Abstract

The objective of the study was to evaluate, through visual classification and non-destructive tests, the state of conservation of 32 wooden beams for reuse as a restoration project for a historic building. For this, measurements of the moisture content, penetrometer, estimation of the modulus of elasticity and breaking stress by ultrasonic pulse velocity were made. The results showed that 66% of the beams were affected by rot, defibration and cracking. The tests carried out on the deteriorated beams made it possible to determine that, for a reliability of 95%, of the remaining 21 beams it was possible to reuse 17 of them with an average density of 0.4 g/cm3.
