About the Project

With the increase in the open plan floor areas, the travelling fires are getting more common and have recently been documented during the fire events including the World Trade centre fire, the Windsor Tower fire, the Faculty of Architecture Building Delft University of Technology Fire and more. An understanding of the travelling fires and their impact on the structural elements is essential considering the modern day open floor construction. FireSERT has recently completed a series of travelling fire tests aiming at understanding different stages of the travelling fires including the development stage, the travelling stage, the steady stage and the decay state. The learnings and results from these experimental investigations have been published in recent publications listed in the references.

The proposed PhD project will investigate the response of structural elements in travelling fires through computational investigations. The data from the travelling fire tests, published through the research articles and conference contributions by Ulster University and elsewhere will be used to validate the computational models and parametric and sensitivity studies will be conducted to investigate the influence of different parameters. Data from the computational studies will be used to identify the lack of the current design codes and improvements will be devised for future use to safeguard lives and properties in case of fire events. The concept of travelling fires being a recent development, the findings from the study will benefit the design, manufacturing and construction industries on a global scale.
