摘　　要：木结构具有绿色环保、低碳节能等优势,其发展与应用有助于推动我国“双碳”目标的实现。作为木结构形式之一,木互承结构是由相互支承的木构件通过循环互承围合形成的空间格构体系,在古代桥梁建造上多有应用。近年来,木互承结构在空间结构领域的研究及应用逐渐增多。笔者梳理了木互承结构在形态学和力学性能等方面的国内外研究进展,讨论其发展现状与亟须解决的关键性技术问题。形态学研究表明,木互承结构找形理论众多,可根据图论、力平衡状态、迭代算法和空间解析几何法分为4类,但仍需进一步设计出简便易操作的通用型软件。木互承结构的力学性能研究目前主要集中于节点性能和整体受力性能方面,但在高性能节点和结构稳定性方面仍需进一步探索和研究。对木互承结构的工程应用进行了梳理和总结,可为其未来的研究与应用提供参考。相信伴随着木材科学与现代木结构技术的发展,构件规则、节点统一、造型丰富的木互承结构将越来越广泛应用于木结构工程建设项目中。Timber structure has the advantages of environmental-friendly, low-carbon emission, and energy-saving. The popularization of timber structures helps to promote the realization of the goals of carbon peaking and carbon neutrality. The timber reciprocal structure is a spatial lattice system formed by the cyclic enclosure of reciprocally supported timber elements, which has many applications in ancient bridge constructions. Recently, the research and application of timber reciprocal structures have increased with the development of timber spatial structures. Although the timber reciprocal structure has developed rapidly in the developed countries, the development of timber reciprocal structure is still in developing in China. Based on the investigation of scientific research of timber reciprocal structures in both developed and developing countries, the research progress of morphological and mechanical performance of timber reciprocal structures was reviewed. Besides, the development status and the key design technologies were discussed. The morphological research showed that the form-finding methods of timber reciprocal structures were complete and numerous. According to the graph theory, force balance, iterative algorithm and analytic geometry methods, the form-finding methods were divided into four categories, while the optimization process was complicated. To realize the rapid formation of structural configuration in engineering applications, more feasible form-finding theories and more easy-to-operate interactive tools are necessary to be developed. The research on the mechanical performance of timber reciprocal structures mainly focuses on the connections and overall stress. Existing research on the mechanical behavior of timber reciprocal structures is not systematic enough. Except for the research on enhancing joint performance and structural stability, the research on structural capacity and stability needs to be strengthened. Moreover, some key design technologies such as the wind resistance, seismic perfo
