Stages of the stress-strain state of solid and glued wood elements are presented. The concept of the “design cross - section” with a fold in the compressed zone of the element is proposed. © 2024 The Au thors. Published by ELSEVIER B.V.

1. Introduction

Wood is an elastic and plastic anisotropic material of natural origin (Homon et al. (2023), Zakic (1974), Gomon et al. (2019), Da Silva and Kyriakides, S. (2007); Patton-Mallory and Cramer (1987)). Numerous studies by various
