    The potential of nailed all timber box beams
    (2011) Hettiarachchi, MTP; Welhena, KM; Chandraratna, PG; Priyadharshana, KHPV
    The potential of combining small dimension timber with timber webs of suitable thickness has been demonstrated by of this experimental investigation on nailed built up timber box beams of different cross sectional profiles in which the flanges and webs are entirely of timber. No literature was available on such timber box beam construction. The effect of web thickness, overall depth, and shape of flange on the load carrying capacity and flexural rigidity of timber box beams were investigated. Timber beams consisting of webs of 25 mm thickness and overall depth of 225 mm were shown to be the most cost effective. The profile of the flange does not appear to have a significant effect on either the load carrying capacity or flexural rigidity. No attempt wa
