Abstract

In this paper, the methods of the safety evaluation for thin-walled shells containing defects based on “Fitness for Service” principle were reviewed. The latest authoritative standards and codes for assessment in both domestic and international fields are introduced. The paper also proposes the existing problems in this field and discusses the main solutions of them. The innovation of the method and technical route mentioned in the resolvent are introduced at the same time. As a result, the trend of safety assessment method for thin-walled shell’s structure containing defects is prospected.
