The bottom node of a cylindrical metal tank consists of bottom shell course, fillet weld and annular plate, and the strength design of the bottom node is of great importance to the whole tank. For the correction of the maximum circumferential stress (primary stress) in tank shell, firstly considered is the combined effect of three circumferential stresses: (1)σa: resulting from M0 for axial shell displacement, (2)σb from M1 and Q1for axial deformation of bottom shell course, and σc from the axial bending stress....

The bottom node of a cylindrical metal tank consists of bottom shell course, fillet weld and annular plate, and the strength design of the bottom node is of great importance to the whole tank. For the correction of the maximum circumferential stress (primary stress) in tank shell, firstly considered is the combined effect of three circumferential stresses: (1)σa: resulting from M0 for axial shell displacement, (2)σb from M1 and Q1for axial deformation of bottom shell course, and σc from the axial bending stress. For the correction of fillet weld,M0 is used as the bending moment in the junction between bottom shell course andfillet weld, which is the critical point for secondary stress correction. For the strength correction for annu-al plate, calculations show that the maximum bending moment exists in the two sides near the central lineof shell plates, and the correction method is the same as for the secondary stress. In addition to the theo-ratical analysis and classification for primary and secondary stresses in bottom node, strength correction is also made for existing tanks and suggestions are given for tank modification.

圆柱形金属油罐下节点包括罐壁底圈板、角焊缝和罐底边缘板,这三部分的强度设计是整个油罐强度设计的关键。对于罐壁最大环向应力(一次应力)校核,首先考虑了三种环向应力的组合值,即液体压力和下节点边缘力系M_0使罐壁产生径向位移引起的环向应力σ_a、第一、二圈罐壁板连接处的边缘力系引起底圈板罐径变化而产生的环向应力σ_b以及轴向弯曲应力在环向引起的波桑应力σ_0。对于角焊缝的强度校核,用M_0作为油罐底圈壁板与下节点角焊缝连接处的弯矩,这是二次应力校核的重点。对于罐底环板的强度校核表明罐壁中心线左、右两侧的弯矩可能为最大,其校核方法与二次应力的校核方法相同。除了对下节点的一次应力和二次应力进行了精确的理论分析和分类外,还对实际运行的大型油罐进行了强度校核,并提出了改进意见。
