摘要

介绍。CLT板的一个显著特征是板(片)在不同层板的交叉排列。由于木材的各向异性,这种设计允许在不同方向的应力作用下具有高强度和刚度,这使得这种材料成为近几十年来最有希望研究的材料之一。本文考察了交叉胶合木板或CLT板的五层板中横向和纵向层的厚度对变形和由此产生的法向和切向应力分布的影响。工作的相关性取决于必须获得计算数据,以分析板的强度特性随纵向和横向层厚度的不同变化而变化,从而选择最有效的板的配置。材料和方法。采用有限元方法,采用SCAD+ PC进行数值计算。同时,三维有限元为平行六面体。设计方案定义为一般型系统,其变形和主要未知量由节点沿X、Y、Z轴的线性位移和围绕这些轴的旋转来表示。作为一种设计结构,我们选择了五层交叉层板,其中外层(1、5)和中央内层(3)为纵向,其余内层(2、4)为横向。简化设计方案为枢支梁。结果。利用SCAD+进行的研究和计算结果制作了显示挠度、法向和切向应力分布与板的横向和纵向层厚度的依赖关系的表格和图表。结论。所获得的数据允许我们评估厚度对五层CLT板的变形能力和应力分布的影响。本研究的意义在于拓展木结构领域的科学技术知识基础。

Влияние толщины поперечных и продольных слоев на деформативность и распределение напряжений в пятислойных плитах древесины перекрестно-клееной
Introduction. A distinctive feature of CLT panels is the cross arrangement of planks (lamellae) in different layers of the board. Due to the anisotropy of wood, this design allows for high strength and stiffness in different directions of stress action, which has made this material one of the most promising to be studied in recent decades. This article examines the influence of the thickness of transverse and longitudinal layers in five-layer slabs of cross-glued timber boards, or CLT panels, on the deformation and distribution of the resulting normal and tangential stresses. The relevance of the work is conditioned by the necessity of obtaining calculated data to analyze changes in the strength characteristics of boards with different variations in the thickness of longitudinal and transverse layers in order to choose the most effective configuration of the board. Materials and methods. The studies were carried out by numerical methods using SCAD+ PC using FEM (Finite element method). At the same time, the three-dimensional finite elements are parallelepipeds. The design scheme is defined as a general-type system, whose deformations and its main unknowns are represented by linear displacements of nodal points along the X, Y, Z axes and rotations around these axes. As a design structure, a five-layer slab with cross-directed layers was chosen in such a way that the outer (1, 5) and central inner (3) layers are longitudinal, and the remaining inner (2, 4) are transverse. The simplified design scheme is a pivotally supported beam. Results. The results of the study and calculations made using SCAD+ were applied to make tables and graphs showing dependence of deflection, distribution of normal and tangential stresses on the thickness of transverse and longitudinal layers of the board. Conclusions. The obtained data allow us to evaluate the influence of thickness on deformability and stress distribution in five-layer CLT panels. The significance of the conducted research is in the expansion of scientific and technical knowledge base in the field of wooden structures.
