摘要
中国木结构古建筑具有独特的营造方式和结构体系,蕴藏着数量众多且类型丰富的连接界面,这些界面的摩擦对古建筑节点、结构的抗震性能起到至关重要的作用。基于现有摩擦学理论,阐述木材连接界面的摩擦机理,探究连接界面摩擦对木结构古建筑各单元层抗震的作用机制。通过分析木结构的营造特点,梳理木材连接界面摩擦及其对木结构古建筑抗震作用的研究现状,指出木材摩擦性能是评估木结构古建筑稳定性与抗震性能的关键指标,为木结构古建筑的进一步研究和保护提供参考。
The timber structures in ancient Chinese buildings exhibit unique construction techniques and structural systems,with numerous and diverse connection interfaces.The friction at these interfaces plays a critical role in the seismic performance of both the joints and the overall structure.Drawing on established tribological theories,this paper delves into the friction mechanisms at timber connection interfaces and examines how they affect the seismic resistance of various structural units.By reviewing the construction characteristics of timber structures and current research on timber interface friction,this study highlights that the frictional properties of wood are key to evaluating the stability and seismic performance of these ancient structures.The findings provide valuable insights for future research and preservation of ancient timber buildings.
