PhD Study : ​Structures Fire Behaviour and Protections Fire Performance

Apply and key information  

Summary

​The principal thrust is the experimental evaluation of the structural behaviour in fire of a variety of materials and structural assemblies. The focus is on the principal building materials i.e. steel, concrete, brickwork, timber, fiber reinforced plastic “FRP”, flooring systems, facades glazing panel systems and compartmentation. The second thrust is the study of the correlation between thermo-structural response and the quantification of thermal onslaught and transmission, seeking definitions of fire severity on structures. Fire testing studies examined furnace severity in both the large-scale and indicative furnaces at FireSERT, complying with European Standards, enable direct correlation to end user needs.

In examining the behaviour of structural assemblies in fire, the principal objective of FireSERT’s research is to use experimental parametric studies to provide comprehensive scale model test data. This informs design guidance within a limit state philosophy (parametric experimental data linked to computer simulations forming the basis of statistical and sensitivity analyses). For cost effective research FireSERT also have several small purposes designed furnaces for this research work.

The Structural Fire Engineering Current Principal Research Programmes Focus On:

1-Modular Building System Fire Performance

2- Precast concrete sandwich panel walls Fire Resistance

3- Behaviour of Glazing Façade Panel System in Tall Buildings

4-Experimental and Numerical study on Fire Performance Steel Joints

5-Experimental and Analysis of spread/travelling interacting steel structures.

6-Fire resistance of Ultra high strength concrete columns, beams and slabs

7-Fire behaviour of composite flooring/offshore platform systems and protections

8-Earthquake and fire in buildings

9- Tunnels and transportation vehicles fire impact

10- Coupling method for FEA and CFD modelling of structure behaviour in fire

​FireSERT has state of the art research facilities which are virtually unique within a university setting. These include a 600m2 burn hall which houses a range of calorimeters including a ten-megawatt facility for full-scale research. Large-scale combination wall and floor furnaces together with intermediate/small scale furnaces facilitate experimental research and product development.

Equipment to be used in this project is listed as: crane, data logging systems, thermocouples, LVDTS, large furnace, load cells, hydraulic loading equipment, dynamic loading equipment. Concrete lab including using concrete mixers, vibrating table, curing tanks.

FireSERT has collaborated with a number of national and international organisations and is currently involved in deferent projects linked with European, industrial and building control partners in the sustainability and resilient buildings.  FireSERT's unique data was used by British Steel to press the UK case regarding the plate thermometer in European harmonisation debates. FireSERT possess the only heat flux-time curves for the Cardington LBTF full scale compartment fire tests and the NFSC2 compartment tests and recently conducted large scale fire compartment for long cellular beams with a recent development of new Eurocode. The research student will have opportunities to attend meet with experts in his research area and also to collaborate with other leading groups in the School Built Environment.

Essential criteria

Applicants should hold, or expect to obtain, a First or Upper Second Class Honours Degree in a subject relevant to the proposed area of study.

We may also consider applications from those who hold equivalent qualifications, for example, a Lower Second Class Honours Degree plus a Master’s Degree with Distinction.

In exceptional circumstances, the University may consider a portfolio of evidence from applicants who have appropriate professional experience which is equivalent to the learning outcomes of an Honours degree in lieu of academic qualifications.

  • Clearly defined research proposal detailing background, research questions, aims and methodology

Funding and eligibility

The University offers the following levels of support:

Vice Chancellors Research Studentship (VCRS)

The following scholarship options are available to applicants worldwide:

  • Full Award: (full-time tuition fees + £19,000 (tbc))
  • Part Award: (full-time tuition fees + £9,500)
  • Fees Only Award: (full-time tuition fees)

These scholarships will cover full-time PhD tuition fees for three years (subject to satisfactory academic performance) and will provide a £900 per annum research training support grant (RTSG) to help support the PhD researcher.

Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year (or part-time equivalent) are NOT eligible to apply for an award.

Please note: you will automatically be entered into the competition for the Full Award, unless you state otherwise in your application.

Department for the Economy (DFE)

The scholarship will cover tuition fees at the Home rate and a maintenance allowance of £19,000 (tbc) per annum for three years (subject to satisfactory academic performance).

This scholarship also comes with £900 per annum for three years as a research training support grant (RTSG) allocation to help support the PhD researcher.

  • Candidates with pre-settled or settled status under the EU Settlement Scheme, who also satisfy a three year residency requirement in the UK prior to the start of the course for which a Studentship is held MAY receive a Studentship covering fees and maintenance.
  • Republic of Ireland (ROI) nationals who satisfy three years’ residency in the UK prior to the start of the course MAY receive a Studentship covering fees and maintenance (ROI nationals don’t need to have pre-settled or settled status under the EU Settlement Scheme to qualify).
  • Other non-ROI EU applicants are ‘International’ are not eligible for this source of funding.
  • Applicants who already hold a doctoral degree or who have been registered on a programme of research leading to the award of a doctoral degree on a full-time basis for more than one year (or part-time equivalent) are NOT eligible to apply for an award.

Due consideration should be given to financing your studies. Further information on cost of living
