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 ...
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 ...
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 ...
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)

[EN] This paper presents a study of the parametric variability of post-tensioned concrete box-girder pedestrian bridges. SAMO2 algorithm is used for the parametric study. This algorithm combines SA with a mutation operator, ...
Robust decision-making design for sustainable pedestrian concrete bridges

Penadés-Plà, Vicent; Yepes, V.; García-Segura, Tatiana (Elsevier, 2020-04-15)

[EN] In recent years, there is a trend toward the construction of sustainable structures. The goal of sustainability in structures involves several criteria that are normally opposed, leading to a decision-making process. ...
Robust Design Optimization for Low-Cost Concrete Box-Girder Bridge

Penadés-Plà, Vicent; García-Segura, Tatiana; Yepes, V. (MDPI AG, 2020-03)

[EN] The design of a structure is generally carried out according to a deterministic approach. However, all structural problems have associated initial uncertain parameters that can differ from the design value. This becomes ...
