现代木结构研究进展

木结构在我国具有悠久历史，是我国传统建筑文化的主要传承形式。现代木结构作为装配式建筑形式之一，在发达国家已有百余年历史，主要形成了以轻型木结构、胶合木结构和木混合结构为代表的结构形式，而近年来现代木结构在我国科研与应用领域也得到广泛关注。对我国现代木结构研究开展了系统的回顾与总结，主要从五个方面系统梳理了我国现代木结构的研究进展，即材料性能及加工、构件性能及创新、连接性能与进展、体系研究与开发、防火研究及需求。通过对我国现代木结构材料、构件、连接及体系等研究工作的全面梳理，分析了我国现代木结构的研究现状、存在的问题与发展趋势，指出原材料可持续利用、产品质量认证体系建设、关键技术创新与研究、设计理论与规范体系完善等研究趋势，可为今后的研究工作提供参考，同时也将有助于推动相关工程应用的开展。

Research progress on modern timber structures

Timber structure has a long history and is the main form of inheritance of the traditional architectural culture in China. As a kind of prefabricated structures, modern timber structures have been developed for more than one hundred years. The typical structural systems include light-frame timber structures, glued laminated timber structures and hybrid timber structures. In recent years, mordern timber structures have attracted increasingly more attention in the research community and in the engineering applications in China. This paper presents acomprehensive review of the main research advances of modern timber structures in China. It systematically summarizes the latest research progress on the modern timber structures in China in the following five aspects: material properties and procession, behavior and innovation of structural members, joints,investigation and development of structural systems, fire resistance and research needs. Through the comprehensive review on the research of materials, structural members, joints and structural systems, it presents an in-depth analysis on the research status, the existing problems and the development trend of modern timber structures in China.Finally, the paper put forward the further research needs which include the sustainable use of the materials, quality certification systems of products, innovation and research of the key technology and perfecting of the design theories and specifications. This work can provide a reference for future research, and also promote the development of relative engineering applications.
