Integrating Structure, Systems, and Space: CLT + Steel

Abstract

This thesis examines building system integration for Cross-Laminated Timber (CLT), an emerging engineered wood building product. CLT is structurally robust, constructionally efficient, and environmentally friendly, but the fledgeling product remains under-utilized, and its full potential has not been realised. As a versatile and highly advantageous alternative to conventional structural systems, newly engineered wood products such as CLT could leapfrog concrete and steel structural systems. Despite its benefits having a vast amount of documentation, the development and exploration of CLT as part of a fully integrated building system have been limited. The study of critical junctures ranging from the scale of the detail to the size of the building will investigate opportunities to realise the benefits of CLT entirely. This thesis proposes a multi-functioning steel system to complement and complete CLT. A series of steel seams integrate both the structural connections and building services simultaneously. The multi-functioning steel components will further develop how connections and systems can be woven together to create a clean, minimal architectural expression. Ultimately, the steel system will highlight and expose the full functionality and beauty of CLT, while making an undressed wood building.
