Quality of Corner Joints of Beech Chairs under Load

This paper presents quality criteria for corner joints of beech chairs by comparison of break moments during static and dynamic testing of the most frequently used type of construction joints: - round mortise and tenon. Laboratory joint testing using discursive construction methods showed a statistically supported value of the achieved results. The purpose of this paper is to investigate the possibility of shortening the testing procedure of final products and evaluate the quality of final products by segment testing of components in the design phase. The results showed that there is a significant dependence between the Md/Ms coefficient and the number of testing cycles. This opens the possibility of a new, different approach to testing the strength of constructions, using methods for testing assemblies instead of entire final products in accordance with the applicable standard working methods.
