摘要

本文讨论了一种粘结连接模型的制定和分析，其目的是加固或重建软弱的木制构件。采用弹性力学理论的平面应力问题对节点进行建模。假定木材是一种正交各向异性材料。元件的加固是通过附加盖板来实现的，而重建是通过在元件的弱化(恶化)区域引入插入物来进行的。分析了不同板厚和嵌件厚度对粘接件和胶粘剂应力状态的影响。这些分析与轴向载荷单元有关。

Application of adhesive joints in reinforcement and reconstruction of weakened wooden elements loaded axially

The paper concerns the formulation and analysis of an adhesive joint model, aimed at reinforcing or reconstructing weakened wooden elements. The joint is modeled as a plane stress problem of the theory of elasticity. It is assumed that wood is an orthotropic material. The reinforcement of an element is achieved by means of attaching a covering plate, while reconstruction is carried out by introducting an insert into the weakened (deteriorated) zone of an element. The influence of varying thickness of plates and inserts on the stress states in the adherends and adhesive is analyzed. The analyses are related to axially loaded elements.

期刊介绍： Wood. Research papers. Reports. Announcements" ("Drewno") is an international scientific journal that publishes original results of innovatory basic and applied research concerning technological, technical, economic and ecological issues important for the wood science and forest-based industries, including their environment, and interesting to the international recipients. "Drewno" is an Open Access biannual journal. Aims and scope: wood science: anatomy, biology, chemistry, physics wood mechanical and chemical technology, inter alia, sawmilling, composite wood products, wooden construction, furniture making, wood pulp, paper making material engineering, biocomposites, nanocomposites material management environmental protection, safety of the processes, products and working stations biotechnology bioenergy, biofuels forestry: harvesting and wood quality wood-based industries economics The Editorial Board of the journal especially welcomes articles concerning increase in wood resources (wood mobilisation); innovative composites and lignocellulosic materials; new trends in the protection, modification and finishing of wood; biorefining of raw wood material; "green" building; new technologies of wood waste recycling; sustainable development; innovation management; and business networks.
