Abstract :In this study, the effect of diagonal static loads on wooden joints in the production of solid wooden chairs was examined. According to the principle of equal moment distribution, the optimum chair frame and minimum required cross-section components were determined by considering the stresses on joints. Therefore, the location of the bottom frame component was optimized on the most critical sitting position of the chair. According to the diagonal load applied, the performance of the joint construction was determined by testing on the position. In the preparation of samples for testing, first class beech and scotch pine were selected, while polyvinyl acetate insert ignore into journalissuearticles values(PVA); adhesive was preferred for assembly. At the end of the experiments, it was observed that the most critical parts of the joints in terms of the stability of chair were the mortise and tenon joint, and adhesive bonding of the mortise and tenon joint. In order to determine the optimum chair frame and minimum required cross-section of the joint, the relationship between points 2 and 5 with the test load on component 1 was determined as follows. N = F x cos a T = F x sin a M2 = T x L x k M5 = M2 x k2
