Research on strength characteristics of the wooden end joints used in the buildings

In this study, tensile and stretching strength of three types of wood (yellow fir, chestnut, abies) which are used in the connections with rowshare end joints, flat rowshare, hidden rowshare and chamfered rowshare groove at a certain level of moisture u= 12 % is examined and a group of experiments are carried out. The samples are assembled with each other through polivinilasetat (PVA) glue. 'The experiments indicate the following results: Lit is observed that yellow fir was the most resistance material as a result of the tensile and stretching test made on these three types of wood with different characteristics. 2. It is observed during the test that the best jointing method in terms of tensile strength is the hidden rowshare with grooves and there is no difference among the jointing methods in terms of their stretching strength.
