Space truss has developed rapidly in china and designer for its advantage has accepted the sphere soace grid. joints have play very important role in structure. generally, the weided hollow ball joints are adopted. but sometime they can not satisfy the requisition of structure. so a lot of people are busy searching for joints and fouding out all kinds of joints. a new joint - welded hollow truncated joint will be now in this paper
在我國大空間、大跨度的結構越來越多,節點在空間結構中起著重要的作用,焊接空心節點在網架、網殼等空間結構中被大量應用。本文研究的是一種新型的節點? ?焊接空心鼓形節點。 《網架結構設計與施工規程》 jgj7 - 91和《網殼結構技術規程》 jgj61 - 2003隻對空心球節點提出了承載力的計算公式,而沒有引入鼓節點。The conclusion of reappearing analysis is that crane bridge be used as usual because main weld maximum stress of upper cover plate of main beam lower than yield limit though it higher than permissible stress. inner stress of secondary beam was over ultimate strength, and deforming is ultra big. so it was unfit for produce and secondary beam must be changed
再現分析得出的主要結論為:橋架的主樑上蓋板主焊縫的最大應力超過了許用應力,但小於屈服極限,可以繼續投入使用;副梁內部的應力遠遠超過了強度極限,變形特別嚴重,不能滿足生產要求,因此更換新的副梁;端梁內部的應力超過了屈服極限,小於強度極限,在應力較大的位置焊接補強板;投入使用后,要對整個橋架進行定期檢查。
