already inspected with the use of hammer. A total of 4 tests were carried out with this apparatus, in the locations presented in Fig. 2 (a) along the floor beams. The results show that exists in some cases surface degradations and internal degradations of the wood. In Fig. 2 (b) is showed the example of a test in a beam. In the Fig. 3 to Fig. 6 are presented the resistograph graphics obtained for the 4 pavement beams tested.

The beam R1 results, next to the support, are presented in Fig. 3, being possible to verify that the beam is in food state of conservation and without apparent degradation, showing only a superficial degradation in the surface as it is possible to verify in the abscissa axis when the needle crossed the piece at 5 cm. It is also possible to see the total cross section dimension of the beam, in this case is around 33 cm.

Fig. 3. Obtained graphic of the R1 beam of the pavement, through resistograph (image from: [9]).

Fig. 4 show the graphic results for the beam R2, near the support delivery on the wall, displaying that this wood element was in poor state of preservation. It has a cross-section with constant deterioration, reaching the maximum resistance at approximately 6 cm of profundity. The deterioration in this beam should be associated with the high humidity content present, that lead to rotting. The beam cross section is about 24.5 cm.

Fig. 5 presents the graphic results obtained for the R3 beam next to the support delivery in the wall. As the R2 beam this one, by visual inspection was detected humidity, which is according to the results obtained in the resistograph that showed a degraded cross-section, probably due rotting. The maximum resistance occurs at approximately 5.5 cm probably due to existence of a knot. The cross section of the beam is about 25 cm.
