摘要
在分析超大直径焊接空心球受拉节点破坏机理的基础上,提出了一种新的计算大直径球节点承载力的计算准则:即全截面屈服准则,并运用Von—Mises强度理论对模型进行了分析,导出了大直径球节点承载力的新的表达式,公式的计算结果与按冲剪模型理论计算的结果及《JGJ7—91》进行了比较,其一致性较好,弥补了《JGJ7—91》在这方面的不足。
Based on the analysis of collapes mechanism of the super large diameter welded hollow spherical joint, a new hearing capacity fomula of the joint under tension was carried out by using VOA—Mises strength theory and all section yield code. Another fomula of the joint under the punching—shear model was also discussed. At last,the comparision of the two fomulas was discussed.
