  This research will be conducted in collaboration with James Jones and Sons. The aim is to conduct a research investigation to evaluate the influence of geometrical and numerical configurations of web openings on the strength and stiffness of I-joists. The other purpose is to develop design approaches that can assess satisfactory ultimate and serviceability performance of I-joists with web openings. This research will provide a deep understanding of the presence of web openings and their effects on the strength and stiffness of I-joists. The outcome from this work will provide general guidelines for facilitating web holes during construction phase. This study could be a valuable contribution in timber structures, especially for industry and for design codes.
