| Popis: | This paper presents results of a research programme investigating the mechanical properties of self-tapping screws and nails in wood. The programme consisted of deformation-controlled tests to determine embedment strength, withdrawal strength, pull-through strength, bending capacity of individual screws, shear strength of screwed and nailed woodwood connections, and shear strength of screwed woodsteel connections. All test specimens showed ductile behaviour. Based on the results from the first four types of tests, a simple calculation model for the shear strength of screwed woodwood and woodsteel connections was set up and compared with test results from the last two types of tests. The calculation model took dowel action and friction (woodwood and woodsteel) into account and showed excellent agreement with the test results.Key words: connections, screws, nails, shear strength, embedment strength, withdrawal strength, pull-through strength. |
