Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection (2022)
Conference Proceeding
Bernal-Sanchez, J., McDougall, J., Miranda-Manzanares, M., & Barreto, D. (2022). Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection. In Proceedings of the 3rd European Conference on Earthquake Engineering & Seismology (2674-2683)

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)
Conference Proceeding
Barreto Gonzalez, D., Leak, J., Dimitriadi, V., McDougall, J., Imre, E., & Lőrincz, J. (2019). Grading entropy coordinates and criteria for evaluation of liquefaction potential. In Earthquake Geotechnical Engineering for Protection and Development of Environment and Constructions (1346-1353). https://doi.org/10.1201/9780429031274

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)
Conference Proceeding
Bernal-Sanchez, J., Mcdougall, J., Barreto, D., Marinelli, A., Dimitriadi, V., Anbazhagan, P., & Miranda, M. (2019). Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels. In Earthquake Geotechnical Engineering for Protection and Development of Environment and Constructions (1403-1410)

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., …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

Drained triaxial tests have been performed to explore the effect of particle loss on shearing behaviour and critical states in granular mixtures. The mixtures comprise Leighton Buzzard sand (d50 = 0.8 mm), to which was added 15% by mass of salt parti...

Dynamic behaviour of shredded rubber soil mixtures (2018)
Conference Proceeding
Bernal-Sanchez, J., McDougall, J., Barreto Gonzalez, D., Miranda, M., & Marinelli, A. (2018). Dynamic behaviour of shredded rubber soil mixtures. In Proceedings of the 16th European Conference in Earthquake Engineering

Residential buildings in high population density areas are seismically vulnerable to the action of major seismic events. The high cost and technical difficulties related to the use of advanced seismic isolations systems precludes its installation to...

Municipal solid waste (MSW) is biodegradable in landfills under anaerobic conditions. The evolution of the hydro-biochemical-mechanical (HBM) processes during degradation is investigated first through experiments and subsequently via modelling. Thr...
