    Análisis de los desplazamientos de los apoyos superiores de las torres durante la simulación de las fases de construcción de un puente colgante sobre el río Jatun Yacu

    This research addresses a topic rarely explored in technical literature: the analysis of the behavior of upper tower supports in suspension bridges, both during the construction process and in their service life. This lack of practical information motivated the development of a study based on a real-world project, aiming to simulate near-reality conditions and obtain reliable data on the displacements generated by the weight of the structural elements. To address this problem, an applied research was conducted using a real suspension bridge project. The main objective was the development of a threedimensional model using specialized software, which allowed for the simulation of various construction phases of the superstructure, as well as the application of a hypothetical and random load convoy to evaluate in-service behavior. The analysis allowed for the observation of stresses in the main cable and the resulting displacements, identifying that the sum of movements generated during construction and by vehicular load exceeded the available travel in the upper supports. Given this situation, it was necessary to iteratively apply a pre-stress to the main cable in the lateral zones of the bridge to correct the structural behavior. Finally, after adjusting the initial cable deformation as pre-stress, it was validated that the displacements during the construction and operation phases remained within acceptable limits, ensuring the correct functioning of the upper supports and the overall suspension bridge structural system

    Determinación de las técnicas de reforzamiento para mejorar el desempeño estructural de un edificio mixto
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Civil, 2016) Jácome Villacrés, Pablo José; Mora Mora, Miguel Ángel
    This investigation Project, has been done to know the different options of structure reinforcement and focus in one of them to be analyze. This investigation project has a Critical-Purposeful Paradigm. Analyze present condition of a mixed construction building and the reaction front a seismic event. The principal object of this purpose is find a solution to the problem and the advantages of the reinforcement, The methodology of investigation is based in a bibliographic to add new knowledge about this investigation theme. The used methods are structure evaluation, sclerometrics trial, structure analyze and reinforcement using FRP system (Fiber Reinforcement whit Polymers), all of them important in the conception of this investigation. There are conclusions and recommends based in the referential materials like codes and software for reinforcement and evaluations of structures. The product is a project to reference the futures investigations.
