Introduction
It is well understood from previous studies that once the floor span exceeds 6 m, serviceability limit state requirements, especially vibration behaviour, rather than strength limit state requirements tend to govern the design. This guide addresses the performance requirements of the floors to meet the strength and serviceability limit state design requirements and the focus is on design considerations for floor dynamics. The design process for the two floors is presented in two separate sections (Sections 3 and 4) but some of the steps and design criteria are common for both types.
These floor alternatives have been arrived at, based on industry input, to address key concerns when designing long-span timber floors: constructability and floor dynamics.
Recommendations on design criteria, procedure and parameters for vibration design are based on existing knowledge from literature and supported by extensive laboratory tests.
