Diseño y simulación de un puente colgante mixto de 110m de longitud y 4.5m de ancho para vehículos livianos de máximo 1000kg.

Abstract

The objective of this project was the design and simulation of a suspension bridge with a wooden floor located in an arm of the sea between the cantons of San Lorenzo and Tambillo. This is because the communication between the two populations is by sea, being a very time-consuming alternative to connect the two cantons. It was proposed to build a suspension bridge with two main beams joined by secondary cross beams and supported by cables. Additionally, the structure to be used was built with A36 steel beams, due to the fact that it is a commercial material and has a good admissible effort. A50 steel cables were used, which provide strength and stability to the structure, giving a minimum deflection movement. The data obtained in a simulation carried out in the SAP 2000 program were analyzed, which indicated that the project is admissible in efforts and deflections. It was placed with a board made of wood for the bridge road, this in order to reduce the cost of materials to be used. The wooden floor was anchored with wooden beams on the metal structure. On these beams the wooden floor is anchored with 4 cm planks. It was recommended to place safety railings built with 2-inch diameter galvanized tubes. This bridge benefited the towns of San Lorenzo and Tambillo for the commercialization and mobility of the inhabitants.
