There are substantial commercial pressures driving the current trend in reinforced concrete multi-storey structures towards longer spans and thinner structural depths. The potential benefits of clear open spaces, the freedom of placing services and the reduction of building height (and the subsequent potential reduction in cladding costs) or conversely, the ability to incorporate an extra floor in the building (thus increasing rental potential) can have a significant effect on the overall economics of a scheme. However, these benefits cannot be fully exploited until it is possible to predict accurately the long-term deflection of concrete elements.A major problem in predicting the long-term deflection of cracked concrete flexural elements has always been the difficulty in isolating the deformation due to shrinkage from the effect of other parameters such as creep and tension stiffening. Current codes predict the long-term deflection of cracked concrete elements by using the approach developed for uncracked sections but incorporating cracked section properties. Whilst there is no question of the correctness of this in relation to uncracked sections, it has never been experimentally validated for cracked sections. Consequently, it may be extremely conservative and, therefore, have a restrictive influence on design strategy. The effect of shrinkage on a cracked section remains uncertain as it has not been possible to confirm the influence experimentally. The applicants now believe it is possible to overcome this difficulty and this application proposes an extremely innovative experimental approach which will allow the effect of shrinkage on the deformation of cracked members to be isolated for the first time. Recently, research by the applicants under a previous EPSRC funded project has resulted in a much better understanding of the tension stiffening phenomenon and, in particular, its decay with time. The effects of creep are already generally well understood. The results of the proposed research, and the data obtained by the Leeds and Durham concrete research team on tension stiffening, will finally allow designers to predict the long-term deflection of cracked concrete flexural elements with greater reliability.The current climate within the construction industry and the effect this has had on the cost and availability of steel is leading, and will continue to lead, to an increased use of concrete in construction (e.g. the major new Clarence Docks development in Leeds, where previously steel would have been chosen). The research is, therefore, very timely. It is now even more critical that this information is available to designers to ensure that maximum efficiency in the design and use of concrete is achieved so as not to restrict their competitiveness within the UK and EU construction industry.The proposed research will be performed at both the University of Leeds and the University of Durham. The experimental programme consists of two stages. The initial stage is concerned with confirmation of methodology. The second stage will isolate the effect of shrinkage using the innovative approach proposed by the investigators, contributing to an improved design method and more accurate assessment of shrinkage. The proposal has 6 industrial collaborators providing in-kind and cash contributions totalling 33,460. The total amount of funding being sought by the two universities is 274,537.

The I'DGO Research Consortium has a continuing overall aim to identify the most effective ways of ensuring that the outdoor environment is designed inclusively and with sensitivity to the needs and desires of older people, to improve their quality of life. In focusing on the changing needs of older people, the Consortium will address issues that are relevant to a much wider range of people in society as a whole, including disabled people, frail or vulnerable people and those who care for them. The proposed research under I'DGO TOO combines the skills and experience of three research centres and academic colleagues across five academic institutions. It brings this expertise together with that of a range of collaborators from different organisations, agencies and groups, ranging from ODPM to Age Concern, who are keen to use the findings of the research and benefit from it,I'DGO TOO focuses on particular policies and strategies that are currently being promoted by government as part of the sustainability agenda / urban renaissance, integrated communities and inclusive environments / where the potentially important, practical implications for older people's lives have not fully been explored and tested. It investigates how well outdoor environments in certain types of development, built in line with these policies, contribute to older people's health and wellbeing. It does so through research at three different levels of detail. It explores the implications of denser urban living on open space in housing, pedestrian-friendly approaches (such as Home Zones) in street environments and the practical consequences of using tactile paving in the urban environment. A range of innovative methods, some of which have been developed in earlier research by the consortium, will be used to examine in detail how design, and older people's perceptions of the designed environment, make a difference. The voices of older people themselves are a key element in this research. I'DGO TOO recognises the great diversity and range of abilities, disabilities, aspirations, expectations and needs that are encompassed in the population of people over 65 years of age. From the beginning, older people will be involved in expressing what is important to them and in shaping the development of the programme. The approaches used treat older people and disabled people as co-researchers, rather than 'subjects', and the range of techniques place these people at the heart of the investigation. A number of different methods is used to ensure that diverse perspectives and evidence is collected to throw light on the questions and objectives of the research. The main issues to be addressed are: how residential outdoor space in higher-density 'urban renaissance' housing can best be delivered to optimise older residents' quality of life; whether Home Zones provide a good design solution in the context of an ageing population, and the implications of the design, siting, laying and use of tactile paving for older people?The implications of the findings will be important for policy-makers, planners, designers and other professionals working in the urban environment, as well as users of that environment. The research collaborators will help ensure that the outputs are useful and useable for the range of people and groups for whom this work is important. Guidance will be published in a range of formats and media, including attractive and accessible printed booklets as well as web-based publications targeted to suit the needs of different expert, academic, professional and lay audiences.
