摘　　要：张弦结构应用于现代木结构屋面,不但可以有效增强结构强度、减少木材用量,而且能够丰富结构形态,因此应用非常普遍。作为木屋面结构精细化设计的核心内容之一,张弦节点不仅是张弦结构合理性设计的关键点,而且是结构形态视觉表现的重点部位。本文在初步梳理木屋面张弦结构特点的基础上,分类提取了张弦节点的受力、构造以及表现特征,进而通过案例分析等方法,从技术和形态两方面总结了张弦节点的个性化表现策略。The application of beam string structure in modern timber roof can effectively improve the structural strength, reduce the wood consumption, and enrich the structural forms. So, it’s widely used. As core contents of detailed designs of timber structure roof, the string node is not only the key point of the rational design of the beam string structure, but also the key part of visual performance of structural form. Based on the preliminary analysis of the characteristics of timber string structure roof, this paper classifies and extracts the force, structure and performance characteristics of the string nodes, and then summarizes the strategies on personalized performance strategies of string nodes from the technical and morphological aspects through case analysis and other methods.
