dc.description.abstractSteel is a highly versatile and 100% recyclable material but is also carbon and energy intensive in production. Steel framed structures are inherently adaptable and potentially demountable. Reuse instead of the common practice of recycling steel by melting, makes good environmental sense, saving both on resources and carbon emissions. Reuse is commercially and technically viable, as demonstrated by isolated projects. Although steel reuse has been identified as an effective method to reduce the carbon and energy impact of construction, it is in effect only marginally used in practice. We found that although there is a sufficient spread between the price of steel scrap and new steel, this difference cannot be captured by the demolition contractors. In steel multi-storey high-rise building structures, composite construction is the most efficient and economic forms of construction. Composite beams incorporate composite floors with profiled steel sheeting are the most common structural system used in multi-storey high-rise buildings and is seen as one of the most important ways of expanding the use of steel buildings in Europe, i.e. increasing market share. However, in terms of reuse, current composite construction systems require extensive cutting on-site during the demolition process making reuse not viable. This paper presents an innovative composite system that is designed for deconstruction and reuse, its structural behaviour and failure modes were observed and analysed through a series of experimental studies and numerical simulation. The results showed that the structural behaviour of this new form of composite system not only allows for deconstruction and reuse, it has a similar structural performance to the traditional composite system with welded shear connectors.en_US
