Abstract

The introduction of engineered beams offered longer span, lower cost joists in comparison to traditional solid timber sections; however, vibration criteria in the design codes may significantly reduce the permissible span of joists for domestic construction. This research is concerned with the structural performance of engineered, multi-webbed, composite, timber joists of double I, box and box-I, cross sections in comparison with commonly used I beams and solid timber joists for use as repetitive members of flooring systems. The paper details results and findings of a series of experiments designed to ascertain the dynamic performance of empty and polyurethane-filled, multi-webbed, composite, timber beams
