ジャーナル フリーLarge aboveground oil storage tanks are unanchored and rest freely on flexible foundation. The shell-to-annular joint of unanchored oil storage tanks will uplift due to strong seismic excitation, and a large plastic strain occurs in this joint. This paper presents the elastic-plastic, large deformation behavior of the uplifted shell-to-annular joint using axisymmetric finite element analysis. In the analysis, the uplift behavior is assumed to be axisymmetric. The constitutive equation is based on the J2 flow theory with the kinematic hardening rule. The updated Lagrangian approach is used for the formulation of large deformation. The strength of the shell-to-annular joint in a large tank with capacity 90, 000m3 is reported. While deformation, stress and strain of the joint at uplift are described, it verifies also about mesh division, relation between equivalent stress and equivalent plastic strain, and partial penetration welding.抄録全体を表示PDF形式でダウンロード (1907K) -

ジャーナル フリーIn this study, the residual stress analysis in repair welds of dissimilar pipe joint using temper bead technique was performed by means of Iterative Substructure Method (ISM) for fast computation of thermal elastic-plastic finite-element analysis. The mock-up test was also performed to measure the residual stress in repair welds of dissimilar pipe joint using temper bead technique. The analytical result was compared with the experimental result to confirm the accuracy of the developed residual stress analysis. As the result, residual stress distributions in repair welds were in good agreement between analytical and experimental results. Finally, the distribution characteristics of residual stress in repair welds of dissimilar pipe joint were discussed further based on the analytical results. Thus it was concluded that the developed residual stress analysis has the potential to become useful for accurate prediction and evaluation of residual stress distribution in repair welds.抄録全体を表示PDF形式でダウンロード (1388K)
