- Abstract
The actual use of solid or glued timber elements that are in direct or oblique transverse bending under single or repeated loads is not considered in the current standards. In particular, the formation of folds in the compressed zone of pure bending and obtained a significant margin of safety. Therefore, the concept of "calculated cross-section" is proposed in the article. It describes the distribution of deformations in the height of the cross-section and, also, the layer-by-layer connection between deformations and stresses in a section of bending timber elements by considering the formation of folds in the compressed zone under one-time short-term or repeated loads. Therefore, the method for calculating wooden beams from solid and glued timber using a deformation model was developed. The formation of folds in the compressed zone is predicted by the method of the pure bending zone by analyzing the distribution of stresses on height in the compressed and stretched zones of the calculated cross-section.
