Overview

Bed scour at bridges, and in particular scour at short span masonry arch bridges, has recently come to the fore due to an increase in the number of structural failures of, in particular, masonry arch bridges. The incidence of failure in short to medium span bridges within the UK and globally due to scour accounts for 70% of bridge collapses. While the problem of bridge scour is well documented, previous research in this area has concentrated on either the structural behaviour of arch bridges or the hydrodynamic interaction of the flow with the river bed. It is however, the consequential nature of the interaction between the bed scour and the structural response to this that causes collapse and is an area that has not been fully investigated. Additionally, there has been no research study of the FlexiArch bridge under pressurised flow where the lack of mortar could give different behaviour to traditional masonry arch bridges.

This research project aims to investigate the causes of scour in bridges using both numerical modelling and laboratory investigations. A scaled model masonry bridge will be built for the experimental analysis of the pier scour phenomenon as well as for its evaluation of the amount and shape of the differential settlement due to the pier scour by means of hydraulic tests. The monitoring will be coupled with a detailed nonlinear finite element simulation for a better interpretation of experimental results and to better understand the dynamic behaviour of the arch bridges. RESEARCH PROPOSAL Applicants should use the ‘Research Proposal’ section to provide a 500-word (maximum) discussion of the project description outlining: • Understanding of the proposed research question(s) aims and objectives • The broader context of the research and its relevance to engineering and science • A methodological approach to the work • Options for analysis of the data gathered

Funding Information

This research project is one of a number of projects at this institution. It is in competition for funding with one of these projects (SALine INtrusion in coastal Aquifers (SALINA): Hydrodynamic Assessment and Prediction of Dynamic Response). Usually the project which receives the best applicant will be awarded the funding. The successful candidate will be funded through a DfE 3-year studentship. To be eligible for a full award (stipend and fees), the candidate must have settled status in the UK (with no restrictions on how long they can stay) and been ‘ordinarily resident’ in the UK for 3 years prior to the start of the grant.

Research Profile

Full-time: 3 years

Civil Engineering overview

The research centre will address the topical grand challenges in the civil engineering field, building on existing and developing new international collaborations. Financial support to meet these challenges will be acquired through both internal University initiatives (for enhanced infrastructure and facilities) and external funding from government grants, charities and direct industrial support. Research will address the grand challenges of energy, carbon, clean water, infrastructure; exploring extremes and defining new limits. Key research areas include: Marine renewable energy Groundwater and environmental systems Geotechnics Intelligent infrastructure and high-performance structures Energy-efficient materials Mode of study/duration Registration is on a full-time or part-time basis, under the direction of a supervisory team appointed by the University. You will be expected to submit your thesis at the end of three years of full-time registration for PhD, or two years for MPhil (or part-time equivalent).

Course content

Associated Research The dynamic nature of this research has been key to our success in attracting significant funding from UK research councils, government departments and agencies. The Civil Engineering Research Centre (CERC) is a leading international, interdisciplinary centre that enables scientists and engineers from all areas of civil engineering investigation to work on diverse, yet complementary research. A special feature of the CERC is the extensive and diverse range of research topics being researched by students and staff in the Centre.

Introduction Many of our PhD graduates have moved into academic and research roles in Higher Education while others go on to play leading roles in educational practice, the public sector or within NGO’s. Queen's postgraduates reap exceptional benefits. Unique initiatives, such as Degree Plus and Researcher Plus bolster our commitment to employability. For further information on career opportunities at PhD level please contact the Faculty of Engineering and Physical Sciences Student Recruitment Team on askEPS@qub.ac.uk. Our advisors - in consultation with the School - will be happy to provide further information on your research area, possible career prospects and your research application.

Assessment processes for the research degree differ from taught degrees. Students will be expected to present drafts of their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually. This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year. The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.

Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.

Civil Engineering costs

There are no specific additional course costs associated with this programme.

Additional course costs

Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.

Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
