The University of Bristol’s civil engineering team has carried out a pioneering test by subjecting a 3D printed concrete house to a series of seismic simulations. This initiative, which seeks to understand how this type of structure responds to telluric movements, represents a crucial step in the validation of new construction techniques using additive manufacturing.
3D printing applied to seismically active structures
The BBC mentions that for the test, the researchers used the UK’s largest shaking tablecapable of replicating real earthquake conditions. The printed structure, fabricated by controlled deposition of concrete layers, was equipped with sensors to record its dynamic behavior under different levels of seismic intensity. levels of seismic intensity.
[post_relacionado]This type of construction incorporates new variables compared to traditional concrete: non-linear geometries, strength variations between layers and the absence of conventional forms. All this requires an exhaustive review of current structural safety standards, particularly in regions with relevant seismic activity.
Objective and data obtained from 3D printed concrete
During the test, progressive vibrations were applied, from mild to severe, monitoring the appearance of cracks, displacements and critical zones. The results will be used to compare the performance of the printed concrete with traditional methods, and to calibrate digital seismic prediction models.
Professor Anastasios Sextos and Dr. Raffaele De Risi, in charge of the project, explained that this study seeks to establish specific design parameters for 3D printing, such as the type of reinforcement and the bonding strategy between layers, with a view to achieving a safer, faster and more adaptable construction.
Impact on regulations and urban development
The research will provide useful data for engineers, architects and also for institutions in charge of formulating building regulations. The goal is to drive the responsible adoption of 3D printing technologies in urban contexts, particularly in social housing, emergency shelters and buildings in seismically vulnerable areas.
Through this seismic evaluation, the University of Bristol takes a firm step towards the consolidation of 3D printed concrete. 3D printed concrete as a viable and resilient alternative for the future of sustainable construction.
