| When assessing existing timber structures it is not possible to obtain density as the ratio mass/volume, so nondestructive probing methods are very useful tools to predict density. As in other nondestructive techniques, moisture content influences measurements. The goal of this paper is to study the influence of timber moisture content on two nondestructive probing techniques (penetration resistance and pullout resistance). 25 specimens of Scots pine (Pinus sylvestris L.) from Spain were tested. The moisture content ranged from 46.5% to 10.0%. Results obtained show that penetration depth decreases and screw withdrawal strength (pullout resistance) increases, when moisture content decreases, below the fiber saturation point. There are lineal tendencies in both techniques. Above the fiber saturation point influence of timber moisture content is much lower than below. Moisture content correction factors of the measurements, below fiber saturation point, are proposed for this species. | |
