壳体表面的初始压力通常是在各种平板的轧制或焊接过程中产生的。提出与现行规范相关的基本设计规则非常重要。本文重点介绍壳体制作过程中由平板边缘的持续焊接造成的纵向缺陷。将14个试验试件分成2组,分别称之为SCC和DCC,并施加均匀静水压力。随着厚度由1t,2t增大到3t(t为薄壳厚度),试件出现1条或2条直线缺陷。该文得到的研究结果与国际上的规范及关于初始和整体屈曲及破坏的理论基本吻合。
The initial pressure on the shell surface is usually generated during the rolling or welding of various plates. It is important to come up with basic design rules that are relevant to the current norms. This article focuses on the longitudinal defects caused by the continuous welding of the edge of the plate during the production of the shell. The 14 test specimens were divided into two groups, referred to as SCC and DCC, respectively, and applied with uniform hydrostatic pressure. With the thickness from 1t, 2t increased to 3t (t is the shell thickness), the specimen appeared one or two straight line defects. The research results obtained in this paper are basically consistent with the international norms and the theories about initial and global buckling and destruction.
