| Özet |
| In this study, the bending moment capacities under the diagonal compression and tensile loadings of the mitre frame corner joints with dovetail fittings were investigated. Solid poplar wood (Populus nigra) was used in the production of framework pieces. Recently, mitre frame corner joints with dovetail fitting are preferred in practice. This has been influential in the making of this study. A total of 80 each mitre frame corner joint specimens with dovetail fitting were prepared for this purpose. Of these, 20 were prepared with polyvinyl acetate (PVAC) adhesive, 20 were prepared with polyurethane (PU) adhesive, 20 were prepared with cyanoacrylate (CA) adhesive and 20 were prepared without adhesive (WA). Solid poplar wood (Populus nigra) was used as a frame material. The specimens were subjected to diagonal tensile and compression processes in the universal test machine in accordance with ASTM-D 143-94. The data obtained at the end of the tests were analyzed statistically and the results were evaluated. According to this, the highest bending moment capacity und er the diagonal compression loading (MC-L)(55.71 N· m) and bending moment capacity under the diagonal tensile loading (MC-T)(160.55 N· m) was obtained in the specimens bonded with PVAC adhesive. Whereas, the lowest MC-L (18.45 N· m) and MC-T (14.06 N· m) was obtained in the specimens without adhesive (WA). The difference between the MC-T and the MC-Cof the specimens bonded with the CA and PU adhesives was insignificant. Accordingly, it is definitely necessary to use adhesives in the bonding of dovetail fittings for obtaining a higher MC-T and MC-C. The … |
