We have developed the Bailey-Method, design software FIRESOFT and a web-based information source for designers to use to produce safe and economical buildings. In buildings that have used the Bailey-Method, approximately 40% of the fire protection cost has been saved. The overall saving is about £20m in the UK over the REF period. The Bailey-Method has been presented in 2500 design guides (books), distributed to companies across Europe by ArcelorMittal, and translated into 17 languages. FIRESOFT and the associated quality assurance document enable using unprotected concrete filled tubular columns and have the British Standard status of Non Contradictory Complementary Information.
The traditional "deemed-to-satisfy" method for specifying fire protection to steel-framed buildings is based on controlling the increase in temperature of the steel structure and ignoring the actual structural behaviour of the building during a fire. Our research focuses the performance-based fire engineering design methods for steel-framed structures. This was developed on the full understanding of the fundamental behaviour in fire of all the main structural components and building in its entirety, allowing the development of economical and safe design methods.
Development of the theory, and design method, for tensile membrane action (TMA) in composite slab steel beam floor systems at elevated temperatures [1, 2]. TMA is a load-carrying mechanism mobilised at very large deflections that enables the floor to develop a load carrying capacity much higher than the capacity that is normally used in structural design. Utilising TMA exploits the inherent reserve in strength of the floor, enabling the floor to sustain the applied loads in fire without the need for additional fire protection for up to 40% of the steel floor beams. Our research has formed the basis of the new fire engineering design method for multi-storey steel framed buildings  that is often referred to as the Bailey-Method in the steel and fire protection industry.
We have proposed and validated an alternative fire resistant design method for concrete filled steel tubular columns within buildings .
Quantification of connection behaviour and their importance to robustness of steel-framed structures in fire . Connections in steel-framed structures are critical to ensuring structural survival in fire, but connections are rarely explicitly considered in the fire resistant design of steel structures.
Our research is published in the most prestigious academic and professional journals in the fields of structural engineering and fire science. Publication  won one of the two Henry Adams diplomas for the best research paper published in The Structural Engineer in 2010.

Fire resistance is one of the most important safety requirements in buildings and is covered by legislation. Until recently, designing for structural safety in fire was predominately based on simple "deemed-to-satisfy" prescriptive methods presented in supporting documents to the UK Regulations. Following such prescriptive rules adds 20 to 40% unnecessary fire protection cost to steel-framed buildings. Since the majority (over 70%) of multi-storey buildings in the UK are constructed using steel-framed structures the unnecessary cost in terms of materials and labour is significant within the built environment.
Our experimental and theoretical research, leading to the Bailey-Method, enabled the construction industry to finally address the use of unnecessary protection costs ensuring that protection to the structure is only applied to areas where it is needed. In addition, our research has led to a further design method for concrete filled tubular sections, where protection is safely eliminated altogether.
Our research has been presented at leading conferences, at professional seminars, dedicated CPD courses and published in leading journals. We have developed practical design guides and software to promote the methods based on our research.
We developed the One-Stop-Shop dedicated web-site to Structural Fire Engineering (www.mace.manchester.ac.uk/project/research/structures/strucfire/) to promote performance-based methods to practical designers. This website was developed by Manchester with contributions from DTi (now TSB), TATA Steel, The Concrete Centre, Pilkington, Arup, and Buro-Happold. It offers authoritative and impartial advice together with training materials, attracting over 590,000 visitors within the REF period.
i) ArcelorMittal has presented the Bailey-Method in a number of design guides with 2500 copies distributed to companies in over 20 countries and incorporated it into their MACS+ design software which is available in 17 languages. The method was deployed in: the: BOBST building (Switzerland, 2010); ArcelorMittal Steel Centre (Belgium, 2008); EVS Building (Belgium, 2008); Geric Commercial Centre in France (2013); and the BNP Bank Tower in France (2013) [A].
Other companies have used the Bailey-Method on projects between 2008 and 2013 including West Cheshire College Ellesmere Port (2008) saving £35k, Aquinas College Stockport (2008) saving £40k, and Derby Riverlights (2009) saving £65k [B].
