The impact of demountable connections on effective use of materials in timber structures
Abstract
<p>The construction industry is responsible for much global carbon emissions and resource depletion. As it moves towards a circular economy, the use of demountable timber connections could reduce material waste and improve efficiency. This paper looks at how these connections affect the use of materials in timber structures. It compares traditional fixed connections with various market-available and demountable ones, and how this affects material consumption, performance and reusability.</p><p>A combination of theoretical calculations, finite element modelling and case study analysis was used to assess the viability of these connections. Results show that demountable connections can significantly reduce material use without impacting structural integrity. They also facilitate ease of disassembly and extend the lifecycle of components. However, challenges remain, including standardisation, long-term durability, and the need for further research on the behaviour of connections over multiple use cycles.</p>
