Diseño y simulación de un puente metálico de 60 metros de luz y 12 metros de ancho para una capacidad de carga de 90 toneladas

Abstract

This thesis aims to design and simulation of a metal bridge, under the application of load and resistance factors design method (LRFD). To calculate the bridge has been considered the standard specification AASTHO 2010. We calculated the bending moment and shear due to the loads acting on the superstructure, giving a moment and maximum shear force or service that was designed with the beam type metal “I” . To avoid the drift of the superstructure was designed diaphragms. The union of the concrete slab with steel beams was performed using the shear connectors type ¨ C ¨. SAP 2000 Software simulation allowed to determine the bridge, the results obtained through it, were compared with manually calculated results. We determined costs by providing materials and fabrication of structural elements of the superstructure. The project plans contain details of design and manufacture of metal components of the superstructure.
