Asset Management

Transport infrastructure condition monitoring and performance assessment, extending the life of structures.

Theme 4: Asset Management Research Projects

Project Title

Load paths and loading in existing buildings

Primary Theme

Asset Management

Secondary Themes

Sustainability and Urbanisation, Construction design and Technology

Project Summary

Dr Mike Cook, Chairman of Buro Happold, has stated that our industry is tearing down cities-worth of buildings instead of retrofitting them because we do not know how they are performing structurally. This is scandalous. It is essential that we understand the real loading in buildings prior to their retrofit and then, even more importantly, understand how these loads are transferred through the structure by means of measurement. It is impossible for anyone to know what the bending moment is at any point in a statically-indeterminate structure through prediction using standard structural analysis. Therefore, it is crucial that we develop easy-to-implement measurement protocols which allow us to determine the real load paths in buildings, together with real loadings, such that we have evidence-based knowledge to assist in decision making concerning retrofit possibilities. This project will conceive of, and develop, measurement protocols which will lead to the determination of real structural behaviour of existing buildings.

Construction Materials and waste minimisation, Sustainability and urbanisation

Project Summary

The UK spends over £50B/year, i.e. half of its construction budget, on the repair and maintenance of existing concrete assets. In the US the situation is worse and reportedly infrastructure asset owners owners pay ~$20B/year on concrete repair, protection and strengthening, with associated costs for maintenance due to steel corrosion alone reaching $125B/year. Compounding this issue is the fact that current repair systems are not effective. It is reported that in the EU 20% of concrete repairs fail within 5 years, 55% within 10 years and almost all within 25 years of service. There is hence significant potential and opportunities for innovation in the concrete repair area to hugely improve performance, reliability and permanence and reduce costs. There is wide range of commercial repair mortar systems for both structural and non-structural concrete including those for overlay and underlay applications, patch repairs, large volume repairs and dry spray applications, many of which are polymer modified Portland cement based systems.  The aim is to develop robust and resilient set of repair grout and mortar systems with a focus on surface treatments, e.g. overlays and coatings. The project will focus on a specific application (perhaps relating to both concrete and steel) and specific damage scenarios. It will include fundamental scientific developments, laboratory developmental and validation work and potential large scale field application.
