摘要
构造了一种新型的骨状变截面构件。研究表明,采用精心设计的骨状节点,不仅可以解决单层网壳的节点应力集中问题,也将使结构整体性能对缺陷的敏感性,较常规等截面焊接球节点网壳结构大幅降低,同时使施工更为精确和便捷。
Bone- shape beam used in Single Layer Latticed Domes is a new type of variable section beam. Boneshape joint makes the domes more stable and ductile, and less sensitive to the initial imperfections, and avoids stress concentrating on the joint. This type of joints makes construction more convenient, accurate and practical
