Innovations in Assessing Fire Resistance: Collapse Mechanisms of Steel Structures

Summary

The fire resistance of structures is a crucial element in modern engineering and plays a significant role in our built environment. While various materials are utilized in construction, structural steel elements are preferred for key structures such as tall buildings, parking facilities, and contemporary open floor plans. Additionally, cold-formed steel (CFS) is a common construction method for low-rise industrial buildings (typically 1 to 2 stories) and temporary residential structures.

Currently, the assessment of fire resistance in steel members relies on standard fire tests conducted on individual components. This method is valued for its convenience and simplicity. Previous fire tests and documented fire incidents have demonstrated that steel members exhibit enhanced fire resistance under service conditions. This is attributed to variations in fire exposure, the transient heating of the structure, and the interaction with surrounding structural elements that influence load distribution.

The proposed PhD project aims to explore the collapse mechanisms of steel structures during fire incidents. It will include comparative analyses of the responses of structural elements exposed to fire scenarios, both as standalone components and as part of the overall structural framework. During the computational modelling phase, data from various fire tests will be employed to validate analytical methods and conduct parametric studies. Insights gained from this research will emphasize the differences in the behaviour of structural members when analysed individually versus as part of the structural frame. The findings will contribute to the development of realistic fire response designs and advance performance-based design approaches in fire safety. Ultimately, the results of this study will have a global impact on the design, manufacturing, and construction industries, aiding in the protection of lives and property during fire emergencies.

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.

• Research proposal of 2000 words detailing aims, objectives, milestones and methodology of the project

Equal Opportunities

The University is an equal opportunities employer and welcomes applicants from all sections of the community, particularly from those with disabilities.

Appointment will be made on merit.

Funding and eligibility

This project is funded by:

• Department for the Economy (DfE)
• Vice Chancellor's Research Scholarship (VCRS)

Our fully funded PhD scholarships will cover tuition fees and provide a maintenance allowance of £19,237 (tbc) per annum for three years* (subject to satisfactory academic performance).  A Research Training Support Grant (RTSG) of £900 per annum is also available.

These scholarships, funded via the Department for the Economy (DfE) and the Vice Chancellor’s Research Scholarships (VCRS), are open to applicants worldwide, regardless of residency or domicile.

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.

*Part time PhD scholarships may be available, based on 0.5 of the full time rate, and will require a six year registration period (individual project advertisements will note where part time options apply).

Due consideration should be given to financing your studies.
