Descripción del proyecto
Métodos de construcción modernos para unas estructuras más seguras y sostenibles
Los métodos de construcción modernos son muy precisos, mejoran la seguridad y reducen los residuos gracias a unos procesos optimizados de fabricación y construcción. Sin embargo, la falta de directrices sobre la interacción entre los componentes estructurales y el comportamiento del sistema de conexión dificulta su uso en todo el mundo. La construcción con paneles de carga de acero conformado en frío es un método de construcción moderno que presenta varias ventajas en comparación con las técnicas de construcción estándares. Sin embargo, se sabe poco sobre la robustez de dichas estructuras porque escasean datos sobre ensayos y modelización. El proyecto ConCatenaTion, financiado con fondos europeos, desarrollará unos nuevos prototipos de conexión, orientación para el diseño e idealizaciones que deberían facilitar el diseño robusto de estructuras de paneles de acero conformado en frío contra el colapso desproporcionado, a la vez que utiliza la acción catenaria ventajosa como mecanismo de resistencia al colapso.
Objetivo
Modern methods of construction (MMC), which are highly precise, improve safety and reduce waste due to their streamlined manufacturing and construction processes, are essential to address global deficits in residential accommodation supply, reduce homelessness and housing cost overburden, whilst targeting UN sustainable development goals 11 and 13 (sustainable cities and communities and climate action, respectively). Despite its benefits, MMC use is limited worldwide, with the lack of knowledge/guidelines on the interaction between structural components and connection system behaviour playing a major role.
Built offsite, cold-formed steel (CFS) load-bearing panelised construction is a MMC that offers additional advantages over standard construction such as high recyclability, ease of construction and reduced structural weight, which all combine to reduce construction-related carbon emissions. However, little understanding exists on the robustness of such structures, exacerbated by lack of published testing and modelling data.
This fellowship aims to develop a novel connection prototype to enable the utilisation of catenary action within the disproportionate collapse resistance mechanism in CSF MMC. This research will, for the first time, provide much-needed design guidance and structural idealisations for use in global structural models necessary for the robust design of CFS panelised structures against disproportionate collapse.
Project aims will be achieved through 1) small and medium-scale structural testing, and 2) replication of structural behaviour using advanced numerical analysis to progress a comprehensive understanding of the complex interaction between components, enabling the development of new connection design criteria that includes catenary action. The project findings will be disseminated without prejudice (typically this is not the case in the field), leading to safer and more sustainable structures and higher uptake of CFS MMC in the industry.
