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.
Enhanced public safety and transformation of structural design for fire has resulted from improved building design through ERPE researchers' development of new and unique design methodologies, frameworks and tools for analysing fire spread. Fire safety engineering research within ERPE has created an improved scientific understanding of the effect of fire on structures and materials. Structural and fire safety engineers across UK, EU, USA, Canada as well as those who are members of international fire safety bodies have subsequently implemented significant advances for the design of safer, more economical, sustainable, and architecturally innovative buildings.
ERPE research has thus assisted the design and construction of increasingly optimised, sustainable, and economical buildings globally with significant changes in building design and regulation, particularly during 2009-2013.
The use of fire retardants is a requirement to reduce fire severity and deaths but is also controversial due to environmental (leaching) and health consequences of commonly used halogenated fire retardants. A novel methodology has been developed and validated in the Fire Safety Engineering Research and Technology centre (FireSERT), Built Environment Research Institute, for the prediction of large-scale burning behaviour of fire retarded polymers by combining small-scale (mg size) experiments with computer simulations of fire growth and toxicity. The research has been instrumental for companies in redesigning their products (fire doors and intumescent coatings) and is informing the development of EU regulations regarding the use and replacement of halogenated fire retardants. The research output has been published in leading journals, cited widely internationally and referenced by key organisations.
The Steady State Tube Furnace (ISO/FDIS 19700) allows fire toxicity to be quantified in real fire conditions. This has led to the introduction of "acidity classification" for cables in the European Construction Products Directive/Regulation (2008/2013) (as a surrogate for fire toxicity) to promote the use of safer, low smoke, zero halogen (LSZH) alternatives to PVC cables. Additionally, architects and building specifiers can use our data to avoid the most toxic foam insulation materials in low energy buildings. The biggest impact of our work, the global reduction in loss of life in fire is probably the most difficult to quantify, as too many other factors influence the fire statistics.
Our research provided the evidence to persuade companies to develop fire retardant formulations based on naturally occurring mixtures of hydromagnesite and huntite (HMH) that were more effective, cheaper, and greener than the market leader, aluminium hydroxide (ATH). Before the research started, in 2005, annual global sales of HMH as a fire retardant were less than [TEXT REMOVED FOR PUBLICATION] 000 tonnes. By 2012, sales had already doubled to [TEXT REMOVED FOR PUBLICATION] 000 tonnes (£[TEXT REMOVED FOR PUBLICATION] M) and continue to grow. LKAB minerals supply over 90% of the global market in HMH, and as a result of UCLan's fire retardant research, expect HMH to replace at least 25% of fine grade ATH within 5 years (increasing HMH sales to £[TEXT REMOVED FOR PUBLICATION] M). Not only is HMH a more effective fire retardant, it does not have the environmental problems associated with ATH.
Some of the most significant and widely used products for steel framed buildings in the global construction market today have been developed by the Structural & Geotechnical Engineering Research Centre at City University London. Our work in this field has permitted a saving of between 25 and 30% in the amount of steel needed for such buildings, making them now on average 9% cheaper than their concrete equivalents. Our research data from this work is now incorporated into at least six Design Guides and two significant industry software suites, published by the Steel Construction Institute (SCI) [text removed for publication]. Steel frame build times have been reduced by up to 13% and the resulting buildings can be 20-50% more energy efficient, helping the industry move towards its `Target Zero' carbon goals.
The dynamic response of steel members and floor systems has been a key concern in the industry over the last decade. The work undertaken at City has been effective in helping bring new products to market and in improving the application of structural mechanics to real design situations. It has also made a significant contribution to the increasing success of the steel industry in the UK commercial building market.
As academic lead partner Professor Ogden and his team at Oxford Brookes University were responsible for a major research programme focusing on the development of light steel construction technology. Major industry funding in conjunction with EU support, facilitated a detailed understanding of the technology, and various demonstration projects including the then largest light steel framed building in Europe, constructed at Oxford Brookes University. The results of the work have been adopted by industry in order to innovate novel construction solutions. As a consequence light steel framing is now the favoured method of construction across the entire modular off-site buildings sector and in other mass market construction applications including site-built structural framing and infill walling. The value of the market that that has emerged in the UK during the census period is estimated to be £78 million per annum.
University of Nottingham research into a composite design for steel beams and floor slabs has resulted in environmental and economic benefits and an important change in the construction industry. The work has reduced the weight of beams and the overall tonnage of buildings, enabled easier installation and improved structural strength. More than 40 projects, with a total combined floor area in excess of 380,000m2, have used the technology since 2008, and the method's market share has been estimated at up to 60%. The breakthrough has facilitated partnerships between steel frame designers and precast flooring manufacturers, with the value to the latter alone put at more than £5M.
The Fire Safety Engineering Groups (FSEG's) research related to fire dynamics, fire modelling, human behaviour and evacuation modelling is saving lives because it is used to design safer aircraft, ships and buildings. Its Economic impact stems from licensing the SMARTFIRE and EXODUS software to over 300 organisations in 32 countries and commercial applications of the software which enable the realisation of cutting-edge designs and enabling the continual safe use of heritage structures such as the Statue of Liberty. Impact on Practitioners is a result of changes to international maritime guidelines based in FSEG research and the wide scale use of the SMARTFIRE and EXODUS software by engineers around the world. Society impact results from its research featuring in a number of popular documentary programmes attracting audiences measured in the millions.
National and International design codes are the key vehicles for enabling structural engineering research to impact on practice. Recent years have seen substantial advancements in such codes for stainless steel structures, to which Imperial has made outstanding contributions [A-E]. Imperial research has led directly to improved structural design provisions, enabling more efficient structures, leading to cost savings [G], further promotion of the use of stainless steel in construction [A,H,I] and a reduction in the use of construction resources. The impact and reach of Imperial's research has not only been throughout the industry (producers [H], code writers [A] and practitioners [G,I]) but also global, with widespread influence on UK, European, North American and Asian practice [A].
