空间结构相贯节点设计和加固方法研究

Study on the Design and Reinforced Methods of Tubular Joints

随着施工工艺水平的提高和多维数控切割技术的发展,近年来相贯节点在国内外空间结构领域得到了广泛的应用。在空间结构相贯节点的施工中,由于交汇杆件的数量、角度、尺寸和形状的复杂多样,相贯节点往往成为结构中的薄弱部位。为了保障结构的安全性,相贯节点的设计和加固成为当今研究热点之一。对比分析了国内外相贯节点的设计方法。同时,总结了现有的相贯节点加固方法及其施工方法、特点和研究现状,并进一步提出了相贯节点未来研究课题的看法。

As the construction technology improves and the multidimensional numerical control cutting technology develops,tubular joints have been widely used in space structures at home and abroad recently.In the construction of tubular joints of space structures,due to the complex and diverse number,angle,dimension and shape of the intersectional members,the tubular joints become the weak part in structures.To guarantee the structural safety,the study on the design and reinforced methods of tubular joints has become a key issue recently.The design method of tubular joints at home and abroad is compared and analyzed.Meanwhile,the reinforce method of tubular joints and the corresponding construction methods,characteristics,state-of-the-arts of research are summarized.Furthermore,some view points of further studies on tubular joints are presented.
