摘要：This study investigates the influence of cross-sectional area and stressed length on the mechanical behavior of wood scrimber, a type of reconstituted engineered wood product increasingly used in construction due to its superior mechanical properties and sustainability. Despite its growing popularity, limited research has been conducted on how the dimensional characteristics of wood scrimber affect its mechanical performance, particularly in terms of size effects. This paper presents experimental results on the compressive and tensile strength of wood scrimber specimens of varying sizes and aspect ratios. The results demonstrate significant differences in the impact of size on tensile strength and compressive strength. Specifically, the study shows that size has a much larger effect on tensile strength than on compressive strength. For tensile strength, the stressed length has a more pronounced impact than the cross-sectional area, with longer specimens exhibiting lower tensile strength. Using the weakest link theory, the study quantifies these size effects, providing a theoretical framework for understanding how the size and geometry of wood scrimber components influence their performance. The findings are crucial for optimizing the use of wood scrimber in structural applications, providing insights into its design and ensuring more reliable and efficient engineering solutions in the construction industry. ?
