【摘要】：为研究初始几何缺陷对加肋凸型锥-环-柱结合壳连接分段极限承载能力的影响,参考现行规范对初始几何缺陷的要求,设计了初始几何缺陷的不同组合作为计算方案。建立了含不同初始几何缺陷形态的锥-环-柱结合壳连接分段模型,采用弧长法,分析连接分段的极限承载能力及破坏形式,并探讨了几何修正系数Cg的计算方法。结果表明:不同形态的初始几何缺陷对连接分段极限承载能力的影响有所区别;含加肋凸型锥-环-柱结合壳连接分段的极限承载能力几何修正系数可参考本文结论。
[Abstract]:In order to study the effect of initial geometric defects on the ultimate load-bearing capacity of stiffened convex cone-toroidal combined shell connections, different combinations of initial geometric defects are designed as calculation schemes according to the requirements of current codes for initial geometric defects. A segmental model of cone-ring-column combined shell connection with different initial geometric defects is established. The ultimate bearing capacity and failure form of the connection segment are analyzed by arc length method, and the calculation method of geometric correction coefficient Cg is discussed. The results show that the effect of initial geometric defects of different shapes on the ultimate load-bearing capacity of joints is different, and the geometric correction coefficient of ultimate load-bearing capacity of cone-circular cylindrical and shell connections with stiffened convex type can be referred to the conclusion of this paper.
