摘要: 装配式节点通常采用单根或多根螺栓与构件连接,往往具有一定的半刚性特性。但目前,由于对装配式节点认识不足,在装配式网壳结构分析和设计时,通常假定其节点连接为铰接;然而,通过研究发现实际装配式节点具有较好的半刚性性能;为适应实际工程所研发的新型装配式半刚性节点具有刚度更大、更加高效等优点,可应用于更大跨度的单层网壳结构中。半刚性节点网壳结构具有广阔的应用前景,针对半刚性节点及其网壳性能的研究逐渐成为建筑结构领域的热点研究课题之一。该文综述了国内外半刚性节点及半刚性节点单层网壳结构的现有研究成果以及尚需深入研究的主要问题。文献分析表明,目前针对半刚性节点及半刚性节点网壳结构静力性能的研究已取得一定的成果。然而,关于空间半刚性节点在复杂荷载作用下节点抗弯性能、空间半刚性节点耗能性能、适用于更大跨度的新型空间节点研发、半刚性节点网壳结构动力稳定性等方面有必要进行更多更深入的试验和理论研究,以推动半刚性节点单层网壳结构的实际工程应用。

关键词: 半刚性节点, 抗弯性能, 网壳结构, 静力稳定性, 动力稳定性

Abstract: The assemble joints which are usually connected with members by one or several bolts are named semi-rigid joints. Due to the limit study of assemble joints, they are assumed as pin joints during the analysis and design of structures. However, the study results show that assemble joints are typical semi-rigid joints, and some new assemble joints have the merits of being stiffer and more efficient, which can be used in a larger span single-layer reticulated shell. The reticulated shells with semi-rigid joints have a wide application prospect, and the semi-rigid joint systems and semi-rigidly jointed reticulated shells have become a new research hotspot in the field of engineering structures. A state-of-the-art review of research on the semi-rigid joints and semi-rigidly jointed reticulated shells are thusly present. The research findings are presented and some key issues for further study are suggested. The research on the semi-rigid joints and semi-rigidly jointed reticulated shells has already obtained certain positive results. However, more experimental and theoretical study should be carried out on the joints under complex load combinations, the new joint design for larger span structures, the static and dynamic stability of single-layer reticulated shells with semi-rigid joints. The results should be analyzed and summarized in detail to promote the practical application of single-layer reticulated shells with semi-rigid joints.

Key words: semi-rigid joint, reticulated shell, static stability, failure mechanism, disaster control
