior of the university campus; However, due to lack of maintenance, it has deteriorated over the years, putting both drivers and pedestrians at risk, making this study necessary when structurally analyzing the bridge using SAP 2000 software to verify if it requires an intervention or is still compliant. with the design criteria of the ASSHTO LRFD regulations. For the respective study and subsequent analysis of the results, it will be necessary to take into account the guidelines established in the Ecuadorian Road Standard-NEVI 12 MTOP and the Ecuadorian Construction Standard-NEC. In the results, the resistance of the hollow circular section HSS elements is detailed, relating their demand and capacity to know the percentage at which each element is working and based on this determine the necessary corrective measures and intervention in order to safeguard the integrity of those who use it daily.
