Abstract :In this study, the strength properties of glued-dowel joined sofa frames constructed of solid wood and wood based composite materials were investigated. Furthermore, the place of the stretcher was optimized in the side frame of the sofa. Scotch pine insert ignore into journalissuearticles values( Pinus Sylvestrıs Lipsky ); and Turkish beech insert ignore into journalissuearticles values( Fagus Orientalis Lipsky ); were used as solid wood materials. Oriented strandboard insert ignore into journalissuearticles values(OSB);, okoume insert ignore into journalissuearticles values( Aucoumea klaineana pierre ); plywood insert ignore into journalissuearticles values(PLY); and medium density fiberboard insert ignore into journalissuearticles values(MDF); were used as wood composites. Specimens were tested under static load according to the principles of TS 9215 by applying both seat and backrest loads which the sofa can be imposed upon in service. The finite element method was utilized for analyzing the sofa frames. As a result, it has been observed that the three dimensional structural analysis by means of the finite element method gives reasonable estimates of the overall strength performances of the sofa frames. Furthermore; it was concluded that the wood composite materials could be used instead of solid wood materials in the production of the frame construction furniture, especially in the upholstered seating furniture frames.
