Advancements in Timber Construction: A Review of Prefabricated Mass Timber Floor Assemblies

Abstract

This paper provides a state-of-the-art review of prefabricated mass timber floors, with a focus on composite floor assemblies for common residential and long-span office applications. The discussion relates to different design aspects, including connection systems and methods of assembly. Also, design methods and code provisions for the floor assemblies comprising ultimate limit state design, vibration control and long-term behaviour are expounded. A life-cycle overview of floor solutions is also presented to highlight their sustainability potential. The paper demonstrates how the building industry can leverage the structural performance, light weight and prefabrication capabilities of these innovative floor solutions for a better-built environment.
