Implementación de puente peatonal con preesforzado sobre avenida ferroviaria a la altura del Centro de Salud Velasco Ibarra en Machala

Abstract

Through this degree work, an existing problem on the railway avenue at the height of the Velasco Ibarra health center, in the city of Machala, province of El Oro, is made known. Since, with the urban growth of the railway avenue, it has generated great traffic demand, this leads citizens to put their lives at risk to cross the road. To solve this problem, it is proposed to design the superstructure of a pedestrian bridge with prestressed concrete, which must be accessible for people with limited mobility, for that, it is proposed to place two elevators at each end of the bridge. For the pedestrian bridge, a double T beam is designed, 32.50 m. long and 2.30 m. wide, capable of supporting the loads that were obtained based on a pre-design, which we have loads in plant, self-weight load of 6.36 KN/m, loads in work ,overloads of 1.295 KN.m, and finally when in service, live load of 5.52 KN.m. The calculations are governed by the following standards. - INEN and MTOP for the design of roads in the country. - AASHTO for bridge design with prestressed concrete.
