摘要
相贯节点体系具有外观简洁、传力明确、施工方便、构造简单、节省建筑材料和易于维护保养等诸多优点,被广泛应用于空间结构当中。本文简要介绍了相贯节点的破坏模式、破坏原因和主要影响因素,总结了国内外相贯节点的静力承载性能、刚度性能、疲劳性能和动力性能,分析了相贯节点高温承载性能研究现状。本文内容能为相贯节点的设计和未来发展方向提供参考依据。
Tubular joints are widely used in space structures due to their advantages such as aesthetic appearance,clear loading path,easy construction,simple configuration,material saving and easy maintenance.This paper introduced the failure modes of tubular joints,the reasons of joint failure and the major parameters.The static bearing capacity,stiffness,fatigue behaviour and hysteretic behavior were summarized.Meanwhile,the state of the art of researches on the mechanical behaviour of tubular joints at elevated temperature was analyzed.This paper could serve for the design method and further study of tubular joints.
