Mathematical modeling of stress-strain state of the nodal joint of wooden beams

Abstract

The article presents a study of the joint of wooden beams on a new type of aluminum composite connector. For the numerical experiment, beams with a cross-section of 150x220(h) mm made of solid wood were selected. The beams were connected at the same level in a perpendicular direction to each other. The connecting connectors were made of two types of alloys: 7075 T6 and 6061 T6. The experiment was carried out until the joint was completely destroyed under static load. The elastic operation of the node for different types of connectors under study was maintained until the load of 50 ⋯ 70 kN, after which there was a sharp increase in the deformations of the beams. Conducting a numerical study of the elements of wooden structures made it possible to predict their behavior most accurately in real operating conditions.
