Rezumat

Lucrarea prezinta studiul principalelor imbinari din componenta unei structuri de acoperis. S-au masurat deformatii ale imbinarilor in functie de temperatura si umiditatea relativa a aerului din mediul de testare, pentru
fiecare imbinare in parte. S-a realizat o comparatie intre deformatiile imbinarilor luate in studiu, pentru aceleasi conditii climatice, in functie de tipul imbinarii, de incarcare si de pozitionarea in structura acoperisului. S-a realizat o comparatie a deformatiilor celor trei imbinari, pentru fiecare anotimp in parte.

Cuvinte cheie: structura de acoperis imbinari in lemn deformatii in timp temperatura umiditate relativa.

Abstract

This paper presents a study of principal wood joints from different parts of a roof structure. There were measured deformations of joints related to temperature and relative humidity of air from the testing environment, for
each joint separately. A comparison between joints deformations in study was made, for the same climatic conditions, related to joint type and loads and position in the roof structure. For each season, were compared deformations of the three studied joints.

Keywords: roof structure wood joints deformation in time temperature relative humidity
