Özet

Since staple is the most used fastener in furniture frame, its holding capacity in solid wood joints is need to be known. Therefore, lateral shear resistance capacity of one stapled and one-row multi stapled joints constnicted from Scotch pine, alder, and beech Were investigated. Results showed that the joints constructed from beech with a density of 540 kg/m(3) yielded 4893 N, the 4 staples joints constructed from alder with a density of 510 kg/m(3) yielded 4487 N. and the 4 staples joints constructed from Scotch pine with a density of 450 kg/m3 yielded 3498 N. Three and to staples connected joints also indicated decreasing trend when changing wood from beech to alder and Scotch pine. Results also indicated that increasing number of staple from 2 to 4 in one row joints increased force of the joints. Two prediction equations were derived to predict the shear of one-row multi stapled wood joints. Both equations yielded remarkable results compared to actual laboratory test results.
