Sesión temática en CMN2021: Optimization, metaheuristics and evolutionary algorithms in civil engineering

En el marco del próximo congreso CMN2021 (Congress on Numerical Methods in Engineering) que se celebrará en Las Palmas de Gran Canaria del 28 al 30 de junio de 2021, hemos organizado una sesión temática coordinada por David Greiner, Diogo Ribeiro y Víctor Yepes que versa sobre optimización, metaheurísticas y algoritmos evolutivos en ingeniería civil. Os dejo a continuación una breve descripción del congreso y un resumen de la sesión temática propuesta.

El objetivo del Congreso de Métodos Numéricos en Ingeniería (CMN) es actuar como un foro en que se recopilen los trabajos científicos y técnicos más relevantes en el área de los métodos numéricos y la mecánica computacional, así como sus aplicaciones prácticas. CMN 2021, organizado conjuntamente por las sociedades de métodos numéricos española (SEMNI), portuguesa (APMTAC) y por el Instituto Universitario de Sistemas Inteligentes y Aplicaciones Numéricas en Ingeniería (SIANI) de la Universidad de Las Palmas de Gran Canaria (ULPGC). Los anteriores congresos conjuntos de ambas sociedades fueron celebrados en Madrid (2002), en Lisboa (2004), en Granada (2005), Porto (2007), Barcelona (2009), Coimbra (2011), Bilbao (2013), Lisboa (2015), Valencia (2017) y Minho (2019). Habiendo sido Las Palmas de Gran Canaria la sede del Primer Congreso CMN organizado por SEMNI en 1990, (General Chairs: Gabriel Winter y Miguel Galante), retorna 31 años después a su primera sede. El programa científico del CMN 2021 estará estructurado en sesiones temáticas según las distintas especialidades de los métodos numéricos. Las comunicaciones presentadas en el congreso constituirán una referencia de los avances recientes y de las líneas de trabajo futuras. Asimismo, investigadores internacionales de reconocido prestigio impartirán una serie de conferencias plenarias. El enlace a la web del congreso es la siguiente: https://congress.cimne.com/cmn2021

Técnicas de optimización avanzada y sus aplicaciones a la ingeniería civil

Tal y como os comenté en un post anterior, un grupo de profesores decidimos lanzar un número especial sobre optimización avanzada en la revista Advances in Civil Engineering (indexada en el JCR). El enlace, en abierto, al contenido de este número especial lo podéis ver aquí: https://www.hindawi.com/journals/ace/si/893072/

Sustainable assessment of retaining walls through an active learning method considering multiple stakeholders

ABSTRACT: The sustainability approach has changed the modern society. Currently, the sustainability takes into consideration, not only the economic and environmental facets, but also the social facet. Taking into account the three facets of sustainability, this paper shows the application of a method of active learning to assess the sustainability of three real retaining walls. A group of 29 students of the Master of Science in Planning and Management in Civil Engineering at the Universitat Politècnica de València has experienced this assessment. The method followed was proposed by academics of the School of Civil Engineering of the Universitat Politècnica de València (Spain) and Universidad de La Frontera (Chile). An approach multi-criteria and a clusters analysis are part of method, which allows developing a participative process with different points of view about the sustainability. The outcomes show that of this way students can forecast impacts from of the integration of design, planning and the location context of the infrastructure. Result evidence that personal values of each student influences the election of the optimal alternative. The paper also identifies the need to strengthen the conceptualization of social criteria in the students training.

Special Issue on Advanced Optimization Techniques and Their Applications in Civil Engineering

Civil Engineers are involved with the creation, monitoring, and management of infrastructural resources, as well as the e›cient, economic utilization and management of renewable natural resources. Nowadays a rapid growth of computer performance enables and encourages new developments in civil engineering as well as related areas. For instance, the construction industry investigates new designs with minimum cost, minimum CO2 emissions, or embodied energy, among other objectives. Conventional optimization techniques are usually inadequate to nd best designs by taking into account all design variables, objectives, and constraints in the complex civil engineering problems. Applications of optimization techniques are most exciting, challenging, and of truly large scale when it comes to the problems of civil engineering in terms of both quality and quantity. In order to overcome the di›culties, researchers are interested in advanced optimization techniques. In the recent literature, researchers have applied the advanced optimization techniques to dišerent purposes.

The aim of this special issue is to collect the studies using optimization algorithms in civil engineering problems such as structural engineering, construction management, and environmental engineering. Potential topics include but are not limited to the following: Intelligent optimization Swarm and evolutionary optimization techniques Single and multiobjective optimization Predictive modeling and optimization Computational complexity and optimization Continuous or discrete optimization Structural optimization Size, shape, and topology optimization New design optimization applications in civil engineering New and novel approaches and techniques for solving optimization problems in civil engineering New research in any areas closely related to optimization and civil engineering designs Authors can submit their manuscripts through the Manuscript Tracking System at http://mts.hindawi.com/submit/journals/ace/otace/

Towards sustainable civil engineering works using precast concrete solutions

CV ARTICULOMost of the achieved advances related to define standardized methodologies to quantify the contribution to “sustainabilize” the construction are linked to buildings rather than infrastructures, and much more in particular to housing. Global impact on housing is the widest and highest one, gathering the three sustainable axis: environmental (greenhouse gas emissions derived from heating or cooling to reach indoor comfort  conditions), social (home is a basic need for families) and economic (it usually represents the main expense over the life of people). Meanwhile civil engineering work has not evolved as long on this topic. Although we generally refer to greater constructions, sustainable impacts are more diffused and don´t have such a direct repercussion into the citizens and daily life. For this reasons, there are not as many assessment methods for civil engineering works as there are for buildings, or even any literature regarding this field. Therefore it may implies a technical and promotional handicap to promote a higher use of precast concrete elements in a sort of constructions governed by engineers that usually appreciate better their performance advantages. This article pretends to describe the strengths that precast concrete construction will have into the upcoming standards for civil engineering works, in order to enhance their possibilities to reach a greater market share. Sustainable indicators on current draft standards will be assessed.
