Presented at 2025 International Workshop in Engineering Research Infrastructures for European Synergies (ERIES-IW2025), Lisbon, Portugal

This study investigates the feasibility of using Rubber-Soil mixtures (RSm) trenches as a Geotechnical Seismic Isolation (GSI) technology to mitigate earthquake-induced ground motions and enhance the resilience of existing structures. While previous... Read More about Geotechnical seismic isolation technology with rubber- soil trenches for earthquake resilience of existing structures.

An Innovative Approach to Geotechnical Seismic Isolation: Rubber-Soil Mixture Trenches (2024)
Presentation / Conference Contribution
Bernal-Sanchez, J., Mcdougall, J., Barreto, D., Dimitriadi, V., Leak, J., & Nseabasi, M. (2024, June). An Innovative Approach to Geotechnical Seismic Isolation: Rubber-Soil Mixture Trenches. Presented at 18th World Conference on Earthquake Engineering, Milan, Italy

This study presents a Geotechnical Seismic Isolation (GSI) system proposed for utilising Rubber-Soil mixtures (RSm) to enhance the dynamic performance of a modified soil and foundation structure. The inclusion of RSm enables the system to exhibit low... Read More about An Innovative Approach to Geotechnical Seismic Isolation: Rubber-Soil Mixture Trenches.

Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection (2022)
Presentation / Conference Contribution
Bernal-Sanchez, J., McDougall, J., Miranda-Manzanares, M., & Barreto, D. (2022, September). Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection. Presented at 3rd European Conference on Earthquake Engineering & Seismology, Bucharest, Romania

A Geotechnical Seismic Isolation (GSI) system is proposed in this study based on the use of Rubber-Soil mixtures (RSm) to facilitate the benefits of dynamic soil-foundation structure interaction. The latter is possible due to the lower stiffness and... Read More about Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection.

Housing Construction On Peatland: Phase 1 Report (2021)
Report
Bernal-Sanchez, J., McDougall, J., Medero, G., Cook, D., & Barreto, D. (2021). Housing Construction On Peatland: Phase 1 Report. Edinburgh: Construction Scotland Innovation Centre

The economic development and social resilience of communities in rural Scotland is being hampered by a shortage of affordable housing. Nationally, about 23,000 new homes per year are needed, whilst in the year up to October 2018, only 18,000 were bui... Read More about Housing Construction On Peatland: Phase 1 Report.

Numerical modeling of coupled biochemical and thermal behavior of municipal solid waste in landfills (2020)
Journal Article
Kumar, G., Reddy, K. R., & McDougall, J. (2020). Numerical modeling of coupled biochemical and thermal behavior of municipal solid waste in landfills. Computers and Geotechnics, 128, Article 103836. https://doi.org/10.1016/j.compgeo.2020.103836

A coupled bio-thermal (BT) model is proposed and validated for the prediction of long-term biochemical and thermal behavior of municipal solid waste (MSW) in landfills. The biochemical and thermal behavior of the waste was modeled using a two-stage a...

Grading entropy coordinates and criteria for evaluation of liquefaction potential (2019)
Presentation / Conference Contribution
Barreto Gonzalez, D., Leak, J., Dimitriadi, V., McDougall, J., Imre, E., & Lőrincz, J. (2019, June). Grading entropy coordinates and criteria for evaluation of liquefaction potential. Presented at 7th International Conference on Earthquake Geotechnical Engineering, Rome, Italy

Several methods are commonly used for the evaluation of liquefaction potential in soils. These include criteria based on SPT and CPT tests, shear wave velocity measurements and gradation limits, amongst others. This study applies the concept of gradi...

Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels (2019)
Presentation / Conference Contribution
Bernal-Sanchez, J., McDougall, J., Barreto, D., Marinelli, A., Dimitriadi, V., Anbazhagan, P., & Miranda, M. (2019, June). Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels. Presented at 7th International Conference on Geotechnical Earthquake Engineering, Rome

The dynamic properties of shredded rubber-soil mixtures (ShRm), comprising a sub-rounded quartz sand combined with small rubber shreds at 0, 10, 20, 30% by mass, were investigated. Testing ranged from small strain, in resonant column apparatus, to la... Read More about Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels.

Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms (2019)
Journal Article
Fonseca, J., Riaz, A., Bernal-Sanchez, J., Barreto Gonzalez, D., McDougall, J., Miranda Manzanares, M., Marinelli, A., & Dimitriadi, V. (2019). Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms. Géotechnique Letters, 9(4), 1-6. https://doi.org/10.1680/jgele.18.00221

Sand-rubber mixture (SRm) behaviour is affected by rubber content (RC) whilst dissipation in sands is caused by inter-particle sliding. Dissipation in SRm is as, or more significant than in sands. However, the mechanisms of dissipation in SRm are not... Read More about Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms.

Particle loss: An initial investigation into size effects and stress-dilatancy (2019)
Journal Article
