Avances científicos en relación con los edificios prefabricados de hormigón sismorresistentes

Acaban de publicarnos un artículo en Structures, revista indexada en el JCR. El trabajo lleva a cabo un análisis exhaustivo de 127 artículos para identificar las tendencias predominantes y las brechas actuales en la investigación sobre edificios prefabricados de hormigón (PCB) resistentes a los terremotos. Estos edificios ofrecen ventajas como la rapidez de construcción, la mejora de la durabilidad y la reducción de la mano de obra, pero es necesario estudiar las conexiones entre los elementos prefabricados para garantizar su resistencia sísmica.

El estudio se enmarca dentro del proyecto de investigación HYDELIFE que dirijo como investigador principal en la Universitat Politècnica de València.

Entre otras, se pueden destacar las siguientes contribuciones del trabajo:

  • Reveló la correlación entre los PCB y temas como las conexiones secas, la disipación de energía, el diseño óptimo y el colapso progresivo, lo que puso de relieve la naturaleza diversa de las investigaciones actuales en este campo.
  • Identificaron los sistemas de marcos y pantallas de rigidización como las categorías predominantes en la investigación de los PCB, siendo el enfoque tradicional de construcción moldeada in situ la referencia para determinar su rendimiento sísmico.
  • Destacó la necesidad de explorar con mayor detalle sistemas estructurales innovadores y resilientes y de adoptar metodologías de vanguardia para integrar la seguridad sísmica y la sostenibilidad de los PCB.
  • Proporcionó una hoja de ruta para futuros proyectos de investigación e informó sobre los últimos avances y tendencias en la investigación de PCB con seguridad sísmica.

Abstract:

Precast concrete buildings (PCB) offer several advantages, including swift construction, exceptional quality, enhanced durability, decreased formwork requirements, and reduced labour. However, it is crucial to effectively study the connections between the various prefabricated elements that make up the structure, particularly in the face of dynamic loads and seismic actions. Extensive research has been conducted to develop seismic-resistant PCB, underscoring the necessity of exploring research approaches, identifying trends, addressing gaps, and outlining future research directions. A thorough analysis was carried out on a literature set comprising 127 articles published between 2012 and May 2023, using a three-step research process that included bibliometric search, quantitative analysis, and qualitative analysis. The primary objective was to identify prevailing research trends and pinpoint current gaps that would contribute to the advancement of future research. The scientific mapping of authors’ keywords revealed the correlation between PCB and topics such as dry connections, energy dissipation, optimal design, and progressive collapse, highlighting the diverse nature of current research in the field. Furthermore, the qualitative literature analysis demonstrated that frame and shear wall systems emerged as the predominant categories. This dominance can be attributed to the seismic performance reference being the traditional cast-in-place building approach. Nonetheless, this study brings attention to several notable research gaps. These gaps include exploring innovative, resilient structural systems in greater detail and adopting state-of-the-art methodologies that facilitate decision-making processes in integrating PCB seismic safety and sustainability. This study provides a roadmap for future research projects and reports on the latest developments and trends in seismically safe PCB research.

Special Issue Information

Dear Colleagues,

This Special Issue is the 2nd edition of Trends in Sustainable Buildings and Infrastructure. The recently established Sustainable Development Goals call for a paradigm shift in the way buildings and infrastructures are conceived. The construction industry is a main source of environmental impacts, given its great material consumption and energy demands. It is also a major contributor to the economic growth of regions through the provision of useful infrastructure and generation of employment, among others. Conventional approaches underlying current building design practices fall short of covering the relevant environmental and social implications derived from inappropriate design, construction, and planning. The development of adequate sustainable design strategies is therefore becoming extremely relevant with regard to the achievement of the United Nations 2030 Agenda Goals for Sustainable Development.

This Special Issue aims to increase knowledge on sustainable design practices by highlighting the actual research trends that explore efficient ways to reduce the environmental consequences related to the construction industry while promoting social wellbeing and economic development. These objectives include but are not limited to:

  • Life-cycle-oriented building and infrastructure design;
  • Design optimization based on sustainable criteria;
  • Maintenance design towards sustainability;
  • Inclusion of social impacts in the design of buildings and infrastructures;
  • Resilience and sustainability;
  • Use of sustainable materials;
  • Decision-making processes that effectively integrate economic, environmental, and social aspects.

Papers selected for this Special Issue will be subject to a rigorous peer-review procedure with the aim of rapid and wide dissemination of research results, developments, and applications.

Submission
