DOL effect of different sized timber beams

The objective of an AIR PROJECT (1994-1997) was to establish a new scientific basis for the determination of the long term performance of reconstituted timber (glulam and LVL) in a variable environment with a duration of load of a few months. Three current problems of timber engineering were treated: delayed fracture in bending of straight or notched beams, delayed fracture of curved beams by tension perpendicular to grain, with the same methodology and with a sufficient number of tests to obtain a good statistical and phenomenological understanding of the phenomena.
