Geotechnical Consulting Group, GCG,  provides expert advice by applying the sciences of soil, rock mechanics and engineering geology to civil engineering design and construction, and to the preservation and enhancement of the environment.

StructureMode: a leading London-based firm of structural engineers at the cutting edge of novel, sustainable and innovative structural systems with unique expertise and experience in practice-based research and testing. They are world leaders in fabric formwork for casting reinforced concrete and lightweight tensile and tensegrity structures.

Projects

* The Engineered waste for sustainable and resilient land regeneration project is with McAuliffe. Waste is a significant challenge in major infrastructure projects. The ability to minimise and utilise waste will deliver significant cost savings and added value to projects. Waste streams relevant to infrastructure projects include both mineral (industrial by-products, mineral wastes, EC&D waste) and organic waste (e.g. biomass and plastics). Contaminated land is another challenging and complex waste stream. A significant number of  remediation projects currently involve some aspects of soil stabilisation and/or solidification processing with binder additions, which are also used for ground improvement applications.

The project will map and prioritise several waste streams and explore their potential in the development of a range of smart, cost-effective and sustainable binders for use in land remediation and regeneration. The project will build on the significant advances made as part of the TSB project SMiRT (Soil Mix Remediation Technology). The project deliverables will contribute to national and global decarbonisation and circular economy strategies as well as the UN Sustainable Development Goals. For general enquiries, please email cdtcivil-courseadmin@eng.cam.ac.uk. For project-specific enquiries please e-mail Professor Abir Al-Tabbaa at aa22@cam.ac.uk. The closing date for this application is 31st January 2021. Please apply for the studentship at www.jobs.cam.ac.uk/job/27729/  

* The Mechanical Behaviour of Artificially Frozen Ground: Experimental Observations and Modelling project is with GCG The applications of artificial ground freezing in construction cover the formation of frozen earth walls to support deep excavations, structural underpinning for foundation improvement, and temporary control of ground water. The growing awareness of the merits of artificial ground freezing as a temporary ground improvement system with minimal environmental impact is directly related to progress in the understanding of the mechanical behaviour of frozen soils. However, a solid framework has yet to be established for the fully coupled thermo-hydromechanical behaviour of frozen/unfrozen soil and there is need for fundamental research to be carried out on experimental characterisation and constitutive modelling.

The proposed project will develop, set-up and use innovative laboratory equipment to investigate experimentally the behaviour of soil on freezing and thawing. The project will provide valuable insight into the mechanical behaviour of frozen soils, drawing upon multi-disciplinary knowledge at the interface between soil mechanics, thermodynamics, soil physics, material science, and industry. For general enquiries, please email cdtcivil-courseadmin@eng.cam.ac.uk. For project-specific enquiries please e-mail Professor Giulia Viggiani [gv278@cam.ac.uk] The closing date for this application is 30 June 2021. Please apply for the studentship at www.jobs.cam.ac.uk/job/27884/

* The New one-dimensional models and application to the design of reconfigurable pop-up structures project is with StructureMode. The climate emergency triggers the development of novel systems that optimize structural performance while minimizing material and manufacturing costs. Reconfigurable structures are particularly interesting as they are manufactured off-site and offer the possibility of adaptive designs for multi-purpose applications. We focus on tape-springs which are promising candidates for the design of reconfigurable structures as they undergo a complete change of shape upon folding. They can be coiled onto a spool, which allows the length of the members to be adjusted. Designing a structure made of tape-springs is a challenge. It is classically achieved via computationally expensive finite element simulations, which makes the exploration of the design space intractable.

We will develop a 1-dimensional (1-d) model starting from a nonlinear shell theory by dimension reduction. By contrast to existing approaches based on approximate kinematics, we will use an asymptotic method and hence ensure the accuracy of the final 1-d theory. This will involve solving a series of boundary value problems on a cross-section. We will work on an efficient numerical method to achieve these computations and on its integration in a user-friendly numerical framework. We will use this new modelling tool to design a reconfigurable structure made of tape-springs. This step will include addressing practical challenges raised by the design, such as investigating end effects, assessing the overall stability of the structure and predicting its load capacity and buckling mechanism.

This project will result in an efficient and accurate modelling tool for thin reconfigurable shell structures and thus improve the understanding of the nonlinear behaviour of these systems. Investigating proof-of-concept practical solutions for junctions and deployment mechanisms will also be an important step towards integrating these structures quickly into real world structural applications.

For project-specific enquiries please e-mail Dr Claire Lestringant [casl4@cam.ac.uk]. The closing date for this application is 31 January 2021. Please apply for the studentship at www.jobs.cam.ac.uk/job/27909/  and at the StructureMode page www.structuremode.com/projects/resilience-in-a-changing-world-fibe2-cdt/
