摘要：木材作为一种弹塑性材料,具有优异的强重比,被广泛应用于木结构建筑。由于其各向异性,木材不同方向的力学性能差异较大,在横纹受压荷载下存在屈服强度低、变形大等受力特征。木材横纹受压破坏现象在工程实际应用中普遍存在且难以避免,若不能及时妥善处理,会严重影响木结构的安全稳定性。由于各地保护政策以及修复技术的限制,对古建筑残损木构件进行增强与加固历来为学者们极力攻克的难题,因此对木材在横纹受压下的性能及加固增强进行研究具有重要意义。文中介绍中国、美国、日本等国家的木材横纹抗压测试标准,并梳理木材横纹受压影响因素的研究现状;概述木材横纹抗压强度的增强方法,尝试提出木材横纹受压及加固增强的发展趋势,以期为今后开展相关研究提供思路。
As an elastoplastic material,wood boasts an excellent strength-to-weight ratio,which renders it a popular choice for wooden structures.However,its anisotropic nature makes the mechanical properties of wood vary significantly in different directions,which endows wood the characteristics such as low yield strength and significant deformation under transverse compression loads.The phenomenon of transverse compression failure of wood is common and unavoidable in engineering applications.If not properly and timely handled,it will seriously affect the safety and stability of wood structures.Due to the limitations of protection policies and restoration technologies in various regions,the reinforcement and strengthening of damaged wooden components in ancient buildings has always been a difficulty that scholars have been striving to overcome.Therefore,the study of the performance and reinforcement of wood under transverse compression is of great significance.This paper introduces the testing standards for transverse wood compression in countries such as China,the United States,and Japan,and summarizes the current research on the influencing factors to wood under transverse compression.With an overview of the methods for reinforcing the transverse compression of wood,the paper attempts to propose the development trend of transverse compression and reinforcement of wood in order to provide ideas for future related research.
