Rezumat
Lucrarea prezinta comportamentul imbinarilor in lemn cu tije metalice (buloane) sub sarcina permanenta, la solicitarea de tractiune. A fost realizat un stand de testare. S-au masurat deformatii ale imbinarilor
in functie de sarcina aplicata, durata de aplicare a acesteia, temperatura si umiditatea relativa a aerului din mediul
de testare, pentru fiecare imbinare in parte. Au fost utilizate tije cilindrice netede de diferite diametre. S-a realizat o comparatie intre deformatiile imbinarilor luate in studiu, pentru aceleasi conditii de mediu si solicitare.
De asemenea, s-a calculat viteza de deformatie a fiecarei imbinari in parte.

Abstract
This paper presents the behavior of wood joints with metal rods (bolts) under constant load, to traction
tests. A test stand was made. Deformations of bolted joints were measured according to the applied load,
duration of application, temperature and relative humidity of test environment for each joint separately. Were used smooth cylindrical rods of various diameters. A comparison between the deformations of the joints studied,
for the same environmental conditions and application was made. Also, the strain rate was calculated separately
each joint.
