Analysis on Ultimate Load-Bearing Capacity of K-type Ring-Stiffened Drum-Type Steel Tubular Joint
【摘要】 根据圆钢管相贯节点的特性,提出了鼓型钢管节点构造形式,利用ANSYS非线性有限元分析方法,分别计算了在主支管相交区设置了不同方式、不同数量、不同厚度和大小加强环的鼓型钢管节点的极限承载力和刚度,并与非加强K型钢管相贯节点的极限承载力比较.结果表明,鼓型钢管节点可以提高钢管节点的极限承载力和刚度.
【Abstract】 A new structure named drum-type steel tubular joint is invented on the basis of its characteristics.The ultimate load-bearing capacity and rigidity of ringstiffened drum-type steel tubular joint are calculated in different ways,inclading different numbers,thicknesses and sizes of ring-stiffener parameters using the ANSYS non-linear finite element analysis.They are compared with those of unstiffened K-type tubular joint.Results from this study show that the ringstiffened drum-type steel tubular joint can improve the ultimate load-bearing capacity and rigidity of the tubular joint.
【Key words】 drum-type steel tubular joint; ring-stiffener; ultimate load-bearing capacity; ANSYS;
