Aug 01, 2017 · Both the experimental and numerical results indicated that the peak stress occurs at the shell-to-bottom fillet weld, the major hazard in oil tanks, where a rupture may ultimately occur. The stresses on the shell-to-bottom fillet weld are relatively complex, and the stress distribution there is influenced by the annular bottom plate and concrete ringwall.Cited by: 5Publish Year: 2017Author: Lei Shi, Lei Shi, Jian Shuai, Xiaolin Wang, Kui Xusp.info Welded Steel Pipe - Steel TankOct 07, 2010 · Photographs used in this volume are courtesy of Victaulic, National Welding Corp. and STI/SPFA (Steel Tank Institute/Steel Plate Fabricators Association).
