Accelerated optimization method for low-embodied energy concrete box-girder bridge design

Penadés-Plà, Vicent; García-Segura, Tatiana; Yepes, V. (Elsevier, 2019)

[EN] Structural optimization is normally carried out by means of conventional heuristic optimization due to the complexity of the structural problems. However, the conventional heuristic optimization still consumes a large ...
CO2-Optimization of Post-Tensioned Concrete Slab-Bridge Decks Using Surrogate Modeling

Yepes-Bellver, Lorena; Brun-Izquierdo, Alejandro; Alcalá-González, Julián; Yepes, V. (MDPI AG, 2022-07)

[EN] This paper deals with optimizing embedded carbon dioxide (CO2) emissions using surrogate modeling, whether it is the deck of a post-tensioned cast-in-place concrete slab bridge or any other design structure. The main ...
Computer-support tool to optimize bridges automatically

García-Segura, Tatiana; Yepes, V.; Alcalá González, Julián (WIT Press, 2017)

[EN] In bridge design, many variables like material grades, cross-sectional dimensions, passive and prestressing steel need to be modeled to evaluate structural performance. Efficiency gains are intended while satisfying ...
Diseño estructural del puente sobre la rambla de Artaix en el proyecto de desdoblamiento de la CV-35, en el término municipal de Casinos (Valencia)

Cámara Pérez, Alexandre (Universitat Politècnica de València, 2020-09-18)

[ES] Se abordará el diseño de un puente tipo losa de hormigón postesado, que ya ha sido proyectado por la empresa IDOM adoptando la solución de vigas prefabricadas. En el caso de este TFM, el puente se resolverá con una ...
Efficient design of post-tensioned concrete box-girder road bridges based on sustainable multi-objective criteria

García Segura, Tatiana (Universitat Politècnica de València, 2016-11-03)

[EN] Bridges, as an important component of infrastructure, are expected to meet all the requirements for a modern society. Traditionally, the primary aim in bridge design has been to achieve the lowest cost while guaranteeing ...
El legado de Ricardo Barredo

Fenollosa Forner, Ernesto Jesús; Cabrera Fausto, Ivan; Llopis-Pulido, Veronica (Departmento de Publicaciones del CSIC, 2023-06)

[ES] Ricardo Barredo de Valenzuela fue una figura clave en el desarrollo tecnológico de la construcción en España en la primera mitad del siglo XX. Dirigido por Eduardo Torroja, desarrolló un método de postesado de estructuras ...
Estudio y caracterización de las estructuras laminares de hormigón armado en la Comunitat Valenciana

Arnau Paltor, Fernando Amadeo (Universitat Politècnica de València, 2021-10-13)

[ES] Las láminas de hormigón armado utilizan principalmente su forma como meca-nismo resistente. Son estructuras extremadamente eficientes y bellas. El desarrollo de este tipo de estructuras se inicia en torno a los años ...
Hybrid harmony search for sustainable design of post-tensioned concrete box-girder pedestrian bridges

García Segura, Tatiana; Yepes Piqueras, Víctor; Alcalá González, Julián; Pérez López, Eloy (Elsevier, 2015)

This paper aims to find sustainable designs of post-tensioned concrete box-girder pedestrian bridges. A hybrid harmony search algorithm combining threshold optimization is used to find the geometry and the materials for ...
Lifetime reliability-based optimization of post-tensioned box-girder bridges

García Segura, Tatiana; Yepes, V.; Frangopol, D.M.; Yang, D.Y. (Elsevier, 2017)

[EN] This paper presents a lifetime reliability-based approach for the optimization of post-tensioned concrete box-girder bridges under corrosion attack. The proposed approach is illustrated by determining the optimal ...
Multiobjective optimization of post-tensioned concrete box-girder road bridges considering cost, CO2 emissions, and safety

García Segura, Tatiana; Yepes, V. (Elsevier, 2016-10)

This paper presents a multiobjective optimization of post-tensioned concrete road bridges in terms of cost, CO2 emissions, and overall safety factor. A computer tool links the optimization modulus with a set of modules for ...
Optimization of high-performance concrete post-tensioned box-girder pedestrian bridges

Yepes, V.; Pérez-López, E.; García-Segura, Tatiana; Alcalá-González, Julián (WITPress, 2019)

[EN] This paper deals with the economic optimization of high-performance post-tensioned concrete box-girder pedestrian bridges. To this end, a program analyzes and evaluates the structural restrictions following Spanish ...
Parametric study of concrete box-girder footbridges

Yepes, V.; Pérez-López, E.; Alcalá, J.; García-Segura, T. (Dynamic Academy Yazilim, 2018)
