This report describes a program plan required to develop dynamic performance criteria for the design of wood-based floors in commercial occupancies. The need for serviceability criteria for wood joist floor systems in residential settings had long been recognized. This recognition led to the adoption of new span tables for Part 9 of the 1990 National Building Code which indirectly limited vibration amplitude and frequency (NBCC 1990) based on the research conducted and the Eastern Laboratory of the Canadian Forestry Service (now Forintek Canada Corp.). The introduction of these additional criteria into Part 9 of the NBCC to limit dynamic effects was the beginning of a true systems approach to floor design. It is now in the best interest of the wood industry to extend the systems approach to the design of wood-based floors in commercial occupancies, where the floors are likely to use engineered type wood products rather than solid sawn lumber, and combined with concrete toppings of various types. No dynamic performance criteria can be applied to these applications, in part because the basic work required to instill confidence in any proposed criteria has not been done. Dynamic performance criteria are now needed to serve the interest of the wood industry and to provide reliable guidance to the design professionals.
